For decades, buying stocks has meant going through brokers, waiting for trades to settle, and limited trading when stock markets are closed. Dinari is trying to change that. On Tuesday, the San Mateo, CA-based company that turns publicly traded shares into tokens announced that is putting the entire S&P 500 on the blockchain, and making those tokenized stocks available to U.S. investors

“One day, I’m predicting… the token itself will be the trusted ledger of the stock. The beauty of that is, then we truly own it,” Dinari cofounder and CEO Gabriel Otte told Fortune.

Dinari’s model replaces the traditional brokerage stack with a wallet-based system where users can fund accounts instantly with the stablecoin USDC. Dinari says the arrangement, which entails a partnership with stablecoin giant Circle, allows U.S. investors to buy and sell stocks via self-custody wallets for the first time.

The startup added that it is seeking to be a bridge between the $300 billion stablecoin market and the more than $60 trillion U.S. equities market.

Circle declined to comment, citing a quiet period ahead of its upcoming earnings report.
