Briefings

A draft Ethereum Standard (ERC) proposes a standardized format for simulation results to ensure any independent party can verify outputs without relying on a trusted frontend. The standard defines a SimulationResult struct with fields for success status, gas usage, logs, state diffs, and snapshot IDs, requiring a hardware offline verifier to re-execute transactions and reject mismatches. This addresses the risk of compromised UIs by enabling machine-checkable artifacts for signatures and Scoped Capability Tokens.

Key points

• The draft ERC defines a SimulationResult struct containing success (bool), gasUsed (uint256), returnData (bytes), stateDiffHash (bytes32), logsHash (bytes32), snapshotId (block number + state root), and a canonical hash derived via keccak256 or EIP-712.
• Compliance requires that any compliant simulator produces identical canonical output for the same inputs, enabling recompute on components the UI does not control and binding results into signatures.

Context

This finding addresses the critical vulnerability where simulation results served by a compromised frontend are worthless. By standardizing the format, hashing, and verification of simulation results, the draft turns simulation from a trusted frontend service into a reproducible, machine-checkable artifact that can be bound into signatures and Scoped Capability Tokens, ensuring natural continuity with capability tokens and authority lifecycle.

Limitations

The evidence is a draft standard with no published implementation or test results. The specification details exact stateDiff encoding requirements and prestate proof binding mechanisms but does not specify implementation details or performance benchmarks. The draft status and lack of community feedback mean the standard's adoption timeline and practical utility remain uncertain.
