debug_traceTransaction

BNB Smart Chain / https://triport.io/rpc/bsc

Minimum tier: Pro

BNB Smart Chain method guide

Last updated:

debug_traceTransaction replays one BNB Smart Chain transaction in the selected debug tracer and returns a trace frame describing its execution.

Use it to inspect internal calls, input and output data, or gas consumption for a known transaction hash when a receipt only reports the final outcome. The optional tracer object selects the tracer, timeout, and tracer-specific configuration.

Unlike debug_traceBlockByNumber, this method targets one transaction rather than a whole block. It is best-effort because the pool currently has a single public source with a shared quota and no SLA.

Parameters

debug_traceTransaction parameters
NameTypeRequiredDescription
transactionHashHashYes
optionsTraceOptionsNo

Returns

debug_traceTransaction return value

traceTraceFrame

Examples

curl https://triport.io/rpc/bsc \
  -X POST -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"jsonrpc":"2.0","id":1,"method":"debug_traceTransaction","params":["<transactionHash>","<options>"]}'
const res = await fetch("https://triport.io/rpc/bsc", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer <api-key>" },
  body: JSON.stringify({
  "jsonrpc": "2.0",
  "id": 1,
  "method": "debug_traceTransaction",
  "params": [
    "<transactionHash>",
    "<options>"
  ]
}),
});
const data = await res.json();
import requests
resp = requests.post(
    "https://triport.io/rpc/bsc",
    headers={"Authorization": "Bearer <api-key>"},
    json={"jsonrpc":"2.0","id":1,"method":"debug_traceTransaction","params":["<transactionHash>","<options>"]},
)
print(resp.json())
