Base Pushes Beryl Mainnet Launch to June 26 for B20 Registry Completion

Key Highlights

• Base postpones Beryl implementation by 24 hours to ensure B20 registry readiness
• B20 token standard introduces native support for stablecoins and real-world assets
• Registry initialization must complete before native B20 token deployment can proceed
• Withdrawal timeframe from Base to Ethereum reduced from seven days to five days
• Integration of Reth V2 promises up to 50% reduction in node storage requirements

The Ethereum layer 2 network Base has postponed its Beryl mainnet implementation by 24 hours to ensure proper B20 Activation Registry configuration. Beryl will now go live on June 26 at 18:00 UTC, providing additional time for the registry to initialize before the hard fork executes.

B20 Registry Initialization Necessitates Schedule Adjustment

Base initially targeted June 25 for Beryl’s launch, but development teams discovered a critical timing dependency. The B20 Activation Registry needs to complete its initialization sequence before developers can begin deploying native B20 tokens. This initialization process could take up to 60 minutes following activation.

The registry manages B20 feature flag availability throughout the network post-hard fork. To prevent activating Beryl before these critical functions were operational, the team rescheduled the mainnet deployment. While the timeline has shifted, the upgrade’s technical components remain unchanged.

Beryl brings B20 to Base—a protocol-native token standard designed specifically for stablecoins and tokenized real-world assets. B20 tokens function through Rust precompiles embedded directly within Base node software, unlike conventional ERC-20 contracts. Despite this fundamental difference, B20 maintains full ERC-20 compatibility and incorporates ERC-2612 permit functionality.

Enhanced Token Management and Accelerated Bridge Transfers

The B20 Issuer Toolkit provides comprehensive features including role-based permissions, minting and burning controls, transfer restrictions, and configurable supply limits. Additionally, it offers freeze and seizure capabilities for token issuers navigating regulatory compliance requirements. These functionalities embed core token governance directly into the protocol rather than relying on external smart contracts.

Beryl simultaneously decreases the standard withdrawal duration from Base to Ethereum from seven days down to five days. The majority of bridge providers utilize this single-proof withdrawal mechanism for cross-network transfers. Base attributed this improvement to Multiproofs enhancements delivered through the preceding Azul upgrade.

The upgrade further incorporates Reth V2 into Base’s node architecture. According to Base, this software implementation can cut node storage demands by as much as 50 percent. It additionally accommodates higher block gas limits, creating opportunities for expanded network throughput.

Recent Network Disruption Unrelated to Upgrade Postponement

Base encountered a block production halt lasting approximately two hours on June 25, prior to Beryl’s adjusted activation schedule. Engineering teams identified the cause as a consensus failure triggered by an invalid block entering the sequencing pipeline. Production subsequently resumed, and the team confirmed the incident bore no connection to the Beryl postponement.

The network emphasized that user assets remained secure throughout the disruption, despite the temporary cessation of block creation. Base founder Jesse Pollak stated that network interruptions are incompatible with infrastructure supporting worldwide financial operations. While the outage increased operational scrutiny, it didn’t affect Beryl’s planned functionality.

Beryl succeeds Azul, which deployed to mainnet in May as Base’s inaugural independent upgrade. The network has scheduled Cobalt, its subsequent major upgrade, for September. Cobalt is expected to deliver account abstraction capabilities, smart account support, gas sponsorship, transaction batching, and expanded B20 features.
