B20 runs as code built into Base's node software rather than as a separate smart contract, which Base expects to eventually make transfers about 50% cheaper while keeping full ERC-20 compatibility. Beryl also cuts the standard Base-to-Ethereum withdrawal wait from seven days to five and ships a built-in compliance toolkit, including the ability to freeze and burn tokens held by blocked addresses. Base, the Ethereum Layer-2 network built by Coinbase, will activate its Beryl mainnet upgrade on June 25, the company said , introducing a native token standard called B20. The upgrade has been live on Base's test network since June 18. B20 is the part that matters most for builders. Instead of deploying each token as a separate smart contract, B20 tokens run as code embedded directly in Base's node software, which Base says makes transfers cheaper and faster while keeping full compatibility with existing wallets, exchanges, and apps, per CryptoBriefing . The network expects native execution to eventually cut transfer costs by about 50% and double throughput. The standard is aimed at issuers of stablecoins, real-world assets, and long-tail tokens, and it ships with a compliance toolkit that would normally take months to build, as Base documentation describes .
