Celestia Mocha - Mocha-4 --> Mocha-5 Network Switch-over

Scheduled for Aug 31, 09:00 - 17:00 UTC

Scheduled

Quicknode is switching the Celestia Mocha Testnet from mocha-4 to mocha-5, in line with the Celestia team's network restart.

During the maintenance window, your Mocha endpoint may return errors or stale data while nodes switch over to mocha-5. You will see the latest block height drop, since mocha-5 restarts at block height 1.

*Celestia mainnet is not affected.*

After the switch:
- Endpoints serve mocha-5 (chain ID mocha-5). Update your chain ID to mocha-5 if it is hardcoded in your apps.
- Historical mocha-4 data is not available on mocha-5.
- Celestia shuts down mocha-4 on Sept 1, 2026 — move any remaining mocha-4 workflows before then.
