Base to activate Beryl upgrade on June 25, 2026, rolling out B20 native token standard

Base, the Coinbase-backed Ethereum layer-two network, plans to activate its Beryl upgrade on mainnet on June 25, 2026, at 18:00 UTC. The release introduces B20, a native token standard built into node software rather than deployed as a smart contract. Base engineers say B20 is designed as a superset of ERC-20 so tokens remain compatible with existing wallets, exchanges and decentralized applications.
