trace_call - Tempo RPC Method
Simulate a call on Tempo with Parity-style trace_call. Choose trace, vmTrace or stateDiff output for a block, without sending a transaction.
Tempo RPC endpoint: endpoint URLs, plans and pricing.
Traces a call without creating a transaction on Tempo, returning the trace output.
Archive Node Required
This method requires an archive node. It is not available on full nodes.
When to Use This Method
- Trace simulated execution of multiple calls - Preview internal calls before committing a transaction on Tempo
- Pre-execution analysis - Test contract interactions without spending gas for merchant settlement, treasury operations, payout automation, and stablecoin-native financial applications
- Batch trace simulations - Execute several calls sequentially where each can depend on prior state changes
- Contract interaction analysis - Understand how multiple contracts interact through a simulated execution chain
Best Practices
- Similar to debug_traceCall but supports multiple calls in one request
- Each call has its own trace configuration for fine-grained control
- Use for batch simulation analysis of dependent call sequences
- Requires archive node access for historical block tracing
