Base Beryl Upgrade Launches on Testnet Ahead of June 25 Mainnet
Base, Coinbase-backed Ethereum Layer 2, has activated the “Beryl” upgrade on the Sepolia testnet, ahead of its June 25 mainnet rollout. Traders should note three core changes: (1) the new B20 token standard for easier on-chain token creation and execution within the network (ERC-20 compatible), (2) faster Ethereum withdrawals via shorter withdrawal delays from 7 days to 5 days, and (3) Reth V2, an execution-client update that reduces node storage, improves processing and state computation performance, and supports greater blockspace capacity.
Beryl is built on the prior “Azul” upgrade and aims to strengthen Base’s scalability and developer throughput. The shorter withdrawal timeline is linked to newer multiproof verification, designed to maintain security while reducing settlement time for the most common withdrawal path. More advanced proof routes may settle even faster.
No user action is required, but node operators must upgrade software before activation. Overall, this is a pre-mainnet “infrastructure readiness” event that could improve liquidity efficiency (faster exits/bridging capital utilization) and reduce operational costs for the network—factors that often support positive sentiment for L2 activity leading into a mainnet upgrade.
Bullish
This upgrade is a constructive pre-mainnet catalyst for Base’s ecosystem. Faster withdrawals (7→5 days) can improve capital efficiency for traders and bridging providers, while Reth V2 should reduce node resource costs and increase throughput, which often supports increased on-chain activity. Historically, L2 performance and withdrawal-flow improvements tend to attract liquidity ahead of mainnet activations, creating short-term positive sentiment. In the long run, better scalability and easier token deployment (B20, ERC-20 compatibility) can expand DeFi/RWA and wallet integrations, potentially sustaining activity growth. However, since there’s no mention of a token launch or immediate token-specific impact, the bullish bias is mainly tied to ecosystem usage and expectations rather than guaranteed price action.
