Base Mainnet Azul Upgrade May 28, 2026 18:00-19:00 UTC

On Thursday, May 28th at 18:00 UTC (Unix timestamp 1779991200), Base Mainnet will undergo the Azul upgrade.

This upgrade includes:
- Osaka support
- Simplified Flashblocks WebSocket format
- A new multi-proof system enabling faster withdrawals and a path toward stronger decentralization
- Support limited to Base Node (Reth) and Base Consensus clients only

Binary support will be restricted to just Base Node (Reth) and Base Consensus clients. Alchemy nodes will be migrated before activation.

We are not expecting any downtime.  Follow Base Network status updates at:
