Sepolia Pectra Incident Update

The Ethereum Foundation deployed the Pectra upgrade on the Sepolia testnet at epoch 222464. Shortly after launch, a malfunction in Sepolia’s permissioned deposit contract disrupted the ability of execution layer clients to process transactions. The issue, specific to Sepolia’s configuration, was resolved rapidly through collaboration between the Foundation and client teams—restoring network functionality within hours.

Key Ideas

Testnet-Specific Disruption: A misconfiguration in Sepolia’s deposit contract interfered with transaction inclusion, temporarily halting throughput.
Swift Recovery Response: Ethereum’s developer community identified and resolved the root issue quickly, reinforcing the robustness of client coordination and upgrade protocols.
