Organization [Abstract]
Organization	1. Organization SAI.TECH Global Corporation, formerly known as TradeUP Global Corporation (the “Company” or “SAI.TECH”), was incorporated in the Cayman Islands on February 2, 2021. The Company, through its subsidiaries, is primarily engaged in sales of crypto assets mining machines to end customers, specialized hosting service to crypto asset mining customers, digital mining and mining pool service and other service globally. a. Reverse recapitalization On April 29, 2022, the Company consummated the previously announced business combination (the “Business Combination”) with SAITECH Limited, a Singapore based digital mining operator. Following the closing of the Business Combination, SAITECH Limited became a wholly owned subsidiary of TradeUP Global Corporation (“TradeUP”), which subsequently renamed to “SAI.TECH Global Corporation”. The transaction is accounted for as a recapitalization, SAITECH Limited is determined as the predecessor and the historical financial statements of SAITECH Limited became the Company’s historical financial statements, with retrospective adjustments to give effect of the recapitalization. The equity is restated using the exchange ratio of 0.13376 established in the recapitalization transaction, which is $188 million and $10.00 per share (the “exchange ratio”) divided by 140,551,496 (total ordinary shares outstanding of SAITECH Limited), and together with holders of 3,492,031 TradeUP Class A Ordinary Shares, remaining after the redemption of 2,071,735 shares, received 3,492,031 Class A Ordinary Shares, holders of 272,247 TradeUP Class B Ordinary Shares received 272,247 Class A Ordinary Shares, and holders of 2,244,493 TradeUP Warrants received Warrants to purchase 2,244,493 Class A Ordinary Shares, to reflect the equity structure of the Company. Following completion of the Business Combination, holders of 28,000,000 SAITECH Limited Class A Ordinary Shares, remaining after the redemption of 24,254,751 shares, received 3,745,249 Class A Ordinary Shares, holders of 2,040,816 SAITECH Limited Series Seed Preferred Shares, remaining after the redemption of 1,767,838 shares, received 272,978 Class A Ordinary Shares, holders of 7,288,630 SAITECH Limited Series Angel Preferred Shares, remaining after the redemption of 6,313,711 shares, received 974,919 Class A Ordinary Shares, holders of 14,599,115 SAITECH Limited Series Pre-A Preferred Shares, remaining after the redemption of 12,646,352 shares, received 1,952,763 Class A Ordinary Shares, and holders of 16,622,935 SAITECH Limited Series A Preferred Shares, remaining after the redemption of 14,399,469 shares, received 2,223,466 Class A Ordinary Shares. There is an aggregate of 12,933,653 Class A Ordinary Shares issued and outstanding, and 2,244,493 Class A Ordinary Shares issuable upon the exercise of the warrants to purchase Class A Ordinary Shares outstanding, with an exercise price of $11.50 per share. Loss/(income) per share is retrospectively restated using the historical weighted-average number of ordinary shares outstanding multiplied by the exchange ratio. The par value of ordinary shares remained $0.0001, the subscription receivable was adjusted retrospectively from negative $9 to $ nil The consolidated statements of changes in equity for the years ended December 31, 2021 and 2020 were also adjusted retrospectively to reflect these changes. The weighted average number of ordinary shares outstanding used in computing net loss per ordinary share — basic and diluted was adjusted retrospectively from 93,061,216 to 18,800,009 for the years ended December 31, 2021 and 2020. The loss per share before and after the retrospective adjustments are as follows. Year Ended December 31, 2020 2021 Before After Before After Net loss per share attributable to ordinary shareholders of SAI.TECH Global Corporation. – Basic and diluted — — (0.0019 ) (1.4274 ) Weighted average shares used in calculating net loss per share – Basic and diluted 93,061,216 12,447,760 93,061,216 12,447,760 b. Reorganization Prior to the Business Combination, SAITECH undertook a series of steps as follows to restructure its business (the “Reorganization”): The Company incorporated Superlative Accelerating Infinite Limited (“Superlative Accelerating”) under the laws of the British Virgin Islands and Superlative Accelerating incorporated Silicon Asset Investment Limited (“Silicon Asset”) under the laws of Hong Kong, as its wholly owned subsidiary, in April 2021. In April 2021, Silicon Asset incorporated a wholly owned subsidiary, Hangzhou Dareruohan Technology Co., Ltd. (“SAI WOFE”) in Hangzhou, the PRC. Effective on April 22, 2021, the Company acquired control over Beijing SAI and its subsidiary, Xinjiang Silicon Substrate Heating Power Co., Ltd. (“Xinjiang Silicon”) by entering into a series of contractual agreements (the “VIE Agreements”). The VIE Agreements enable SAI WOFE to (i) have power to direct the activities that most significantly affect the performance of Beijing SAI, and (ii) receive the benefits of Beijing SAI that could be significant to Beijing SAI. SAI WOFE is fully and exclusively responsible for the management of Beijing SAI, absorbs all risk of losses of Beijing SAI and has the exclusive right to exercise all voting rights of Beijing SAI’s shareholders. Therefore, in accordance with ASC 810 “Consolidation”, SAI WOFE is considered as the primary beneficiary of Beijing SAI and its subsidiary and has consolidated Beijing SAI’s assets, liabilities, results of operations, and cash flows in the accompanying consolidated financial statements. Beijing SAI is controlled by the same shareholder since incorporation and after the reorganization. Accordingly, Beijing SAI became the VIE of the Company and the Company, through its wholly owned subsidiaries, Superlative Accelerating, Silicon Asset and SAI WOFE, become the primary beneficiary of Beijing SAI and its subsidiary (the “Reorganization”). Since the Company, its wholly owned subsidiaries and the VIE were effectively controlled by the same shareholders immediately before and after the Reorganization completed on April 22, 2021, as described above, the Reorganization was accounted for as a recapitalization. As a result, the consolidation of the Company, its subsidiaries and the VIE has been accounted for at historical cost, as a transaction between entities under common control in a manner similar to polling of interest for the year ended December 31, 2020. On August 31, 2021, the Company terminated the VIE Agreements. As a result, the corporate structure of the Company no longer contains a VIE structure starting from August 31, 2021. c.

