Glamsterdam testnet upgrade delayed, EIP-8037 found to have contract compatibility issues

Odaily reports: Toni Wahrstätter posted that ChainSecurity's report indicates EIP-8037 has compatibility and security issues with certain smart contracts, and core developers decided last week to delay the Hoodi testnet upgrade to Glamsterdam. The issues discovered include that remaining Gas during transaction execution may increase, causing some Gas counting logic to underflow and trigger a revert, or triggering code paths that should not have been executed, making transactions appear successful; some contracts may also underestimate Gas usage because they cannot correctly calculate Gas consumption during calls. ChainSecurity previously stated it had found 13 real cases and is conducting responsible disclosure with the affected projects.

Toni Wahrstätter said that this week further investigation of the relevant contracts and evaluation of solutions will be conducted, and the work may require coordination among application developers, core developers, auditors, and node operators, and in the worst case may require adjusting the protocol specification. He reminded application developers and auditors to check contract compatibility with EIP-8037 and EIP-8038 and to report issues promptly.
