debug_traceTransaction - IoTeX RPC Method

Trace a transaction execution on IoTeX. Requires archive node for debugging decentralized physical infrastructure (DePIN), IoT device identity (ioID), and AI-verified real-world data.

Traces a transaction execution on IoTeX by transaction hash.

Archive Node Required

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 decentralized physical infrastructure (DePIN), IoT device identity (ioID), and AI-verified real-world data

Tracer Options

  • {} - Default opcode tracer (verbose)
  • { tracer: "callTracer" } - Call tree tracer
  • { tracer: "prestateTracer" } - Pre-state tracer

Code Examples

debug_traceCall

Trace a call without creating a transaction on IoTeX. Simulate transactions, debug contract interactions, and analyze gas usage with full execution traces.

eth_chainId

Get the chain ID for IoTeX. Essential for transaction signing and network verification.
