eth_sendRawTransaction on Ethereum Classic

Everything below was measured on 2026-10-13 by calling eth_sendRawTransaction on Ethereum Classic through the same endpoint customers use, and is re-measured weekly.

What eth_sendRawTransaction does

Submits a signed transaction to the network and returns its hash. The node checks the signature, chain ID, nonce and balance first, and returns an error string instead of a hash when any check fails, which is the text your app has to handle.

Example request

curl -s https://rpc.swiftnodes.io/rpc/etc?key=YOUR_API_KEY \
  -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_sendRawTransaction","params":["0x02f8..."]}'

import { createPublicClient, http } from "viem";

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

try {
  const hash = await client.sendRawTransaction({ serializedTransaction: signed });
  const receipt = await client.waitForTransactionReceipt({ hash });
} catch (e) {
  const msg = String(e?.details ?? e?.message);
  if (/insufficient funds/i.test(msg)) { /* ask the user to top up */ }
  else if (/nonce too low|already known/i.test(msg)) { /* already sent: look up by hash */ }
  else throw e;
}