Summary of Significant Accounting Policies	12 Months Ended

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies a) Basis of presentation The Company’s consolidated financial statements are prepared and presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). b) Principles of consolidation The accompanying consolidated financial statements include the accounts of us and our subsidiaries, of which we are the primary beneficiary, from the dates they were acquired or incorporated. All inter-company transactions and balances have been eliminated upon consolidation. c) Liquidity For the year ended December 31, 2023, the Company had a net loss of $6,120 and net cash outflow in operating activities of $3,125. As of December 31, 2023, our consolidated current assets exceeded our consolidated current liabilities by $11,565, we had cash and cash equivalents of $3,176, crypto assets and stablecoins assets of $6,790 , and accumulated deficit of $31,345. The Company believes its current cash and crypto assets on hand is sufficient to meet its operating and capital requirement for at least the next twelve months from the date these financial statements are issued. d) Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of these consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. The Company continually evaluates these estimates and assumptions based on the most recently available information, historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Significant accounting estimates reflected in the Company’s consolidated financial statements include but are not limited to estimates and judgments applied in determination of allowance for doubtful receivables, impairment losses for long-lived assets including intangible assets, impairment loss for cryptocurrencies, valuation allowance for deferred tax assets, provision for inventory, estimated forfeiture rate in calculation of share-based payment, estimated interest rate on calculation of operating lease. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from those estimates. e) Foreign currency translation and transactions Historically the Company’s principal country of operations is the PRC. The financial position and results of its operations are determined using RMB, the local currency, as the functional currency. The Company’s financial statements are reported using U.S. Dollars (“US$”, or “$”). The functional currency for the Company in Cayman Island is US$. Assets and liabilities are translated using the exchange rate at each balance sheet date. The consolidated statements of operations and comprehensive (loss)/income and cash flows denominated in foreign currency are translated at the average rate of exchange during the reporting period, and shareholders’ equity/(deficit) is translated at historical exchange rates. Adjustments resulting from the translation are recorded as a separate component of accumulated other comprehensive (loss)/income in shareholders’ equity. The value of RMB against US$ and other currencies may fluctuate and is affected by, among other things, changes in the PRC’s political and economic conditions. Any significant revaluation of RMB may materially affect the Company’s financial condition in terms of US$ reporting. The following table outlines the currency exchange rates that were used in creating the consolidated financial statements in this report: As of As of Balance sheet items, except for equity accounts 6.9646 7.0827 For the Year Ended December 31, 2021 2022 2023 Items in the consolidated statements of operations and comprehensive (loss)/income, and cash flows 6.4000 6.7190 7.0422 No representation is intended to imply that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate stated above, or at any other rate. f) Cash and cash equivalents Cash and cash equivalents consist of bank deposits, which are unrestricted as to withdrawal and use. The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. g) Accounts receivable The Company records accounts receivable at net realizable value consisting of the carrying amount less an allowance for uncollectible accounts as needed. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on aging data, historical collection experience, customer specific facts and economic conditions. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of December 31, 2023 and 2022, the Company did not record any allowances for doubtful accounts against its accounts receivable. h) Inventories Inventories, consisting of digital mining cabinets and related accessories for the production purpose, are stated at the lower of cost or net realizable value. The cost of inventory is determined using the identified cost of the specific item. Inventory is written down for damaged and slow-moving crypto asset mining machines, which is dependent upon factors such as historical and forecasted consumer demand and expected selling price. Write downs are recorded in cost of revenues in the consolidated statements of operations and comprehensive (loss)/income. For the year ended December 31, 2023 and 2022, the Company did not recognize any write down on inventories. i) Crypto assets Crypto assets purchased are recorded at cost and Crypto assets (mainly bitcoin) awarded to the company though its mining activities are accounted for in connection with the Company’s revenue recognition policy. Crypto assets (bitcoin) are included in current and other assets in the accompanying Consolidated Balance Sheets due to the Company’s ability to sell bitcoin in a highly liquid marketplace and the selling of bitcoin to fund operating expenses to support operations. Crypto assets held are accounted for as intangible assets with indefinite useful lives. Crypto assets are measured on a first-in-first-out (“FIFO”) in order to more accurately reflect the disposition of company’s crypto assets. ASC 350-60 provides guidance on classifying proceeds from bitcoin and concludes that bitcoin converted nearly immediately into cash would qualify as cash flows from operating activities. All other sales would qualify as investing activities. The Company evaluates its sales of bitcoin and will record crypto assets sold nearly immediately as operating cash flows and the remainder will be recorded as investing activities. During year ended December 31, 2023, all proceeds from bitcoin sales were classified as investing activities. As a result of adopting ASC 350-60 on October 1, 2023, crypto assets are measured at fair value as of each reporting period. The fair value is measured using the period-end closing crypto assets price from its principal market in accordance with ASC 820, Fair Value Measurement. Effective January 1, 2023, the Company early adopted ASU 2023-08, which requires entities to measure crypto assets at fair value with changes recognized in the Consolidated Statement of Operations and Comprehensive Income (Loss) each reporting period. The Company’s crypto assets are within the scope of ASU 2023-08 and the transition guidance requires a cumulative-effect adjustment as of the beginning of the current fiscal year for any difference between the carrying amount of the Company’s crypto assets and fair value. As a result of the Company’s early adoption of ASU 2023-08, the Company recorded a $79 increase to crypto assets and a $79 increase to accumulated deficit on the Consolidated