eth_getTransactionCount on Ethereum Classic
Everything below was measured on 2026-10-13 by calling eth_getTransactionCount on Ethereum Classic through the same endpoint customers use, and is re-measured weekly.
What eth_getTransactionCount does
Returns the number of transactions an address has sent, which is the nonce its next transaction must use. With the pending tag it also counts the address's transactions waiting in the node's mempool.
eth_getTransactionCount on Ethereum Classic: what we measured
On an address that had just sent a transaction in the latest block (0x092b7c8a60f8930783ac2e282ae7419d3c3deb83):
| "latest" | 73,770 |
|---|---|
| "pending" | 73,770 |
Which tag to use
"pending" equalled "latest" for this address when we read it. Use "pending" for the next nonce anyway: it covers your own transactions that are sent but not yet mined. On a chain with a few seconds per block, sending twice in one block is common.
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_getTransactionCount","params":["0x092b7c8a60f8930783ac2e282ae7419d3c3deb83","pending"]}'import { createPublicClient, http } from "viem";
const client = createPublicClient({
transport: http("https://rpc.swiftnodes.io/rpc/etc?key=YOUR_API_KEY"),
});
const nonce = await client.getTransactionCount({ address, blockTag: "pending" });
// Sending several transactions: let viem track nonces locally
import { nonceManager, privateKeyToAccount } from "viem/accounts";
const account = privateKeyToAccount(key, { nonceManager });Other methods on Ethereum Classic

Frequently asked questions
Does Ethereum Classic support eth_getTransactionCount?
Yes. eth_getTransactionCount answered on the SwiftNodes Ethereum Classic endpoint when our weekly probe called it through the customer path (2026-10-13).
How do I get the next nonce on Ethereum Classic?
eth_getTransactionCount(address, "pending"). For several transactions in a row, increment locally.
Ethereum Classic endpoints, live block height and WebSocket status are on the Ethereum Classic RPC page.
One key covers every chain we serve, and SwiftNodes has a free tier.
