The U.S. Securities and Exchange Commission is asking whether a blockchain wallet could eventually replace part of the traditional identity and contact information maintained for registered shareholders, as tokenized securities force regulators to reconsider rules built around paper records and postal addresses.
The question appears inside the SEC’s sweeping September 1 proposal to overhaul transfer-agent regulations for the first time in decades. Under the proposed rules, registered transfer agents could use a blockchain or other distributed ledger as the official master securityholder file, or as a component of that record.
That represents a significant change for tokenized securities because the blockchain could form part of the legally relevant ownership infrastructure rather than merely operating as a parallel technological record.
But it creates a basic regulatory question: if an investor holds securities through a blockchain address, what information does a transfer agent actually need to identify and contact that shareholder?
Wallet Addresses Enter the Official Shareholder Record
The SEC proposes updating the information that transfer agents maintain as “position detail” for each registered securityholder. The record would include the shareholder’s full name plus other identifying, titling or formatting information necessary to accurately identify the account. For tokenized securities, the SEC specifically gives a digital wallet address as an example of that additional identifying information.
The regulator separately proposes requiring sufficient contact information to deliver shareholder communications, dividends, payments and legal notices. As currently drafted, that information must include at least a physical mailing address. Phone numbers, email addresses and blockchain wallet addresses could be maintained in addition to it.
But the SEC is explicitly asking whether that requirement should go further. One of the proposal’s questions asks whether the rules should omit the minimum requirement to collect a physical mailing address. It asks whether transfer agents should instead follow a principles-based standard requiring only information reasonably necessary to establish contact with the shareholder.
The Commission then specifically asks whether an email address, telephone number or digital wallet could satisfy an alternative minimum requirement.
Tokenized Stocks Challenge Decades-Old Identity Rules
The distinction between identification and contact information matters. A wallet address can identify a blockchain account with extraordinary precision, but it does not inherently reveal the legal identity of the person controlling it. That creates complications involving shareholder communications, sanctions compliance, lost investors, inheritance, voting rights and recovery when access credentials are lost.
The SEC therefore is not proposing anonymous shareholder registers. A registered transfer agent would remain responsible for maintaining an accurate master securityholder file and connecting blockchain positions with the information required under federal securities rules.
The proposal nevertheless shows how substantially tokenization could alter traditional market infrastructure. The SEC specifically asks how transfer agents should associate onchain records — including wallet addresses, quantities of securities and issuance dates — with offchain information such as shareholder names and addresses.
It also asks how regulators should handle records existing entirely on blockchains not exclusively controlled by the transfer agent.
The Commission is considering similar modernization for “lost securityholder” requirements. In discussing an alternative approach, the SEC notes that allowing communication methods other than physical addresses could support transfers of tokenized securities without requiring collection of a physical address before a transfer is enabled.
These questions have practical implications beyond crypto-native securities. NYSE, Nasdaq and major financial institutions are developing infrastructure intended to move conventional securities onto blockchain rails, while registered transfer agents including Securitize and Superstate already support tokenized assets.
If blockchain records ultimately become authoritative shareholder registers, securities ownership could begin to resemble crypto infrastructure technically while remaining attached to regulated identities legally. The SEC’s proposal stops short of deciding exactly where that line should sit.
For now, a wallet address can supplement the shareholder’s identity and contact record but does not replace the required physical address. The Commission is asking whether that should change.
Its answer could determine whether the future shareholder account looks primarily like today’s brokerage record with a wallet attached — or a blockchain wallet with regulated identity information attached behind it.
