trace_call - Sonic RPC Method

Traces a call without creating a transaction on Sonic, returning the trace output.

When to Use This Method

• Trace simulated execution of multiple calls - Preview internal calls before committing a transaction on Sonic
• Pre-execution analysis - Test contract interactions without spending gas for ultra-fast DeFi, high-frequency trading dApps, and performance-critical 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