Balance Sheets as of the beginning of the fiscal year ended December 31, 2023. Prior to the adoption of ASU 2023-08, crypto assets were accounted for as intangible assets with indefinite useful lives and are recorded at cost less impairment in accordance with ASC 350 – Intangibles-Goodwill and Other Fair Value Measurement Crypto assets generated from the crypto assets mining business and the mining pool business as well as the crypto assets distributed to mining pool participants are included within operating activities in the accompanying consolidated statements of cash flows. The sales of crypto assets are included within investing activities in the accompanying consolidated statements of cash flows and any realized gains or losses from such sales are included in gain or loss of disposal of crypto assets in the consolidated statements of operations and comprehensive (loss)/income. j) Stablecoin assets Stablecoin is included in current assets in the accompanying consolidated balance sheets. The Company holds positions in the stablecoins USD Coin (USDC), which are crypto assets, but are considered a financial instrument in accordance with ASC Topic 825. These stablecoins are recognized in the consolidated balance sheets as investment recognized at fair value. k) Property and equipment, net The Company records plant not yet placed into service as construction in progress. Once the plant is completed and operational, the construction in progress is reclassified to “Plant” and depreciated over the estimated useful life. The Company’s property and equipment are recorded at cost less accumulated depreciation and impairment loss, if any. Depreciation is calculated on the straight-line method after taking into account their respective estimated residual values over the following estimated useful lives: Item Useful lives Radio of Furniture, fixture and other equipment 3 years 5 % Electronic equipment 3 – 5 years 5 % Plant Shorter of useful life or lease term 0 % When property and equipment are retired or otherwise disposed of, resulting gain or loss is included in net income in the period of disposition. For the year ended December 31, 2023, 2022 and 2021, the Company recognized $402, $718 and$317 on loss from disposal of property and equipment, net. l) Intangible assets, net The Company’s intangible assets primarily consisted of purchased software used for specific crypto asset mining machines to increase the computing power or reduce power consumption. The software is initially recorded at purchased cost and amortized on a straight-line basis over the estimated useful lives of 3 years. , the intangible asset has been amortized to 0. m) Construction in process Direct costs that are related to the construction of equipment and incurred in connection with bringing the assets to their intended use are capitalized as construction in process. Construction in process is transferred to specific plants and equipment items and the depreciation of these assets commences when the assets are ready for their intended use. n) Impairment of long-lived assets All long-lived assets, which include tangible long-lived assets and intangible long-lived assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of the asset to the estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recognized for the difference between the carrying amount of the asset and its fair value. For the year ended December 31, 2023, 2022 and 2021, the Company recognized $138, $912 and nil o) Fair value of financial instruments The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable and stablecoin. The carrying values of these financial instruments’ approximate fair values due to their short term in nature. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This topic also establishes a fair value hierarchy which requires classification based on observable and unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter. p) Revenue recognition In accordance with ASC Topic 606, revenues are recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. In determining when and how much revenue is recognized from contracts with customers, the Company performs the following five-step analysis: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; (5) recognize revenue when (or as) the entity satisfies a performance obligation. The Company assesses its revenue arrangements against specific criteria in order to determine if it is acting as principal or agent. Sales of products Revenue generated from sales of products occurs for the sales of crypto asset mining machines to end customers. The Company presents the revenue generated from its product sales on a gross basis as the Company acts as the principal and has control of the goods and has the ability to direct the use of goods to obtain substantially all the benefits. In making this determination, the Company also assesses whether it is primarily obligated in these transactions, is subject to inventory risk, has latitude in establishing prices, or has met several but not all of these indicators. Revenues are measured as the amount of consideration the Company expects to receive in exchange for transferring control of products to customers. Consideration from product sales is recorded net of value-added tax, and there is generally no other performance obligation other than the delivery of products. Proceeds from product sales are recognized as revenue at the point in time when the receipt of product is confirmed by the customer. Hosting service Revenues generated from hosting service is earned by the Company to perform hosting service and daily maintenance of servers for customers throughout the contractual period. The single performance obligation is to provide an environment for the servers to operate continuously which is satisfied over time. Such hosting service revenue is recognized over time as the performance obligation is satisfied over the term of the contracts with customers. Mining pool services The Company operates its mining pool, Sai.plus, to enable providers of computing power (“pool participants”) to participate in crypto-mining activities in an efficient manner in the blockchain network, in exchange for a fee (“pool operator fee”) for its coordination efforts as the pool operator. The Company receives all the mining rewards in its own name, and then allocates mining rewards to each pool participant net of the pool operator fees based on the sharing mechanism predetermined. The mining rewards include the block rewards and the transaction verification fees related to the transactions included in the block. The Company considers itself the principal in transactions with the blockchain networks and recognizes the mining pool revenue on a gross basis. The performance obligation is to create or validate each block. Revenue is recognized at the point when the block creation or validation is complete, and the Company has received the rewards. Revenue is measured at the fair value of rewards upon receipt, which is not materially different than the fair value at contract inception. The Company considers itself the principal in transactions with the blockchain networks as it coordinates all the computing power within the mining pool, delivers such aggregated computing power to the blockchain network, collects centrally all mining rewards and distributes