Coinbase's Layer 2 network, Base, will activate the Beryl hard fork upgrade on its mainnet on June 26, introducing the B20 native token standard. This upgrade will also shorten the final confirmation period for single-proof withdrawals from 7 days to 5 days and upgrade to Reth V2, which reduces disk usage by 50% and increases throughput by 33%. The Beryl upgrade will first be activated on the Sepolia testnet on June 19. The B20 token standard, compliant with ERC-20, is pre-compiled in Rust and designed for stablecoin, RWA, and long-tail token issuers. It features a compliance toolkit with transfer strategies, freezes and seizures, role-based access control, memos, and supply caps. The Azul dual-proof fast track (TEE+ZK) for withdrawals will remain at a 1-day adjudication window.
