Dinari opened tokenized U.S. stock trading to U.S. investors on Tuesday, saying 724 tokenized U.S. stocks and ETFs — including every company in the S&P 500 — can now be bought with USDC from self-custody wallets by eligible investors in the United States.

The company said it is the first platform to make the 724 tokenized stocks available to both eligible U.S. investors and U.S. businesses, with purchases settled in USDC through a partnership with Circle and broker-dealers able to license Dinari's API-based infrastructure to offer the products to their own customers.

Avalanche said the tokens are live on its C-Chain through the Dinari Trading App. Dinari said it currently supports Ethereum, Avalanche, Arbitrum and Base, and will expand to Sei and Solana. Alongside its own app, the company named Monaco, Eldora, Kredete, Yield.xyz, Liminal, Para, Privy and Axal as launch partners.

The tokens, branded dShares, are backed by corresponding underlying securities held in qualified custody, according to Dinari. The company said they are designed to preserve the rights and protections of traditional stock ownership, including execution at the national best bid and offer, voting rights, cash dividends, corporate actions and ownership of the backing security.
