trace_replayBlockTransactions

Last updated:

trace_replayBlockTransactions replays all transactions in a single block in order, against the state as it existed at that block, and returns one trace result per transaction. Unlike a plain receipt, the result can include the full internal call tree, a step-by-step virtual-machine trace, and the set of state slots each transaction read and wrote.

You choose how much detail to return with the traceTypes array. Request only what you need: vmTrace in particular produces very large payloads (one entry per executed opcode) and is the most expensive mode to compute. For most call-graph analysis, ["trace"] alone is enough.

Use this method for block-level forensics — reconstructing internal transfers, auditing MEV activity, or diffing state across a whole block — when per-transaction calls would be too chatty. This is a pro-tier method; requests authenticated with a lower tier are rejected with -32002.

Examples

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