them in accordance with the predetermined sharing mechanisms. The Company has control over the pool participants’ computing power. Although the pool participants can enter and exit the pool at will and deploy the qualifying types of mining machines at the choices of the pool participants, during the mining process, the Company dictates the tasks and the participants’ mining machines merely follow the allocation prescribed by the Company. As a result, the Company is primarily responsible for fulfilling the promise to provide the specified service. Further, under existing sharing mechanisms, the Company is exposed to the risk that actual block rewards may differ from expected rewards, therefore, bears the inventory risk before the specified service has been transferred to a customer. The Company provides mining pool services under Sai.plus. Mining Revenue. The Company have q) Income taxes The Company follows the guidance of ASC Topic 740 “Income taxes” and uses liability method to account for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Company records a valuation allowance to offset deferred tax assets, if based on the weight of available evidence, it is more-likely-than-not that the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in statement of operations and comprehensive (loss)/income in the period that includes the enactment date. r) Uncertain tax positions The Company uses a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As a result, the impact of an uncertain income tax position is recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest on non-payment of income taxes under requirement by tax law and penalties associated with tax positions when a tax position does not meet the minimum statutory threshold to avoid payment of penalties recognized, if any, will be classified as a component of the provisions for income taxes. The tax returns of the Company’s Hong Kong and PRC subsidiaries and VIE are subject to examination by the relevant local tax authorities. According to the Departmental Interpretation and Practice Notes No.11 (Revised) (“DIPN11”) of the Hong Kong Inland Revenue Ordinance (the “HK tax laws”), an investigation normally covers the six years of the assessment prior to the year of the assessment in which the investigation commences. In the case of fraud and willful evasion, the investigation is extended to cover ten years of assessment. According to the PRC Tax Administration and Collection Law, the statute of limitations is three years if the underpayment of taxes is due to computational errors made by the taxpayer or the withholding agent. The statute of limitations is extended to five years under special circumstances, where the underpayment of taxes is more than RMB100,000. In the case of transfer pricing issues, the statute of limitation is ten years. There is no statute of limitation in the case of tax evasion. For the year ended December 31 2023, 2022 and 2021, the Company did not have any material interest or penalties associated with tax positions. The Company did not have any significant unrecognized uncertain tax positions as of December 31, 2023 and 2022. The Company does not expect that its assessment regarding unrecognized tax positions will materially change over the next 12 months. s) Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker (the “CODM”), which is comprised of certain members of the Company’s management team. Consequently, the Company has determined that it has two reportable operating segments. In addition, the Company’s chief operating decision maker makes resource allocation decisions and assesses performance based on the different business operating results instead of the geographic location operating results. Therefore, no geographical segments are presented. t) Earnings per share Earnings (loss) per share is computed in accordance with ASC 260. The two-class method is used for computing earnings per share in the event the Company has net income available for distribution. Under the two-class method, net income is allocated between ordinary shares and participating securities based on dividends declared and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. Series Angel and Series Pre-A Preferred Shares issued by the Company qualified as participating securities because they have the same participating rights on the earnings of the Company as ordinary shares on an as-converted basis after the preferred shareholders receive non-cumulative annual dividends up to 100% of the original issue price for each of the preferred shares. Basic earnings (loss) per ordinary share is computed by dividing net income/(loss) attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the period. Diluted earnings/(loss) per share is calculated by dividing net income/(loss) attributable to ordinary shareholders by the weighted average number of ordinary and potential ordinary shares outstanding during the period. Potential ordinary shares include ordinary shares issuable upon the conversion of the preferred shares using the if-converted method. Potential ordinary shares are not included in the denominator of the diluted earnings per share calculation when inclusion of such shares would be anti-dilutive or in the case of contingently issuable shares that all necessary conditions for issuance have not been satisfied. For the year ended December 31 2023, 2022 and 2021, there were no dilutive shares. u) Share based compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the cost over the period the employee is required to provide service in exchange for the award, which generally is the vesting period. The Company recognizes compensation cost for an award with only service conditions that has a graded vesting schedule on a straight-line basis over the requisite service period for the entire award, net of estimated forfeitures, provided that the cumulative amount of compensation cost recognized at any date at least equals the portion of the grant-date value of such award that is vested at that date. Forfeiture rates are estimated based on historical and future expectations of employee turnover rates. v) Commitments and contingencies The Company accrues estimated losses from loss contingencies by a charge to income when information available before financial statements are issued or are available to be issued indicates that it is probable that an asset had been impaired, or a liability had been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred. As of December 31, 2023 and 2022, there were no contingent liabilities relating to litigations against the Company. w) Leases In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. The amendments in this ASU requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. x) Reclassification of assets and stablecoins As Tether reserves the right under its user agreement to redeem USDT by in-kind redemptions of other assets it holds in its reserves and as Tether has held precious metals and other non-financial assets in its reserves, it does not appear that USDT meets the definition of a financial instrument under ASC 825-10-20. The Company reclassified USDT, amounting $ as of December 31, 2022, from stable coins to assets. The reclassification had no impact on net assets as of December 31, 2022, and revenues and net loss for the year ended December 31, 2022.

