Ethereum’s proposed safety checks could still let a bad trade through
Ethereum Foundation research examines draft EIP-7906, which would let Ethereum transactions include post-execution assertions that inspect state changes and revert actions when configured rules fail. Potential uses include enforcing swap outcomes, preserving account controls and constraining delegated agents or solver settlements. The proposal builds on frame transactions under EIP-8141 and remains under consideration for the Hegotá upgrade. Its safeguards are only as meaningful as the limits and reference values chosen: a transaction builder could set a permissive threshold or use a manipulable price source. Assertions also cannot roll back validation-prefix changes or gas costs, and must be required by account or protocol logic to prevent bypasses.
