Base has pushed its Beryl mainnet upgrade to June 26 at 18:00 UTC, citing timing concerns around its B20 Activation Registry. Developers will not be able to deploy tokens on Base's new native B20 standard until that registry comes online, a process that can take up to one hour after the hard fork activates.
Why it matters
The slip is procedural rather than technical, but it matters because B20 is the native token standard Base built to anchor its on-chain asset layer. The Activation Registry is the gatekeeper that lists which contracts are recognised as compliant, so any token issuance flow that depends on B20 effectively waits one extra hour on top of the new date.
Market impact
For builders targeting the June window, the practical ship date is now June 26 plus the registry warm-up. The delay is unlikely to move ETH or broader L2 sentiment on its own, but it does reset the calendar for the first cohort of B20-native launches and any ecosystem incentives tied to the upgrade.
