Ethereum Discovers Smart Contract Compatibility Risk, Suspends Hoodi Testnet Hard Fork Ethereum developer Marius van der Wijden stated that security auditing firm ChainSecurity discovered that some projects rely on gas billing invariants that have become invalid due to the failure of EIP-8037 and EIP-8038 proposals in the Glamsterdam upgrade, causing smart contract compatibility issues. Ethereum core developers have decided to suspend the Hoodi testnet hard fork until the issue is resolved. The development team is collaborating with multiple auditing firms to conduct security checks and is urging smart contract developers to investigate the affected areas to assess whether adjustments to upgrade specifications are necessary.
