Dinari said Tuesday it has become the first company to allow eligible U.S. investors to trade over 700 tokenized stocks using USDC through self-custody wallets.

Through a partnership with Circle, U.S. individuals and businesses can buy and sell every stock in the S&P 500 directly onchain, the firm said.

"For decades, investing and digital assets have existed in separate financial systems," Dinari co-founder and CEO Gabriel Otte said in a statement. "This launch brings them together, allowing investors to move seamlessly between stablecoins and U.S. equities while preserving the protections of traditional capital markets."

Dinari’s tokenized equities, called dShares, are each backed by a corresponding underlying security held in qualified custody, the firm said. The company warned that markets for tokenized securities may be limited, potentially making them harder to sell at a desired time or price.

Tokenizing equities has generated significant interest across crypto, from both blockchain-native firms to traditional-finance heavyweights such as JPMorgan and Goldman Sachs. But exactly how broadly they will trade and be regulated remains uncertain, despite growing support among U.S. policymakers.

Last month, the Depository Trust & Clearing Corp., the U.S. securities clearing and settlement giant, said it had successfully processed production trades using tokenized securities, including equities and U.S. Treasuries. More than 30 firms participated, including BlackRock, Circle, Goldman Sachs, JPMorgan and Nasdaq.

Dinari acknowledged Tuesday that “the legal and regulatory treatment of tokenized securities and digital assets continues to develop and may change, which could affect their availability, value, transferability, or the operation of the platform.”

A little more than a year ago, Dinari said it had secured an approval making it the first tokenized-equity platform to receive such authorization in the United States.
