B20: Native Token Standard
B20 is Base’s native token standard - ERC-20 compatible tokens implemented as Rust precompiles, designed for stablecoin, real-world asset, and long-tail token issuers.
Native Account Abstraction (EIP-8130)
A later Beryl phase brings account abstraction into the protocol. Accounts configure authorized actors and signature validation onchain. Apps get portable smart accounts, scoped session keys, atomic batching, and native gas sponsorship without bundler or relay infrastructure. EIP-8130 is experimental and currently runs only on the vibenet devnet.
Withdrawals
The single-proof dispute game finalization window is reduced from 7 days to 5 days. The dual-proof fast path (TEE + ZK) introduced in Azul remains at 1 day.
Shortening the single-proof window frees capital for fast-bridge liquidity providers sooner, reducing fees and improving reliability for users who bridge through third-party partners.
