SEC proposal would let blockchain serve as the legal shareholder register
The transfer-agent rule update could make an onchain ledger the “master security file” for tokenized securities, with comments due in early November.
The Securities and Exchange Commission has proposed modernizing transfer-agent rules to explicitly allow electronic databases, including blockchain ledgers, to serve as the official record of securities ownership. If adopted, the change could let tokenized securities treat the onchain ledger as the legally recognized shareholder register instead of maintaining a parallel offchain record.
Key Takeaways
- The Securities and Exchange Commission proposed updating transfer-agent rules so electronic databases, including blockchain ledgers, can be the official record of securities ownership.
- The draft would allow tokenized securities to use a blockchain as the authoritative “master security file,” potentially eliminating today’s duplicate onchain and offchain shareholder records.
- The framework keeps securities-law constraints in place, meaning identity checks and transfer restrictions can still be required and embedded in the token.
- A 60-day public comment period is open and scheduled to end in early November.
SEC Transfer-Agent Proposal Puts Blockchain on Track to Be the Legal Shareholder Register
The Securities and Exchange Commission (SEC) has put forward a proposal to overhaul transfer-agent rules that date back roughly five decades, and the key modernization is explicit: the agency would permit electronic databases, including blockchain ledgers, to serve as the official record of securities ownership.
That matters because transfer agents are the regulated recordkeepers that maintain the shareholder register and administer changes to ownership, and the “master security file” or “master securityholder file” is the system of record that legally defines who owns what. Under the proposal, a blockchain ledger would not just be a convenient mirror of ownership data. It could be the legally recognized register itself.
Joris Delanoue, chief executive of Fairmint, an SEC-registered onchain transfer agent, framed the shift as a straight line in recordkeeping technology. “The master securityholder file used to be paper in a filing cabinet. Today it is a database. The proposal recognizes that blockchain can be that database, not merely a copy of it.”
Why the Two-Ledger Problem Matters for Tokenized Securities When Things Break
Tokenized securities often run with two ledgers that can disagree at the worst possible time: the onchain token ledger that reflects token balances and transfers, and a separate official shareholder register that remains the legal source of truth. When there is a mismatch, the legal system defaults to the offchain record, even if the blockchain ledger is more current.
In calm markets, that split reads like operational annoyance and cost. Every transfer can create a reconciliation step, and every reconciliation step creates a place for latency, human error, or policy drift between the token logic and the official register.
In stress, the same structure becomes a legal-finality problem. Eli Cohen, chief legal officer at fund tokenization firm Centrifuge, argued the current setup is more than inefficiency because it can turn into a dispute over which record controls ownership when counterparties are already fighting over the scraps. “If there was an insolvency or a bankruptcy, there would be just a mess,” Cohen said.
Cohen described the SEC’s proposal as a path to collapsing that two-step structure into “a one-step process,” with the blockchain itself serving as the master security file. For tokenized equities and other real-world assets, that is the difference between an onchain transfer being economically meaningful and it being legally final.
Compliance Doesn’t Disappear: Transfer Restrictions, Identity Checks, and the Full Transfer-Agent Function
The proposal is not a permissionless pivot. Even if a public blockchain hosts the ownership record, securities rules still govern who can own the asset and how it can be transferred, and Delanoue said those controls can be built into the token itself. The onchain ledger can become the register without turning tokenized securities into unrestricted bearer instruments.
The other constraint is operational, and it is where a lot of tokenization narratives tend to thin out. The SEC’s approach still assumes the transfer-agent function exists in full, including the messy edge cases that show up in real ownership: shareholder deaths, inheritance, legal notices, mailing addresses, ownership restrictions, and fixing records when something goes wrong.
Some of that work remains stubbornly physical. Delanoue pointed to the mechanics of handling incoming mail, where firms must receive, open, identify, and act on mailed documents under prescribed procedures. He said the current processing window is 3–5 days, and the proposal could reduce it to 1 day, though that specific change is not yet final and would depend on the rule’s adopted form.
Delanoue’s warning for would-be digital transfer agents was blunt. “There is no more free lunch,” he said. “If you want to maintain the official ownership record, you have to operate the full transfer-agent function.” Cohen added that the compliance and administrative burden may push some firms to rely on established providers for parts of the process rather than trying to run the entire stack themselves.
The SEC transfer-agent proposal legitimizes Milestones Ahead
The immediate tradable signal is procedural, not technological. The SEC has opened a 60-day public comment period that is scheduled to end in early November, and the content of those comment letters will shape whether the agency permits blockchain-ledger recordkeeping broadly or narrows it behind specific operational and control requirements for digital transfer agents.
After the comment window closes, the next meaningful indicator will be whether the SEC signals a clear path to adoption and implementation, or whether it requests additional changes that effectively reintroduce a dual-record model through compliance conditions.
Industry-side, the practical tell will be whether tokenization platforms and transfer-agent firms begin announcing plans to move from dual-record setups to a single onchain “master security file” model, explicitly contingent on the final rule language.
My Take: This Is a Plumbing Upgrade for RWAs, Not a Deregulation Moment
The filing is being read in some corners as a green light for tokenized securities, and that interpretation skips the part that actually does the work. The proposal is about legal finality and recordkeeping architecture, where the threshold that matters is whether the blockchain ledger can be the authoritative shareholder register without a second offchain book that lawyers will default to when a dispute hits.
The real test is whether the final rule keeps the onchain ledger as the master security file while still forcing transfer agents to run the full compliance and admin stack Delanoue described. If that holds, the setup starts to look structural rather than narrative-driven because it reduces reconciliation risk without pretending securities can become permissionless, and it makes “who can operate the transfer-agent function” the new moat for tokenized RWAs.
