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

CoinFeed reported on June 17th that Coinbase's Layer 2 network, Base, is about to launch a hard fork upgrade to Beryl. This upgrade introduces the B20 native token standard, shortens the final confirmation period for single-proof withdrawals from 7 days to 5 days, and upgrades 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 19th and on the mainnet at 2:00 AM (UTC+8) on June 26th. B20 is Base's native token standard, a pre-compiled Rust-based ERC-20 compliant token designed for stablecoin, RWA, and long-tail token issuers. It includes a built-in compliance toolkit, including transfer policies, freezes and seizures, role-based access control, memos, and supply caps.