Redeemable Preferred Shares [Abstract]
Redeemable Preferred Shares	10. Redeemable Preferred Shares Series A Preferred Shares Issuance On April 22, 2021, the Company entered into an investment agreement with certain investors, to issue 16,466,767 series A preferred shares (“Series A Preferred Shares”), with par value of US$0.0001 each, for an aggregated consideration of US$8,156. The issuance price of the Series A Preferred Shares is US$0.4953. In addition, the Company was committed to issue 9,864,312 Series Pre-A Preferred Shares to three shareholders holding a total 7.99% equity interest of Beijing SAI, who are currently in the progress of changing from a shareholder of Beijing SAI to a direct investor of the Company (Note 1). The 9,864,312 Series Pre-A Preferred Shares will be issued to the three shareholders once they have obtained all approval from PRC government and their capital contribution in the Company has been completed. Automatic conversion event was added for Series Angel, Series Pre-A and Series A preferred shares along with the issuance of Series A Preferred Shares on April 22, 2021, which is each series of Preferred Shares shall automatically be converted into Class A Ordinary Shares, at the then applicable conversion price upon (i) closing of a Qualified Initial Public Offering (“Qualified IPO”) or (ii) the written approval of the holders of a majority of each respective series of preferred shares. The Beneficial conversion feature (“BCF”) exists when the conversion price of the Series A Preferred Shares is lower than the fair value of the Class A Ordinary Shares at the commitment date, which is the issuance date of Series A Preferred Shares. No BCF was recognized for the Series A Preferred Shares as the fair value of the Class A Ordinary Shares at the commitment date was less than its most favorable conversion price. The fair value of the Company’s Class A Ordinary Shares was determined with the assistance of an independent third-party valuation firm. Additional Preferences of Preferred Shares after the Reorganization Additional Redemption Rights Upon the Reorganization, a new redemption event is added that Series Angel, Series Pre-A and Series A Preferred Shares are redeemable after the sixth anniversary of the issuance of Series A Preferred Shares (April 22, 2021) if a Qualified IPO or trade sale (the sales, through one or a series of transactions, of all or substantially all of the equity securities or assets or undertaking of the Company) does not occur. As it was not probable for the Redemption Event to happen before the reorganization, the Preferred Shares were not considered currently redeemable, and no accretions were made until the reorganization when the Qualified IPO and trade sale redemption term is added. The Group accretes changes in the redemption value from the date of reorganization and continue until such time to the redemption (6 years) date using interest method at a simple annual interest rate of 10%. The accretion will be recorded against retained earnings, or in the absence of retained earnings, by charges against additional paid-in capital. Once additional paid-in capital has been exhausted, additional charges should be recorded by increasing the accumulated deficit. The Preferred Shares are classified in mezzanine equity between the liabilities and the permanent equity on the consolidated balance sheets due to the conditional redemption right upon the occurrence of the redemption events which are beyond the Group’s control. As of December 31, 2020 and 2021, the mezzanine equities are $3,218 and $12,473, respectively. The change in the number of redeemable preferred shares for the years ended December 31, 2021, 2022 and 2023 is as follows: For the years ended December 31, 2021 2022 2023 (‘000) (‘000) (‘000) Number of redeemable preferred shares Opening balance 21,000 37,730 — Issuance of Series Angel Preferred Shares (1) — — — Conversion of Beijing SAI preferred shares due to reorganization (1) (21,000 ) — — Issuance of Series Angel Preferred Shares of the Company due to reorganization (2) 7,289 — — Issuance of Series Pre-A Preferred Shares of the Company due to reorganization (3) 13,974 — — Issuance of Series A Preferred Shares (4) 16,467 — — Conversion into Ordinary Shares (5) (37,730 ) — Ending balance 37,730 0 0 (1) The investment in a PRC entity is not presented in the form of single unit share, but the amount and percentage in paid-in capital of the entity. The number of shares presented is under the assumption that RMB1 ($0.15) is equal to 1 unit of share. (2) Series Angel Preferred Shares have a par value of $0.0001, with 7,288,630 shares authorized and issued. (3) Series Pre-A Preferred Shares have a par value of $0.0001, with 13,974,442 shares authorized. The number of Series Pre-A Preferred Shares issued during 2021 includes 4,110,130 Series Pre-A Preferred Shares issued at reorganization and 9,864,312 Series Pre-A Preferred Shares to be issued upon exercise of the warrants that were granted to three investors of Beijing SAI, as the exercise of these warrants were considered to be administrative procedures and the Company does not expect any circumstances under which those shares would not be issued. The $1.86 million for the exercise of the warrants is considered to be paid by the warrant holders at their Series Pre-A investment on Beijing SAI in September 2020. The administrative procedures for the exercise of the warrants have been completed and the funds were received by SAI on September 9, 2021, and the 9.8 million Series Pre-A Preferred Shares were issued on the same date. The Company considered the Series Pre-A Preferred Shares should be retrospectively stated in the financial statements as if they had been issued in September 2020 and were considered outstanding as of the balance sheet date. (4) Series A Preferred Shares has a par value of $0.0001, with 17,247,608 shares authorized and 16,466,767 shares issued.

Concentration of Risk	14. Concentration of Risk Credit risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable and due from related parties, stablecoin asset. As of December 31, 2023, all of the company’s cash and cash equivalents was held by major financial institutions located in PRC, Hong Kong, U.S., and Cayman.

For accounts receivable, the Company extends credit based on an evaluation of the customer’s financial condition, generally without requiring collateral or other security. Further, the Company reviews the recoverable amount of each individual receivable at each balance sheet date to ensure that adequate allowances are made for doubtful accounts. In this regard, the Company considers that the Company’s credit risk for accounts receivable is significantly reduced. For amount due from related parties, the Company provides advances to the officers for daily operation. For stablecoin asset, we monitor the market closely, to ensure the credit risk of stablecoin can be detected when occurred, and adequate impairment is made when necessary. The credit risk is mitigated by ongoing monitoring process of outstanding balance and timely collection when there is no immediate need for such advances.

