Ethereum Layer 2 network Base has pushed its Beryl mainnet upgrade to June 26 at 18:00 UTC, one day later than originally scheduled, to ensure the hard fork's underlying B20 Activation Registry is fully operational before it activates.
The delay centers on a timing dependency baked into Beryl's architecture, according to the team behind the Coinbase-incubated scaling network.
Developers cannot deploy tokens on Base's new native B20 standard until the Activation Registry — which controls whether B20's feature flags are live — comes fully online, a process that can take up to one hour after the hard fork itself activates.
Beryl was originally scheduled to go live on June 25. Separately, Base's mainnet suffered a roughly two-hour block production outage that day after a consensus failure caused an invalid block to enter the sequencing pipeline. The team said the incident was unrelated to the planned Beryl upgrade.
Beryl is Base's second independent network upgrade, following Azul, which activated on mainnet in May.
