Base will activate its Beryl upgrade on June 25, introducing native B20 tokens, faster Ethereum withdrawals, and Reth V2 performance enhancements. The upgrade is the latest step for the Ethereum layer-2 network as it looks to improve throughput and reduce friction for users moving assets back to the main chain.
What Beryl includes
The core of the Beryl upgrade is the introduction of native B20 tokens on Base. These tokens are designed to operate directly within the layer-2 ecosystem, potentially simplifying transactions and reducing reliance on bridged assets. Beyond that, the upgrade targets two pain points for L2 users: slow withdrawals and network performance.
Faster Ethereum withdrawals
Withdrawals from Base to Ethereum have historically taken days. Beryl shortens that timeline significantly, though the exact new window hasn't been detailed. The change is expected to make the network more practical for users who need to move funds quickly, especially during volatile market conditions.
Reth V2 performance improvements
The upgrade also includes Reth V2, an update to the Rust-based Ethereum execution client that powers Base. Reth V2 brings optimizations that should lower latency and increase transaction throughput. For developers and regular users, that likely means cheaper and faster interactions on the network.
Upgrade timeline
Activation is scheduled for June 25. No further delays have been announced, and the network is expected to undergo a brief maintenance window around that time. Users holding assets on Base should check for any required actions before the upgrade goes live — though the team has indicated the transition will be seamless for most.
