debug_traceBlockByNumber

debug_traceBlockByNumber - Celo

debug_traceBlockByNumber. Returns detailed traces for all transactions in a block specified by its number

debug_traceBlockByNumber - celo [Value: 90CU]
The debug_traceBlockByNumber method traces the execution of all transactions within a specified block, identified by its block number
Use cases

Use cases

  • Analyze block's internal transactions for debugging purposes
  • Trace smart contract interactions within a specific block
  • Investigate gas usage for all transactions in block
Constraints

Constraints

  • Requires valid block number as input parameter
  • Node must support the debug_traceBlockByNumber method
  • High computational cost for tracing complex blocks
