Odaily Planet Daily News 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. The exact release date will be provided when the team is confident that it is stable. zkSync Developers said that there were two issues affecting the testnet (these issues have now been resolved): First, due to instability issues in the eth_sender service (responsible for submitting transactions to the L1 zkSync smart contract), no L1 submission blocks were submitted for about 1 day. This was caused by a very different gas market for Blob pricing on Sepolia. Second, no proofs were submitted for more than two days, resulting in delayed withdrawals. This is caused by logical differences between the in-circuit VM (the ZK circuit used to generate proofs) and the out-of-circuit VM (the VM on the server side, which is executed immediately when a transaction is submitted).
