trace_transaction on Monad
Measured 2026-10-04 by our weekly probe, which calls trace_transaction through the same Monad endpoint customers use.
What trace_transaction does
Returns the Parity-style trace of one transaction: every internal call, creation and value transfer it caused. It is the usual tool for debugging a transaction after it has been mined.
What to use instead on Monad
Monad did not serve the trace_* namespace in our probe, which is common on OP Stack and zk chains. The debug_* namespace works on Monad: use debug_traceTransaction with the callTracer instead.
Example request
curl -s https://rpc.swiftnodes.io/rpc/monad?key=YOUR_API_KEY \
-X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"trace_transaction","params":["0x0000000000000000000000000000000000000000000000000000000000000000"]}'import { createPublicClient, http } from "viem";
const client = createPublicClient({ transport: http("https://rpc.swiftnodes.io/rpc/monad?key=YOUR_API_KEY") });
// Any JSON-RPC method, typed loosely: trace_transaction on Monad
const result = await client.request({
method: "trace_transaction",
params: ["0x0000000000000000000000000000000000000000000000000000000000000000"],

Frequently asked questions
Does Monad support trace_transaction?
Not on our Monad upstreams: trace_transaction failed in our weekly method probe (2026-10-04). Monad did not serve the trace_* namespace in our probe, which is common on OP Stack and zk chains. The debug_* namespace works on Monad: use debug_traceTransaction with the callTracer instead.
Monad endpoints, live block height and WebSocket status are on the Monad RPC page.
One key covers every chain we serve, and SwiftNodes has a free tier.
