Base, Coinbase's Ethereum layer-2 network, will activate its new B20 token standard on July 8. The standard is designed for issuing stablecoins, tokenized real-world assets (RWAs), equities, and other fungible tokens.
According to Base documentation, B20 allows developers to issue tokens without creating and auditing custom ERC-20 smart contracts. The project said the approach is intended to significantly simplify and accelerate token issuance.
B20 introduces two token types: Asset and Stablecoin. The Asset format supports a configurable number of decimal places, while Stablecoin uses a fixed six-decimal format and requires issuers to specify an underlying fiat currency, such as the U.S. dollar or euro.
Issuers will be able to set supply caps, control token minting and burning, pause transfers, define transfer rules, and attach notes to transactions.
The B20 standard was introduced as part of the Beryl upgrade, activated in late June 2026. In addition to preparing the network for the new token format, the upgrade reduced withdrawal times from seven days to five days and introduced several performance improvements.
On June 25, the network stopped producing new blocks for nearly two hours because of a consensus error. A day later, another outage lasted about 20 minutes after a sequencer malfunction following a system restart.
The Beryl upgrade itself was also delayed by one day because of a technical issue involving the B20 activation registry.
Earlier this year, Base completed its migration from the OP Stack infrastructure to its own native architecture. According to the development team, replacing third-party components with an in-house codebase improved development coordination and reduced operational costs.
Earlier, Coinbase unveiled a major upgrade to the Base ecosystem by launching Base App, built on the former Coinbase Wallet. The new application combines a crypto wallet, payments, trading, social features, and access to decentralized applications within a single interface.