Accounting Policies, by Policy

Accounting Policies, by Policy (Policies)	12 Months Ended
	Dec. 31, 2023
Summary of Significant Accounting Policies [Abstract]
Basis of presentation	a) Basis of presentation The Company’s consolidated financial statements are prepared and presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).
Principles of consolidation	b) Principles of consolidation The accompanying consolidated financial statements include the accounts of us and our subsidiaries, of which we are the primary beneficiary, from the dates they were acquired or incorporated. All inter-company transactions and balances have been eliminated upon consolidation.
Liquidity	c) Liquidity For the year ended December 31, 2023, the Company had a net loss of $6,120 and net cash outflow in operating activities of $3,125. As of December 31, 2023, our consolidated current assets exceeded our consolidated current liabilities by $11,565, we had cash and cash equivalents of $3,176, crypto assets and stablecoins assets of $6,790 , and accumulated deficit of $31,345. The Company believes its current cash and crypto assets on hand is sufficient to meet its operating and capital requirement for at least the next twelve months from the date these financial statements are issued.
Use of estimates	d) Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of these consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. The Company continually evaluates these estimates and assumptions based on the most recently available information, historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Significant accounting estimates reflected in the Company’s consolidated financial statements include but are not limited to estimates and judgments applied in determination of allowance for doubtful receivables, impairment losses for long-lived assets including intangible assets, impairment loss for cryptocurrencies, valuation allowance for deferred tax assets, provision for inventory, estimated forfeiture rate in calculation of share-based payment, estimated interest rate on calculation of operating lease. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from those estimates.
Foreign currency translation and transactions	e) Foreign currency translation and transactions Historically the Company’s principal country of operations is the PRC. The financial position and results of its operations are determined using RMB, the local currency, as the functional currency. The Company’s financial statements are reported using U.S. Dollars (“US$”, or “$”). The functional currency for the Company in Cayman Island is US$. Assets and liabilities are translated using the exchange rate at each balance sheet date. The consolidated statements of operations and comprehensive (loss)/income and cash flows denominated in foreign currency are translated at the average rate of exchange during the reporting period, and shareholders’ equity/(deficit) is translated at historical exchange rates. Adjustments resulting from the translation are recorded as a separate component of accumulated other comprehensive (loss)/income in shareholders’ equity. The value of RMB against US$ and other currencies may fluctuate and is affected by, among other things, changes in the PRC’s political and economic conditions. Any significant revaluation of RMB may materially affect the Company’s financial condition in terms of US$ reporting. The following table outlines the currency exchange rates that were used in creating the consolidated financial statements in this report: As of As of Balance sheet items, except for equity accounts 6.9646 7.0827 For the Year Ended December 31, 2021 2022 2023 Items in the consolidated statements of operations and comprehensive (loss)/income, and cash flows 6.4000 6.7190 7.0422 No representation is intended to imply that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate stated above, or at any other rate.
Cash and cash equivalents	f) Cash and cash equivalents Cash and cash equivalents consist of bank deposits, which are unrestricted as to withdrawal and use. The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents.
Accounts receivable	g) Accounts receivable The Company records accounts receivable at net realizable value consisting of the carrying amount less an allowance for uncollectible accounts as needed. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on aging data, historical collection experience, customer specific facts and economic conditions. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of December 31, 2023 and 2022, the Company did not record any allowances for doubtful accounts against its accounts receivable.
Inventories	h) Inventories Inventories, consisting of digital mining cabinets and related accessories for the production purpose, are stated at the lower of cost or net realizable value. The cost of inventory is determined using the identified cost of the specific item. Inventory is written down for damaged and slow-moving crypto asset mining machines, which is dependent upon factors such as historical and forecasted consumer demand and expected selling price. Write downs are recorded in cost of revenues in the consolidated statements of operations and comprehensive (loss)/income. For the year ended December 31, 2023 and 2022, the Company did not recognize any write down on inventories.
Crypto assets	i) Crypto assets Crypto assets purchased are recorded at cost and Crypto assets (mainly bitcoin) awarded to the company though its mining activities are accounted for in connection with the Company’s revenue recognition policy. Crypto assets (bitcoin) are included in current and other assets in the accompanying Consolidated Balance Sheets due to the Company’s ability to sell bitcoin in a highly liquid marketplace and the selling of bitcoin to fund operating expenses to support operations. Crypto assets held are accounted for as intangible assets with indefinite useful lives. Crypto assets are measured on a first-in-first-out (“FIFO”) in order to more accurately reflect the disposition of company’s crypto assets. ASC 350-60 provides guidance on classifying proceeds from bitcoin and concludes that bitcoin converted nearly immediately into cash would qualify as cash flows from operating activities. All other sales would qualify as investing activities. The Company evaluates its sales of bitcoin and will record crypto assets sold nearly immediately as operating cash flows and the remainder will be recorded as investing activities. During year ended December 31, 2023, all proceeds from bitcoin sales were classified as investing activities. As a result of adopting ASC 350-60 on October 1, 2023, crypto assets are measured at fair value as of each reporting period. The fair value is measured using the period-end closing crypto assets price from its principal market in accordance with ASC 820, Fair Value Measurement. Effective January 1, 2023, the Company early adopted ASU 2023-08, which requires entities to measure crypto assets at fair value with changes recognized in the Consolidated Statement of Operations and Comprehensive Income (Loss) each reporting period. The Company’s crypto assets are within the scope of ASU 2023-08 and the transition guidance requires a cumulative-effect adjustment as of the beginning of the current fiscal year for any difference between the carrying amount of the Company’s crypto assets and fair value. As a result of the Company’s early adoption of ASU 2023-08, the Company recorded a $79 increase to crypto assets and a $79 increase to accumulated deficit on the Consolidated Balance Sheets as of the beginning of the fiscal year ended December 31, 2023. Prior to the adoption of ASU 2023-08, crypto assets were accounted for as intangible assets with indefinite useful lives and are recorded at cost less impairment in accordance with ASC 350 – Intangibles-Goodwill and Other Fair Value Measurement Crypto assets generated from the crypto assets mining business and the mining pool business as well as the crypto assets distributed to mining pool participants are included within operating activities in the accompanying consolidated statements of cash flows. The sales of crypto assets are included within investing activities in the accompanying consolidated statements of cash flows and any realized gains or losses from such sales are included in gain or loss of disposal of crypto assets in the consolidated statements of operations and comprehensive (loss)/income.
