Trace JSON RPC

tenderly_traceTransaction

Replays transaction on the blockchain and provides information about the execution, such as status, logs, internal transactions, etc.

Params

1. Transaction hash STRING 32 byte hex value

Example

{
  "id": 0,
  "jsonrpc": "2.0",
  "method": "tenderly_traceTransaction",
