Executes a list of bundles (a bundle is a collection of transactions), without creating transactions on the blockchain. Returns their traces. This method is akin to eth_callMany but provides detailed execution traces for each call, making it invaluable for debugging complex interactions involving multiple transactions.

​
Request

To use debug_traceCallMany, send a POST request with a JSON RPC call in the body.

​
Parameters

  • transactions (array): An array of transaction objects to be executed. Each transaction object includes:
    • from (string): The address the transaction is sent from (optional).
    • to (string): The address the transaction is directed to.
    • gas (string): The gas limit for the transaction.
    • gasPrice (string): The gas price for the transaction.
    • data (string): The data sent along with the transaction.
  • blockOverride (object): Optional overrides for the execution context block header, including:
    • blockNumber (string): Block number for the execution context.
  • Simulation Context (object): The context for the simulation, including block number and transaction index.
  • State Overrides (object): Optional state overrides for the execution context.

​
Response

The response includes detailed execution traces for each call in the bundles, providing insights into each step of the transactions’ execution.

  • result (array): An array of execution traces for each call, including:
    • structLogs (array): An array of execution steps (opcodes) taken by the call.
    • gas (integer): The gas provided by the call.
    • returnValue (string): The return value of the call, if any.
    • gasUsed (integer): The total gas used by the call.
    • failed (boolean): Indicates whether the call failed.

​
Use case

The debug_traceCallMany method is essential for:

  • Developers debugging complex interactions involving multiple transactions.
  • Analysts conducting forensic analysis of transaction sequences.
  • Tools and services that provide insights into Ethereum Virtual Machine (EVM) execution across multiple calls.