Stablecoin assets	j) Stablecoin assets Stablecoin is included in current assets in the accompanying consolidated balance sheets. The Company holds positions in the stablecoins USD Coin (USDC), which are crypto assets, but are considered a financial instrument in accordance with ASC Topic 825. These stablecoins are recognized in the consolidated balance sheets as investment recognized at fair value.
Property and equipment, net	k) Property and equipment, net The Company records plant not yet placed into service as construction in progress. Once the plant is completed and operational, the construction in progress is reclassified to “Plant” and depreciated over the estimated useful life. The Company’s property and equipment are recorded at cost less accumulated depreciation and impairment loss, if any. Depreciation is calculated on the straight-line method after taking into account their respective estimated residual values over the following estimated useful lives: Item Useful lives Radio of Furniture, fixture and other equipment 3 years 5 % Electronic equipment 3 – 5 years 5 % Plant Shorter of useful life or lease term 0 % When property and equipment are retired or otherwise disposed of, resulting gain or loss is included in net income in the period of disposition. For the year ended December 31, 2023, 2022 and 2021, the Company recognized $402, $718 and$317 on loss from disposal of property and equipment, net.
Intangible assets, net	l) Intangible assets, net The Company’s intangible assets primarily consisted of purchased software used for specific crypto asset mining machines to increase the computing power or reduce power consumption. The software is initially recorded at purchased cost and amortized on a straight-line basis over the estimated useful lives of 3 years. , the intangible asset has been amortized to 0.
Construction in process	m) Construction in process Direct costs that are related to the construction of equipment and incurred in connection with bringing the assets to their intended use are capitalized as construction in process. Construction in process is transferred to specific plants and equipment items and the depreciation of these assets commences when the assets are ready for their intended use.
Impairment of long-lived assets	n) Impairment of long-lived assets All long-lived assets, which include tangible long-lived assets and intangible long-lived assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of the asset to the estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recognized for the difference between the carrying amount of the asset and its fair value. For the year ended December 31, 2023, 2022 and 2021, the Company recognized $138, $912 and nil
Fair value of financial instruments	o) Fair value of financial instruments The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable and stablecoin. The carrying values of these financial instruments’ approximate fair values due to their short term in nature. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This topic also establishes a fair value hierarchy which requires classification based on observable and unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter.
Revenue recognition	p) Revenue recognition In accordance with ASC Topic 606, revenues are recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. In determining when and how much revenue is recognized from contracts with customers, the Company performs the following five-step analysis: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; (5) recognize revenue when (or as) the entity satisfies a performance obligation. The Company assesses its revenue arrangements against specific criteria in order to determine if it is acting as principal or agent. Sales of products Revenue generated from sales of products occurs for the sales of crypto asset mining machines to end customers. The Company presents the revenue generated from its product sales on a gross basis as the Company acts as the principal and has control of the goods and has the ability to direct the use of goods to obtain substantially all the benefits. In making this determination, the Company also assesses whether it is primarily obligated in these transactions, is subject to inventory risk, has latitude in establishing prices, or has met several but not all of these indicators. Revenues are measured as the amount of consideration the Company expects to receive in exchange for transferring control of products to customers. Consideration from product sales is recorded net of value-added tax, and there is generally no other performance obligation other than the delivery of products. Proceeds from product sales are recognized as revenue at the point in time when the receipt of product is confirmed by the customer. Hosting service Revenues generated from hosting service is earned by the Company to perform hosting service and daily maintenance of servers for customers throughout the contractual period. The single performance obligation is to provide an environment for the servers to operate continuously which is satisfied over time. Such hosting service revenue is recognized over time as the performance obligation is satisfied over the term of the contracts with customers. Mining pool services The Company operates its mining pool, Sai.plus, to enable providers of computing power (“pool participants”) to participate in crypto-mining activities in an efficient manner in the blockchain network, in exchange for a fee (“pool operator fee”) for its coordination efforts as the pool operator. The Company receives all the mining rewards in its own name, and then allocates mining rewards to each pool participant net of the pool operator fees based on the sharing mechanism predetermined. The mining rewards include the block rewards and the transaction verification fees related to the transactions included in the block. The Company considers itself the principal in transactions with the blockchain networks and recognizes the mining pool revenue on a gross basis. The performance obligation is to create or validate each block. Revenue is recognized at the point when the block creation or validation is complete, and the Company has received the rewards. Revenue is measured at the fair value of rewards upon receipt, which is not materially different than the fair value at contract inception. The Company considers itself the principal in transactions with the blockchain networks as it coordinates all the computing power within the mining pool, delivers such aggregated computing power to the blockchain network, collects centrally all mining rewards and distributes them in accordance with the predetermined sharing mechanisms. The Company has control over the pool participants’ computing power. Although the pool participants can enter and exit the pool at will and deploy the qualifying types of mining machines at the choices of the pool participants, during the mining process, the Company dictates the tasks and the participants’ mining machines merely follow the allocation prescribed by the Company. As a result, the Company is primarily responsible for fulfilling the promise to provide the specified service. Further, under existing sharing mechanisms, the Company is exposed to the risk that actual block rewards may differ from expected rewards, therefore, bears the inventory risk before the specified service has been transferred to a customer. The Company provides mining pool services under Sai.plus. Mining Revenue. The Company have
Income taxes	q) Income taxes The Company follows the guidance of ASC Topic 740 “Income taxes” and uses liability method to account for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Company records a valuation allowance to offset deferred tax assets, if based on the weight of available evidence, it is more-likely-than-not that the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in statement of operations and comprehensive (loss)/income in the period that includes the enactment date.
