debug_traceTransaction - Mantle RPC Method

Traces a transaction execution on Mantle by transaction hash.

When to Use This MethodCopy Anchor Link

• Analyze transaction execution step-by-step - Trace every opcode and internal call in a completed transaction for liquid staking (mETH $1.87B TVL), institutional DeFi via Bybit, and yield optimization strategies
• Debug failed transactions - Pinpoint the exact opcode and call depth where a transaction reverted on Mantle
• Examine internal call traces - Follow the full call tree including delegate calls and contract creations
• Gas usage profiling - Measure gas consumption per opcode to identify optimization opportunities

Best PracticesCopy Anchor Link

• Requires archive node access; not available on standard full nodes
• Traces can be very large for complex transactions with many internal calls
• Use tracer options like onlyTopCall or callTracer to limit output size
• Store traces off-chain for analysis rather than querying repeatedly
