trace_block on Fraxtal
Measured 2026-10-11 by our weekly probe, which calls trace_block through the same Fraxtal endpoint customers use.
What trace_block does
Returns Parity-style traces for every transaction in a block: internal calls, contract creations and value transfers. Indexers use it to reconstruct internal ETH movements that receipts do not show.
trace_block on Fraxtal: what we measured
- Default Fraxtal routing keeps state for roughly the last 1,000,000 blocks (about 23.1 days of Fraxtal history). Tracing a block older than that needs historical state. Add &archive=1 to send the request to archive upstreams (paid plans).
Example request
curl -s https://rpc.swiftnodes.io/rpc/fraxtal?key=YOUR_API_KEY \
-X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"trace_block","params":["latest"]}'import { createPublicClient, http } from "viem";
const client = createPublicClient({ transport: http("https://rpc.swiftnodes.io/rpc/fraxtal?key=YOUR_API_KEY") });
// Any JSON-RPC method, typed loosely: trace_block on Fraxtal
const result = await client.request({
method: "trace_block",
params: ["latest"],

Frequently asked questions
Does Fraxtal support trace_block?
Yes. trace_block answered correctly on the SwiftNodes Fraxtal endpoint in our weekly method probe (2026-10-11), which sends real requests through the customer path.
Are there limits on trace_block on Fraxtal?
Default Fraxtal routing keeps state for roughly the last 1,000,000 blocks (about 23.1 days of Fraxtal history). Tracing a block older than that needs historical state. Add &archive=1 to send the request to archive upstreams (paid plans).
Fraxtal endpoints, live block height and WebSocket status are on the Fraxtal RPC page.
