At 7:29 UTC today, on epoch 222464, the Pectra network upgrade went live on the Sepolia testnet.

Unfortunately, an issue with Sepolia's permissioned deposit contract prevented many execution layer clients from including transactions in blocks. The root cause was identified within minutes, and client teams immediately began working on a fix.

This issue is due to Sepolia's configuration and could not occur on the Ethereum mainnet.

Around 14:00 UTC today, validators deployed a fix that restored the network to normal throughput.

All Sepolia node operators must now upgrade their execution layer clients to the versions listed below to maintain network compatibility.

This post will be updated with any further developments regarding the Sepolia Pectra deployment.

A postmortem will be available in the Pectra project management folder once the incident is resolved.
