SEC Seeks to Allow Blockchain as Official Ledger for Tokenized Securities

The U.S. Securities and Exchange Commission (SEC) is seeking to modernize decades-old rules governing transfer agents, opening the door for blockchain-based ledgers to serve as official records of securities ownership.

The proposal, announced on September 1, 2026, would update a framework that has not been substantially revised since the late 1970s and early 1980s. It aims to reflect the growing use of electronic recordkeeping and blockchain technology across U.S. securities markets.

The move could have significant implications for tokenized securities, where ownership records are often divided between an on-chain ledger and a separate database maintained by an issuer or registered transfer agent.

SEC targets the dual-record model for tokenized securities

Under existing tokenization structures, the blockchain transaction does not necessarily constitute the legally controlling record of ownership.

Instead, a token may record a transfer on-chain while a transfer agent maintains the official shareholder register off-chain. This creates two connected but separate records that may need to be reconciled after transactions.

The SEC's proposal could allow a qualifying distributed ledger to form all or part of the official Master Securityholder File maintained by a registered transfer agent. In practice, this could reduce the need to reproduce every blockchain transaction in a separate database.

This approach would build on an earlier SEC staff position, which stated that a registered transfer agent could use distributed ledger technology as its official ownership record, provided it continued to satisfy existing recordkeeping, reporting, safeguarding and other regulatory requirements.

Blockchain could become the primary ownership record

The potential shift is important because it could bring the digital representation of a security and its legally recognized ownership record closer together.

For tokenized securities, that could mean a transfer recorded on a blockchain would no longer have to be treated simply as a digital reflection of a separate off-chain transaction.

However, the proposal does not give every blockchain or token structure automatic recognition. Transfer agents would still have to comply with requirements covering record accuracy, security, reporting, safeguarding and regulatory oversight.

The SEC is also seeking feedback on how its rules should apply when ownership records exist entirely on a blockchain that is not controlled exclusively by the transfer agent.

Tokenized securities would remain subject to investor protections

Recognizing a blockchain as an official ownership record would not remove the legal requirements attached to the underlying security.

Tokenized shares could still be subject to investor eligibility requirements, transfer restrictions, identity checks and other controls. Smart contracts could also be used to prevent transfers when a wallet or investor does not satisfy the conditions attached to the security.

The distinction is particularly important because not every stock-related token gives its holder direct ownership of the underlying shares. Some products may provide economic exposure without placing the investor on the issuer's official shareholder register.

The SEC has previously distinguished between issuer-sponsored tokenized securities, where the blockchain can form part of the master securityholder file, and third-party products where the token does not itself represent the underlying security's ownership record.

Transfer agents would retain key legal responsibilities

Blockchain adoption would not eliminate the role of transfer agents.

These entities would continue to maintain accurate ownership records and handle actions that cannot simply be executed through a token transfer. Their responsibilities can include processing ownership changes, maintaining issuer records, addressing legal orders and handling situations such as lost securityholder information.

The SEC's proposed framework therefore focuses more on modernizing the technology used by transfer agents than removing their regulatory obligations. The commission is seeking to ensure that blockchain-based records remain accessible, accurate, secure and capable of supporting legally required changes.

This could allow blockchain infrastructure to handle more of the administrative process while keeping regulatory responsibility with the registered transfer agent.

SEC proposal could streamline tokenized securities settlement

One potential benefit is reducing the need to reconcile separate ownership databases after each transaction.

If the blockchain itself becomes part of the authoritative ownership record, transaction data and shareholder information could be brought closer together. This could help reduce operational duplication and potentially shorten settlement and administrative processes.

At the same time, issuers and transfer agents would still need mechanisms to correct errors, comply with court orders, protect investor information and restore access when investors lose control of their wallets.

The SEC's proposal specifically asks how blockchain-based records should meet requirements related to integrity, accessibility and immutability, highlighting that operational safeguards remain central to the framework.

Institutional tokenization moves beyond pilot projects

The SEC's proposal comes as financial institutions increasingly move from experimenting with tokenization toward building production-ready infrastructure.

For example, Cosmos launched a partner network of 17 companies in September to help banks implement tokenized deposits and digital asset projects. The network brings together providers covering custody, compliance, security and blockchain infrastructure.

Wells Fargo is also preparing to roll out tokenized deposits for corporate and commercial clients in the fall of 2026, initially focusing on a limited U.S. dollar-to-pound use case before expanding to additional clients, countries and currencies.

These developments point to a broader shift in which financial institutions are beginning to focus less on whether tokenization works in theory and more on the infrastructure, compliance and operational standards needed to deploy it at scale.

Stock tokens highlight the difference between exposure and ownership

The debate over what constitutes genuine ownership has also become more visible as trading platforms introduce tokens linked to public companies.

Robinhood CEO Vlad Tenev recently defended the platform's AMC-related stock tokens after AMC CEO Adam Aron challenged their issuance without the company's approval. Robinhood argued that third-party products referencing publicly traded shares do not automatically require issuer consent.

That dispute illustrates why the SEC's transfer-agent proposal matters. A token that merely provides exposure to a stock is structurally different from an issuer-backed tokenized security whose ownership is recorded through an authorized transfer agent.

If blockchain records gain clearer regulatory recognition, the distinction between these models could become increasingly important for issuers, investors and trading platforms.

SEC opens the door to on-chain securities ownership

The SEC's proposal represents a significant step toward aligning U.S. securities infrastructure with the technology already being used to issue and transfer digital assets.

Rather than creating a separate regulatory system for blockchain-based securities, the commission is seeking to adapt the existing transfer-agent framework to accommodate electronic and distributed-ledger records.

Public comments are due 60 days after publication in the Federal Register, meaning the proposal could still be modified before the SEC considers a final rule.

Why the proposal matters

The importance of the SEC's proposal goes beyond simply allowing transfer agents to use blockchain technology. It could determine whether tokenized securities can eventually operate on infrastructure where the digital record and the legally recognized ownership record are effectively the same.

That distinction has been one of the structural limitations of tokenization: putting an asset on a blockchain does not automatically make the blockchain the authority over ownership. If the SEC succeeds in creating a framework that allows the two records to converge without weakening investor protections, tokenization could move from an experimental technology layer toward a more integrated part of U.S. capital markets.

The real test, however, will be whether on-chain ownership can deliver faster and more efficient settlement while still handling the legal exceptions, investor protections and regulatory controls that traditional transfer agents manage today. In that sense, the proposal is less about replacing transfer agents with blockchain and more about determining whether blockchain can become part of the regulated infrastructure through which securities ownership is officially recognized.
