SEC Opens Five-Year Path for Tokenized U.S. Stocks on Public Blockchains

The U.S. Securities and Exchange Commission has approved a five-year sandbox for qualifying venues to trade tokenized U.S. stocks on public blockchains without registering as full national securities exchanges. The framework could give blockchain networks, including Solana, a role in the infrastructure supporting regulated equity markets, although access to the venues will remain permissioned.

A Regulated Test for On-Chain Equities

The exemption creates a temporary category called Tokenized Securities Venues, or TSVs. These platforms can facilitate trading in eligible tokenized stocks through smart contracts and liquidity pools rather than relying exclusively on traditional exchange order books.

The tokens must represent genuine ownership of the underlying shares. Holders must receive the same voting, dividend and other rights as traditional shareholders, and a tokenized stock must halt trading if its primary-market counterpart is halted. Synthetic instruments that only track stock prices are excluded from the framework.

• The sandbox lasts five years.
• Venues must use public, auditable software deployed on a public, permissionless blockchain.
• Access to each venue remains permissioned for approved investors and market participants.
• The exemption does not authorize leverage or lending.

The structure resembles DeFi in its use of automated market makers and liquidity pools, but it retains institutional controls around who can participate and which securities may be listed.

Tight Limits and Issuer Control

The SEC is limiting the scale of the experiment. A venue can tokenize as many as 75 of the most liquid stocks while handling no more than 0.25% of their average daily trading volume. For a second tier of stocks, the limits rise to 250 names and 2.5% of average daily volume.

For example, a venue could theoretically process roughly 100,000 tokenized Tesla shares per day, equivalent to about $36.6 million at a share price of $366 under the cited volume limit.

Issuers also retain significant control. Before listing a tokenized stock created by an unaffiliated third party, a venue must provide 30 days’ notice to the company. The issuer can object and prevent its shares from being tokenized on that platform.

The SEC is separately offering conditional dealer-registration relief to certain liquidity providers, allowing them to supply assets to the pools without immediately operating under the full traditional dealer framework.

What This Means

The decision does not make tokenized equities broadly available overnight, but it gives Wall Street and crypto infrastructure providers a defined path to test blockchain-based settlement and liquidity. A successful experiment could eventually make shares easier to move between compatible financial platforms or use as collateral, though those functions are outside this exemption for now.

For Solana, the opportunity is primarily infrastructural rather than an immediate product launch. Its public-chain architecture and smart-contract ecosystem could become relevant if TSVs seek fast, auditable rails for regulated markets. The permissioned-access requirement and issuer veto, however, mean the market will likely develop through regulated applications built on public networks—not through unrestricted retail trading.
