max_used_gas to SimCallResult#3707Conversation
Add optional `maxUsedGas` field to `SimCallResult`, mirroring ethereum/execution-apis#746 and ethereum/go-ethereum#32789. This field represents the maximum gas consumed during execution before refunds are applied, enabling more accurate gas limit estimation for complex transaction sequences.

Wire up the new `max_used_gas` field from alloy SimCallResult: - For Success: gas_used + gas_refunded (peak gas before refunds) - For Halt/Revert: same as gas_used (no refunds apply) Uses patched alloy branch: alloy-rs/alloy#3707 Amp-Thread-ID: https://ampcode.com/threads/T-019c6b14-bfd0-71df-bce9-533057940778 Co-authored-by: Amp <[email protected]>

Summary
Adds optional
maxUsedGasfield toSimCallResultforeth_simulateV1responses.Motivation
Mirrors ethereum/execution-apis#746 and ethereum/go-ethereum#32789.
The
maxUsedGasfield represents the maximum gas consumed during transaction execution before refunds are applied. This is valuable for DeFi applications that need accurate gas limit estimation for complex transaction sequences (e.g. approve + swap flows), wheregasUsed(post-refund) can underestimate the required gas limit.Changes
