The Securities and Exchange Commission announced it will allow qualifying platforms to test trading real U.S. stocks on public blockchains for up to five years without registering as national securities exchanges.
The exemption applies only to tokenized securities that preserve traditional shareholder rights such as voting and dividend entitlements. Products that merely track price movements without ownership rights remain excluded.
Platforms approved under the sandbox, called Tokenized Securities Venues, may use smart contracts and liquidity pools to match trades. They must operate on public, permissionless blockchains with auditable software, while access to the trading venue stays permissioned. Certain liquidity providers receive conditional relief from dealer registration rules.
Participating venues face strict limits: they can tokenize no more than 75 of the most liquid stocks and handle no more than 0.25% of average daily trading volume for those securities. A second tier permits up to 250 stocks with a 2.5% volume cap. The SEC designed these caps to ensure a modest, controlled start.
Companies whose shares are tokenized retain veto power. The issuer must receive 30 days’ notice before a third party proposes tokenization, and can block the offering with a simple objection.
The framework does not permit leverage or lending against tokenized stocks. Settlement, transferability and collateral use remain subject to future rulemaking, though the SEC expects blockchain infrastructure to eventually enable faster settlement and programmable market features.
Synthetic products that mimic stock performance without actual ownership rights fall outside the exemption. The SEC emphasized that tokenized shares must convey the same rights as traditional stock, preserving protections such as voting and dividend claims.
The move follows a broader push for regulatory clarity in digital asset markets. It comes after Congress rejected the Clarity Act, prompting the SEC to act within existing authority. The agency described the sandbox as an experiment to gather evidence that could shape future rulemaking or legislation.
By separating the technology from the regulatory framework, the SEC aims to let traditional finance explore blockchain tools while maintaining investor protections. The experiment may reshape how stocks trade, but it does not alter the legal status of securities or open public blockchains like those used in decentralized finance to unrestricted trading.
The agency’s approach reflects a cautious expansion of innovation in regulated markets, offering a narrow path for testing blockchain’s role in securities trading while keeping oversight firmly in place.
