SEC Proposes Crypto Custody Rules: What It Means for Tokenized Real Estate

On October 1, 2026, the Securities and Exchange Commission proposed a custody framework for registered investment advisers and regulated funds that hold crypto assets. It is a proposal, not a final rule. The SEC has opened a 60-day comment period, and the text may change before anything is adopted.

For anyone tokenizing private real estate, the proposal raises one question that matters more than the rest. This note summarizes what was proposed, explains that question, and sets out what sponsors and advisers may want to consider while the comment period runs.

What the proposal would do

• Custody by permitted custodians. Advisers could self-custody crypto assets only when no permitted custodian is available. An adviser relying on that path would need to make a written determination each quarter and apply additional safeguards.
• State trust companies. State-chartered trust companies could act as custodians under the framework.
• Blockchain recordkeeping. Blockchain records could be used for recordkeeping purposes, subject to conditions.
• Comment period. The public has 60 days to comment. Any final rule would come later and could differ from the proposal.

The open question for real estate tokens

A token representing an interest in a private real estate offering is a security first and a blockchain record second. Its transfers are restricted, and it can only be held by investors who qualify under the offering's exemption.

The open question is whether transfer-restricted tokenized private securities are “crypto assets” under the proposed rule, or whether they remain privately offered securities under the existing custody framework. The answer would shape how advisers hold these interests on behalf of clients. Until a final rule is adopted, sponsors and advisers should plan for either outcome.

Why Ioniqx is positioned for either outcome

Ioniqx was built around the assumption that a tokenized interest must behave like the restricted security it represents. Three things are true of the platform today:

• Every transfer is checked on-chain. Using Token-2022 transfer hooks, each transfer is tested against compliance rules the issuer controls before it settles. A transfer that fails the rules does not happen.
• Only approved wallets can hold tokens. A wallet that has not been approved for the offering cannot receive them.
• The issuer's register is the authoritative ownership record. Ownership does not depend on who holds a private key; the register is the record of who owns what.

If these tokens are treated as crypto assets, those controls give an adviser and its custodian a clear, verifiable picture of who can hold the asset and how it can move. If they are treated as privately offered securities, the ownership record already looks like that of a conventional private offering: an issuer-maintained register.

Two capabilities advisers are likely to ask about are on our roadmap rather than available today: support for holding tokens in custodial wallets, and reporting exports designed for advisers.

What this means for sponsors

Registered investment advisers are a potential new investor channel. If a final rule gives advisers a clearer path to holding tokenized interests for their clients, sponsors whose offerings already enforce transfer restrictions and maintain a clean register will be better prepared to work with them.

What this means for RIAs

Questions worth asking any tokenization platform:

• What is the authoritative ownership record: the blockchain, the issuer's register, or the platform's database?
• Are transfer restrictions enforced on-chain before a transfer settles, or reviewed after the fact?
• Who approves the wallets that can hold a token, and how is that approval revoked?
• Can tokens be held through a custodian's wallet today, or is that planned?
• What records and reports can you export for your books and examinations?
• How would the platform's tokens be treated if they are classified as crypto assets, and what changes if they are not?
