Parameters
This method takes no parameters.Returns
Returns the client version as a string (e.g., “HyperEVM/v1.0.0”).cURL example

-d '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":1}' \

from web3 import Web3
w3 = Web3(Web3.HTTPProvider("YOUR_CHAINSTACK_ENDPOINT"))
client_version = w3.client_version
print(client_version)
import { JsonRpcProvider } from "ethers";
const provider = new JsonRpcProvider("YOUR_CHAINSTACK_ENDPOINT");
const clientVersion = await provider.send("web3_clientVersion", []);
console.log(clientVersion);
import { createPublicClient, http } from "viem";
const client = createPublicClient({
transport: http("YOUR_CHAINSTACK_ENDPOINT"),
});
const clientVersion = await client.request({ method: "web3_clientVersion" });
console.log(clientVersion);
Use your own endpoint in your code. The code examples use a placeholder Chainstack endpoint (YOUR_CHAINSTACK_ENDPOINT) — replace it with your own Hyperliquid node endpoint from the Chainstack console. The curl above uses a shared public endpoint for quick checks only; do not use it in production.
