Ethereum Foundation researcher Toni Wahrst?tter announced in a post that core developers last week decided to delay the Hoodi testnet upgrade to Glamsterdam, following a ChainSecurity report uncovering compatibility and security issues between EIP-8037 and certain smart contracts. Identified problems include: residual gas may rise during transaction execution, causing underflow in some gas counting logic and triggering rollbacks, or activating code paths that should not execute, making transactions appear successful. Additionally, some contracts may incorrectly calculate gas consumption during calls, leading to underestimated usage. ChainSecurity previously noted it has found 13 real-world cases and is conducting responsible disclosure with affected projects. Wahrst?tter said further reviews of related contracts will be carried out this week to assess follow-up solutions, which may require collaboration among application developers, core developers, auditors, and node operators. In the worst scenario, protocol specifications may need adjustment. He urged application developers and auditors to verify their contracts’ compatibility with EIP-8037 and EIP-8038, and report issues promptly.
