Overview
- Base deployed Beryl to the Sepolia testnet and scheduled mainnet activation for June 25, so node operators must update software before the upgrade goes live.
- Beryl introduces B20, a protocol-level token standard that runs as precompiled contracts inside Base node software and supports ERC‑20 semantics including ERC‑2612 permit signatures.
- The upgrade reduces the common withdrawal delay from Base to Ethereum from seven days to five days by changing the route most bridges use while Azul’s earlier Multiproofs still enable an occasional one-day path.
- Beryl ships Reth V2, a Rust-based execution client that lowers disk use for full and archive nodes and allows Base to raise block gas targets without overloading sequencers or RPC services.
- The release adds an Issuer Toolkit with role-based minting, burning, supply caps, transfer controls and freeze options aimed at regulated issuers, and markets have priced roughly a 28.5% chance of a Base native token by year-end while stressing the upgrade itself is infrastructure rather than a confirmed token launch.
