This method requires an archive node. It is not available on full nodes.

Use Cases

  • Transaction debugging - Understand exactly what happened
  • Failure analysis - Find where and why a transaction reverted
  • Gas optimization - Analyze gas usage for high-volume DeFi (GMX, Uniswap, Aave), gaming, and cross-chain applications

Tracer Options

  • { tracer: "callTracer" } - Call tree tracer
  • { tracer: "prestateTracer" } - Pre-state tracer
