Ethereum’s research and testing teams have published findings from replaying historical transactions under Glamsterdam’s proposed gas schedule. The changes concern how the protocol accounts for the work of creating and accessing state.
The teams say most contracts are unaffected, while a small set depends on assumptions that the new schedule changes. Some flagged cases can be addressed by changing gas limits; other cases require closer examination.
The announcement links an impact checker and directs developers to test fixes on Platåberget. These findings concern software behaviour under a proposed network change. They are not a completed mainnet rollout, and the source should be checked for later revisions before technical changes are made.
