Base, Coinbase’s Ethereum layer 2 network, just cleared two significant milestones in quick succession. The Beryl network upgrade activated on mainnet on June 25, and the B20 Native Token Standard followed independently on July 8, together marking what the team describes as a foundational shift in how tokens get issued on the network.
What Beryl actually changed
The Beryl upgrade went live on June 25 at 18:00 UTC, and it brought one immediately noticeable improvement: withdrawal delays dropped from 7 days to 5 hours.
Beryl also shipped performance improvements to Reth V2, the execution client Base runs. Reth V2 is a Rust-based Ethereum client known for its throughput efficiency, and the Beryl enhancements push that performance further.
The upgrade sits in a sequence. Base ran the Azul upgrade in May 2026, Beryl followed in June, and a Cobalt upgrade is already on the roadmap.
