The company announced on Tuesday that investors can buy and sell 724 tokenized US stocks, including all companies in the S&P 500 index, using Circle's USDC stablecoin via self-custody wallets. The product operates through Dinari's regulated broker-dealer and transfer agent infrastructure, with plans to soon support the Solana and Sei networks. This move marks the expansion of the custodial tokenization model into the US market, coming amidst increasing competition in blockchain-based stock trading.
