trace_callMany

Performs multiple call-traces on top of the same block. You can analyze the interactions between different transactions and contracts.

Parameters​

  • trace call parameters: [Required] Array of trace call parameters. Each trace call parameter itself is an array containing the following:
    • transaction call object: [Required] Transaction call object containing the same data as in the trace_call parameter.
    • options:[Optional] An array of tracing options. Tracing options are trace and stateDiff. Specify both options or none.
  • block parameter: [Required] The hexadecimal block number, or the string latest, earliest, or pending. See the default block parameter. The block parameter is applied uniformly to all trace calls in the trace call parameters array.

Returns​

Example​

Replace <YOUR-API-KEY> with an API key from your MetaMask Developer dashboard.
