Using debug_traceTransaction to Explain Failed EVM Bot Trades

Receipts show an outcome; traces reveal which nested call, proxy, or token behavior caused it.

Model the failure correctly

Preserve chain ID, hash, block hash, calldata, gas fields, quote, sender, and nonce before analysis.

Collect evidence

Start with call frames, resolve proxy implementations, and decode the deepest failing selector.

Build the control path

Normalize Geth, Erigon, Nethermind, and managed-provider results into one internal call-tree schema.

Handle edge cases

Run expensive tracing asynchronously with deduplication, deadlines, and concurrency limits.

Recovery procedure

Classify failures into stale quote, allowance, token semantics, router bug, gas, access control, or provider inconsistency.

Production metrics

Feed trace classifications back into simulation tests, alert routing, and regression fixtures.
