Base has deployed its Beryl upgrade to the Sepolia testnet and has scheduled the release for mainnet activation on June 25, introducing a native token standard and reducing withdrawal times to Ethereum. Base’s engineering team said in a blog post on Thursday that Beryl adds B20, a protocol-level token standard that allows issuers to create stablecoins and other assets directly within Base’s node software.

Base said B20 supports the full ERC-20 specification and includes ERC-2612 permit functionality, which allows token holders to authorize spending through signatures rather than separate approval transactions. The company said existing wallets, exchanges, and indexers that support ERC-20 tokens can integrate B20 assets without modification.Unlike traditional ERC-20 tokens that operate through smart contracts, B20 tokens run as precompiled contracts inside Base’s node software. Base said the token logic is written in Rust and executes directly within the protocol rather than through EVM bytecode. The release includes an Issuer Toolkit with role-based permissions, minting and burning controls, optional supply limits, transfer restrictions, and freeze and seizure capabilities intended for regulated issuers. Base said issuers can choose between a general-purpose asset model and a stablecoin-specific model that uses six-decimal precision and a customizable currency code.
