- Base introduced the B20 token standard for native asset issuance.
- Beryl reduces Ethereum withdrawal delays from seven days to five.
- Reth V2 expands blockspace capacity while lowering node storage.
Coinbase-incubated Ethereum Layer 2 network Base has introduced a new native token standard as part of its upcoming Beryl upgrade, which is scheduled for mainnet activation on June 25. The network deployed the upgrade to the Base Sepolia testnet on Thursday, giving developers and issuers an early look at features designed to improve asset issuance and network efficiency.
At the center of the update is B20, a native token standard that allows stablecoins and other digital assets to be issued directly within Base’s node software. Unlike traditional ERC-20 tokens, which operate through smart contracts, B20 functions as a precompiled contract embedded inside the network infrastructure.
Base said B20 remains fully compatible with the ERC-20 standard and supports ERC-2612 permits. As a result, wallets, exchanges, and indexing services built for ERC-20 assets can continue operating without major changes. Users can also approve transactions through signatures instead of submitting separate approval transactions.
The standard launches with an Issuer Toolkit that includes role-based permissions, minting and burning controls, optional supply caps, transfer restrictions, and compliance-focused asset management tools. Additionally, Base has introduced two B20 variants, including a general-purpose asset model and a stablecoin version with fixed six-decimal precision and issuer-defined currency codes.

Beryl Cuts Withdrawal Delays and Improves Scalability
Beryl also reduces the standard withdrawal period from Base to Ethereum. Previously, users had to wait seven days when using the most common withdrawal route. Under the new upgrade, that waiting period falls to five days.
The change builds on Multiproofs, a verification system introduced through the Azul upgrade earlier this year. While Multiproofs enabled a faster one-day withdrawal option, high zero-knowledge proof costs limited its adoption. Consequently, Base focused on improving the withdrawal path most users already rely on.
Beyond withdrawal improvements, Beryl introduces Reth V2, the latest version of Base’s Rust-based execution client. The update reduces storage requirements across node types and supports higher block gas targets. Consequently, developers gain access to more blockspace without placing additional pressure on network infrastructure.
Base’s next upgrade, Cobalt, is expected in September and will introduce native account abstraction, transaction batching, gas sponsorship features, and additional B20 functionality.
