Coinbase tokenized stocks based on Base network go live with 1:1 share backing via B20

Base announced that Coinbase-issued tokenized stocks are live on the Base network under the B20 standard, with tokens representing real shares held 1:1 by regulated custodians and intended for eligible users to hold in self-custody wallets and use across Base’s DeFi ecosystem ^[1].

Coinbase’s tokenized stocks on Base were reported as starting with tokenized Apple, Nvidia, Meta, and Alphabet shares, issued under Coinbase’s new Abu Dhabi framework ^[2].

Reporting also described the Coinbase tokenized stocks on Base as offering 1:1 share backing, 24/7 trading, self-custody, and integration across DeFi ^[3].

Multiple outlets reported that Coinbase selected Chainlink for its tokenized US stocks on Base, including for continuous pricing and for use as an oracle that links Coinbase equities with broader Base DeFi markets ^{[4] [5]}.

CoinDesk and Crypto Briefing also characterized the integration as part of a broader effort to bring equities onto blockchain platforms, with one analysis suggesting the Base launch could accelerate DeFi growth and affect prospects for a future Base token release ^{[2] [6]}.
