Tracing and debugging on the Monad blockchain can be done by using the following methods:
debug_traceTransaction
debug_traceBlockByNumber
debug_traceBlockByHash
debug_traceCall
These methods support multiple tracers including:
callTracer — traces all calls made during execution
prestateTracer — returns the state accessed during execution
stateDiffTracer — returns state changes made during execution
This information can be used for:
Debugging — understand why transactions failed or behaved unexpectedly.
Security analysis — analyze contract interactions and fund flows.
Gas optimization — identify expensive operations in contract execution.
Forensics — trace transaction paths for audit and compliance.
