Base’s B20 Activation Registry is scheduled to go live on mainnet on July 8 at 18:00 UTC, opening the network’s new native token standard to issuers after a delayed rollout window.
The registry is the switch that lets developers deploy B20 tokens on Base. Attempts to deploy before activation can revert with FeatureNotActivated, making the registry status the main checkpoint before teams launch tokens on mainnet.
B20 is an ERC-20 superset that keeps standard transfer, approval, balance and allowance behavior while adding built-in roles, supply caps, pausing, policy gating, memos and permit support. The format gives Base a token system that still works across wallets, exchanges, indexers and onchain applications, but runs through native precompiles instead of conventional smart contracts.
The new standard is part of Base’s Beryl upgrade, which pushed the Coinbase-incubated Ethereum Layer 2 further toward asset issuance, payments and tokenized financial products. Beryl introduced B20 as a native token standard, reduced the standard withdrawal delay and added Reth V2 support for scaling work.
B20 is designed for stablecoin issuers, real-world asset issuers, equity-backed products and long-tail token creators. The native token standard has two variants, Asset and Stablecoin, with the Stablecoin variant using fixed six-decimal formatting and a self-declared fiat currency code.
The structure gives issuers more than basic token transfers. B20 includes role-based access, transfer policies, freeze-and-seize functions, supply caps and metadata controls. Those features can already be built into ERC-20 contracts, but B20 moves more of that logic into Base’s native execution layer.
The activation lands as Base is trying to turn low-cost settlement into a broader issuance stack. Coinbase and Spiko opened stablecoin access to tokenized UCITS money-market funds through Coinbase Payments on Base, giving USDC and EURC holders a route into regulated money-market products without relying only on bank transfers.
Base has also become a more active trading and payments rail. The network flipped Solana in 24-hour DEX volumeduring a May liquidity rotation, while Coinbase’s x402 stack put Base inside a wider agentic payments push after 160 million processed x402 payments.
B20’s mainnet registry does not create a Base token or change ERC-20 itself. It gives issuers a Base-native deployment path for assets that need ERC-20 compatibility, lower execution costs, higher throughput and built-in controls, with the July 8 activation marking the point when mainnet deployment can begin once the registry is fully enabled.
