Ethereum Foundation: Noted that some L2 deployments on Sepolia are not functioning properly and require a software update

ChainCatcher message, the Ethereum Foundation officially released a reminder update stating that it has noticed some L2 deployments on Sepolia not functioning properly over the past few days, due to EIP-7549 changing the proof format.

To address the Fusaka upgrade, all Blob initiators are urged to update their software to create Cell Proofs instead of Blob Proofs. The Ethereum Foundation also added that L2s and other entities heavily reliant on the Ethereum roadmap are encouraged to follow the ACD process and engage more directly with the community. Teams are also encouraged to deploy contracts and test infrastructure on the development network before migrating to the first testnet.

Another good way to stay updated is by using the Ethereum package provided by Kurtosis, which can be used to create a local network that complies with the latest specifications.
