Dinari, an issuer of tokenized U.S. equities, and tZERO Group, a blockchain-based financial infrastructure provider, said Wednesday they are partnering to build an operating framework that would let broker-dealers offer tokenized U.S. stocks.

The rollout spans four blockchains and 200 tokenized stocks.

The DeFi protocol received approval from the SEC to offer tokenized stock trading services to U.S. users.