Uncertain tax positions	r) Uncertain tax positions The Company uses a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As a result, the impact of an uncertain income tax position is recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest on non-payment of income taxes under requirement by tax law and penalties associated with tax positions when a tax position does not meet the minimum statutory threshold to avoid payment of penalties recognized, if any, will be classified as a component of the provisions for income taxes. The tax returns of the Company’s Hong Kong and PRC subsidiaries and VIE are subject to examination by the relevant local tax authorities. According to the Departmental Interpretation and Practice Notes No.11 (Revised) (“DIPN11”) of the Hong Kong Inland Revenue Ordinance (the “HK tax laws”), an investigation normally covers the six years of the assessment prior to the year of the assessment in which the investigation commences. In the case of fraud and willful evasion, the investigation is extended to cover ten years of assessment. According to the PRC Tax Administration and Collection Law, the statute of limitations is three years if the underpayment of taxes is due to computational errors made by the taxpayer or the withholding agent. The statute of limitations is extended to five years under special circumstances, where the underpayment of taxes is more than RMB100,000. In the case of transfer pricing issues, the statute of limitation is ten years. There is no statute of limitation in the case of tax evasion. For the year ended December 31 2023, 2022 and 2021, the Company did not have any material interest or penalties associated with tax positions. The Company did not have any significant unrecognized uncertain tax positions as of December 31, 2023 and 2022. The Company does not expect that its assessment regarding unrecognized tax positions will materially change over the next 12 months.
Segment reporting	s) Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker (the “CODM”), which is comprised of certain members of the Company’s management team. Consequently, the Company has determined that it has two reportable operating segments. In addition, the Company’s chief operating decision maker makes resource allocation decisions and assesses performance based on the different business operating results instead of the geographic location operating results. Therefore, no geographical segments are presented.
Earnings per share	t) Earnings per share Earnings (loss) per share is computed in accordance with ASC 260. The two-class method is used for computing earnings per share in the event the Company has net income available for distribution. Under the two-class method, net income is allocated between ordinary shares and participating securities based on dividends declared and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. Series Angel and Series Pre-A Preferred Shares issued by the Company qualified as participating securities because they have the same participating rights on the earnings of the Company as ordinary shares on an as-converted basis after the preferred shareholders receive non-cumulative annual dividends up to 100% of the original issue price for each of the preferred shares. Basic earnings (loss) per ordinary share is computed by dividing net income/(loss) attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the period. Diluted earnings/(loss) per share is calculated by dividing net income/(loss) attributable to ordinary shareholders by the weighted average number of ordinary and potential ordinary shares outstanding during the period. Potential ordinary shares include ordinary shares issuable upon the conversion of the preferred shares using the if-converted method. Potential ordinary shares are not included in the denominator of the diluted earnings per share calculation when inclusion of such shares would be anti-dilutive or in the case of contingently issuable shares that all necessary conditions for issuance have not been satisfied. For the year ended December 31 2023, 2022 and 2021, there were no dilutive shares.
Share based compensation	u) Share based compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the cost over the period the employee is required to provide service in exchange for the award, which generally is the vesting period. The Company recognizes compensation cost for an award with only service conditions that has a graded vesting schedule on a straight-line basis over the requisite service period for the entire award, net of estimated forfeitures, provided that the cumulative amount of compensation cost recognized at any date at least equals the portion of the grant-date value of such award that is vested at that date. Forfeiture rates are estimated based on historical and future expectations of employee turnover rates.
Commitments and contingencies	v) Commitments and contingencies The Company accrues estimated losses from loss contingencies by a charge to income when information available before financial statements are issued or are available to be issued indicates that it is probable that an asset had been impaired, or a liability had been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred. As of December 31, 2023 and 2022, there were no contingent liabilities relating to litigations against the Company.
Leases	w) Leases In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. The amendments in this ASU requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities.
Reclassification of crypto assets and stablecoins	x) Reclassification of assets and stablecoins As Tether reserves the right under its user agreement to redeem USDT by in-kind redemptions of other assets it holds in its reserves and as Tether has held precious metals and other non-financial assets in its reserves, it does not appear that USDT meets the definition of a financial instrument under ASC 825-10-20. The Company reclassified USDT, amounting $ as of December 31, 2022, from stable coins to assets. The reclassification had no impact on net assets as of December 31, 2022, and revenues and net loss for the year ended December 31, 2022.
