debug_traceCall on ApeChain

Measured 2026-10-04 by our weekly probe, which calls debug_traceCall through the same ApeChain endpoint customers use.

What debug_traceCall does

Executes a call against a block's state and returns its execution trace (with a tracer such as callTracer), without sending a transaction. It is the standard way to see what a call would do internally before you submit it.

debug_traceCall on ApeChain: what we measured

• Default ApeChain routing keeps state for roughly the last 1,000,000 blocks (about 12.1 days of ApeChain history). Tracing against a block older than that needs historical state. Archive routing did not measure as available on this chain.

Example request

curl -s https://rpc.swiftnodes.io/rpc/apechain?key=YOUR_API_KEY \
  -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"debug_traceCall","params":[{"to":"0x0000000000000000000000000000000000000000","data":"0x"},"latest",{"tracer":"callTracer"}]}'

import { createPublicClient, http } from "viem";

const client = createPublicClient({ transport: http("https://rpc.swiftnodes.io/rpc/apechain?key=YOUR_API_KEY") });

// Any JSON-RPC method, typed loosely: debug_traceCall on ApeChain
const result = await client.request({
  method: "debug_traceCall",
  params: [{"to":"0x0000000000000000000000000000000000000000","data":"0x"},"latest",{"tracer":"callTracer"}],
});
