eth_getTransactionCount on BNB Smart Chain
Everything below was measured on 2026-10-13 by calling eth_getTransactionCount on BNB Smart Chain 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 BNB Smart Chain: what we measured
On an address that had just sent a transaction in the latest block (0x4848489f0b2bedd788c696e2d79b6b69d7484848):
| "latest" | 73,395,850 |
|---|---|
| "pending" | 73,395,853 |
Which tag to use
"pending" was 3 ahead of "latest": the address had transactions waiting. Use "pending" for the next nonce, or you will reuse a nonce and replace a queued transaction.
Example request
curl -s https://rpc.swiftnodes.io/rpc/bsc?key=YOUR_API_KEY \
-X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"eth_getTransactionCount","params":["0x4848489f0b2bedd788c696e2d79b6b69d7484848","pending"]}'import { createPublicClient, http } from "viem";
const client = createPublicClient({
transport: http("https://rpc.swiftnodes.io/rpc/bsc?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 BNB Smart Chain

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