Base will activate the Beryl hard fork upgrade on the mainnet on June 26, introducing the B20 native token standard.

Odaily reported that, according to official sources, Base is about to launch the Beryl hard fork upgrade, introducing the B20 native token standard, shortening the withdrawal final confirmation period for single proofs from 7 days to 5 days, and upgrading Reth V2, which will reduce disk usage by 50% and increase throughput by 33%.

Beryl will be activated on the Sepolia testnet at 2:00 AM UTC+8 on June 19 and on the mainnet at 2:00 AM UTC+8 on June 26.

B20 is Base's native token standard—an ERC-20 compatible token implemented in Rust for stablecoins, RWA, and long-tail token issuers. It has a built-in compliance toolkit that includes transfer policies, freezing and seizure functions, role-based access control, memos, and supply caps.
