                       File Nos. 333-270872 and 811-21429

Dear Mr. Anderson:

       On March 27, 2023, you filed a registration statement on Form S-6 for
SmartTrust 613
(Healthcare Innovations Trust II, Series 1 and Technology Revolution Trust II,
Series 1) (the
   Trust   ), a unit investment trust. We have reviewed the registration
statement, and have provided
our comments below. For convenience, we generally organized our comments using
headings,
defined terms, and page numbers from the registration statement. Where a
comment is made in
one location, it is applicable to all similar disclosure appearing elsewhere in
the registration
statement.

Healthcare Innovations Trust II

PROSPECTUS (PART A)
Investment Objective (page A-3)
1. Please revise the Trust   s investment objective to clarify that total
return also includes income.
Principal Investment Strategy (pages A-3     A-5)
2. On page A-4, the last sentence of the fourth paragraph states that    [b]oth
of these eligibility
   criteria are subject to a 10% buffer for constituents in the Syntax US
Medical Innovation Index
   prior to reconstitution.    Please revise this sentence to clarify the
disclosure.
3. On page A-5, the first sentence of the first full paragraph states that
Syntax US Medical
   Innovation Index is rebalanced quarterly and the second sentence of this
paragraph states that
   such index is reconstituted semi-annually. Please disclose the difference
between rebalance
   and reconstitution of the index.
4. On page A-5, the third sentence of the first full paragraph states that
Syntax US Medical
   Innovation Index eligibility criteria is determined as of the snapshot date.
Inasmuch as this
   suggests that the index   s eligibility criteria can change on each snapshot
date, tell us whether
   or not the disclosure in this section describing the index   s eligibility
criteria will remain the
   same as disclosed here at the Security Selection Date. We may have more
comments after
   reviewing your response.

5. On page A-5, the sixth sentence of the first full paragraph states that
additions of index
   constituents are generally not made at the entity level in the rebalancing
but may be made at
   the listing level. Please disclose the meaning of, and difference between,
 entity level    and
      listing level   .
Principal Risk Considerations (pages A-5     A-6)
6. On page A-6, the second bulleted risk states that the Trust is considered to
be concentrated in
   securities issued by companies in the health care sector. Please also
disclose this statement in
   the Principal Investment Strategy section.
Technology Revolution Trust II
Principal Investment Strategy (pages A-11     A-13)
7. Please disclose in bold that (1) the Trust will not invest directly or
indirectly (e.g., through
   bitcoin derivatives) in cryptocurrencies and (2) because the Trust does not
invest directly or
   indirectly in cryptocurrencies, the Trust is not expected to track the price
movements of any
   cryptocurrency.
8. On page A-11, the second sentence of the last paragraph states that the
sponsor defines
   companies engaged in revolutionary technologies to be companies that are
principally engaged
   in or derive significant revenues from businesses in, among other things,
blockchain. Please
   provide us with a list of the Trust   s portfolio securities that would be
principally engaged in or
   derive significant revenues from businesses in blockchain. We may have more
comments after
   reviewing your response.
9. On page A-11, the second sentence of the last paragraph states that the
sponsor defines
   companies engaged in revolutionary technologies to be companies that are
principally engaged
   in or derive significant revenues from businesses in, among other things,
banking, insurance
   and investment technology   . Please replace the term    banking, insurance
and investment
   technology    with a term that clarifies that this business category does
not include banks and
   insurance companies (e.g., financial investment technology).
10. On page A-12, the first full sentence states that the Trust may invest in
securities of foreign
    issuers, including companies in emerging markets. If the Trust   s
portfolio will include
    significant investments in a particular country or region, please identify
the country or region
    here and disclose the specific risks of that country or region in the
Principal Risk
    Considerations section.
11. On page A-12, the second full paragraph states that candidates of the
Syntax North American
    Technology Revolution Index are identified using data showing that their
issuing companies
    derive at least 50% of their revenues from one or more business segments,
including
    blockchain (described as including companies that utilize blockchain
technology for payment
    processing, recordkeeping and other applications). Inasmuch as the first
full sentence on page
    B-5 states that blockchain technology is not a product or service that
provides identifiable
    revenue for companies that implement or otherwise use it, please explain to
us how a company
    that utilizes blockchain technology for the purposes identified in the
first bullet would derive
    at least 50% of its revenues from blockchain technology and therefore be
included in the
    Syntax North American Technology Revolution Index. Please note that, in the
staff   s view, it

      would not be appropriate to categorize a company whose sole tie to
blockchain is to use it to
      accept cryptocurrency payments as in the blockchain business.
12. Please apply comments 2 through 5 to the same disclosure that is included
on page A-13.
PART B
Principal Risk Considerations     Risks Associated with Blockchain;
Cybersecurity; Internet
of Things; Banking, Insurance, and Investment Technology; High-Performance

    remove one set of these sentences.
