Base will activate the Beryl hard fork upgrade, introducing the B20 native token standard

According to official sources, Base is about to launch the Beryl hard fork upgrade, introducing the B20 native token standard. This will shorten the single-proof withdrawal finality period from 7 days to 5 days, and upgrade to Reth V2, reducing disk usage by 50% and increasing 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 via Rust precompiles. It is specifically designed for issuers of stablecoins, RWAs, and long-tail tokens, and comes with a built-in compliance toolkit including transfer strategies, freezing and clawback, role-based access control, memos, and supply caps.
