RPC method

trace_transaction on Soneium

Not available on SwiftNodes

Measured 2026-10-11 by our weekly probe, which calls trace_transaction through the same Soneium 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 Soneium

Soneium did not serve the trace_* namespace in our probe, which is common on OP Stack and zk chains. debug_traceCall did not measure as available either, so read what you can from receipts and logs, which are served.

Example request

curl -s https://rpc.swiftnodes.io/rpc/soneium?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/soneium?key=YOUR_API_KEY") });

// Any JSON-RPC method, typed loosely: trace_transaction on Soneium
const result = await client.request({
  method: "trace_transaction",
  params: ["0x0000000000000000000000000000000000000000000000000000000000000000"],

Frequently asked questions

Does Soneium support trace_transaction?

Not on our Soneium upstreams: trace_transaction failed in our weekly method probe (2026-10-11). Soneium did not serve the trace_* namespace in our probe, which is common on OP Stack and zk chains. debug_traceCall did not measure as available either, so read what you can from receipts and logs, which are served.

Soneium endpoints, live block height and WebSocket status are on the Soneium RPC page.

One key covers every chain we serve, and SwiftNodes has a free tier.
