Trace a transaction execution on Scroll. Requires archive node for debugging zero-migration DeFi protocols, zkEVM-native dApps, and 100+ ecosystem projects with native Ethereum tooling.

Traces a transaction execution on Scroll 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 zero-migration DeFi protocols, zkEVM-native dApps, and 100+ ecosystem projects with native Ethereum tooling

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 Scroll. Simulate transactions, debug contract interactions, and analyze gas usage with full execution traces.

eth_chainId

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