The same API key works here and on BNB Smart Chain mainnet, and testnet requests count toward your plan like any other request. The free plan includes testnets. Going to mainnet means changing bsc-testnet to bsc in the URL.

import { createPublicClient, http } from "viem";
import { bscTestnet } from "viem/chains";

const client = createPublicClient({
  chain: bscTestnet,
  transport: http("https://rpc.swiftnodes.io/rpc/bsc-testnet?key=YOUR_API_KEY"),
});

console.log(await client.getBlockNumber());

About BNB Smart Chain Testnet

The BNB Smart Chain testnet, also called Chapel, is where BSC hardforks and dApps are tested before mainnet. It produced a block about every 0.45 seconds when we measured, in line with BSC mainnet's sub-second blocks.

With blocks that fast, unfiltered eth_getLogs over even 1,000 blocks was refused with "limit exceeded" by the upstream we measured. Filter by contract address and topics.
