According to PANews, zkSync Developers posted on the X platform that the zkSync Era Sepolia testnet is expected to be fully restored in the next few hours. The v24 mainnet upgrade will be postponed until later next week to give the team more time to evaluate the stability of the testnet. Once the team is convinced that it is stable, a firm release date will be provided.
According to zkSync Developers, there were two issues that affected the testnet (these issues have now been resolved). First, due to instability issues with the eth_sender service, no L1 commit blocks were submitted for about a day. Second, no proofs were submitted for more than two days, causing withdrawal delays.
In addition, zkSync Developers posted on the X platform that the team is investigating an ongoing issue with the zkSync Sepolia testnet. While the investigation continues, withdrawing Sepolia funds from the zkSync Era Sepolia testnet is unavailable. This investigation may affect the mainnet v24 version scheduled for release next Monday.
