Base Cuts Withdrawal Times, Adds Native Token Standard on Beryl

Beryl extends work introduced through Azul, Base’s first independent network upgrade that reached mainnet in May. Azul introduced Multiproofs, a system that combines trusted execution environment proofs and zero-knowledge proofs to verify withdrawals and improve security.

Multiproofs created a fast withdrawal route capable of finalizing transactions in about one day when both proof systems agree, Base said. The option has seen limited adoption because generating zero-knowledge proofs remains expensive.

Beryl focuses on the withdrawal route most users rely on. The original seven-day delay came from Base’s earlier fault-proof framework, which reserved time for challenges against disputed withdrawals. Multiproofs narrowed the role of that delay to identifying and disabling faulty provers, which allowed the company to reduce the waiting period further.

The upgrade also includes Reth V2, the latest version of the Rust-based execution client that Base adopted after replacing legacy OP Stack clients through Azul. Base said the software update reduces storage requirements for full, minimal, and archive nodes and enables higher block gas targets without overwhelming sequencer or RPC infrastructure.

Beryl reached the Sepolia testnet about four weeks after Azul’s mainnet launch. Base attributed the faster release cycle to its February decision to move away from a shared dependency on Optimism’s OP Stack and operate on its own unified technology stack.

The company said its next planned upgrade, Cobalt, is targeted for September. That release is expected to introduce native account abstraction with protocol-level smart accounts, gas sponsorship, transaction batching, additional B20 functionality, and a unified node binary that combines consensus and execution clients.
