Christine Kim, a former Galaxy Digital analyst and current host of Ready for Merge, reported via X that Ethereum developers have tentatively agreed to apply the next upgrade, Glamsterdam, to the first public testnet, Sepolia, on October 6th at 22:53 (KST). However, as Devnet-9, the recent testnet for developers, has not been able to finalize blocks normally, Devnet-10 will be launched after bug fixes. If significant issues are found in Devnet-10, the Sepolia schedule may be postponed. The application schedules for Hoodi and the mainnet have not yet been determined.
