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.
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.
