JavaScript example

const getNetworkVersion = async () => {
  const response = await fetch('https://hyperliquid-mainnet.core.chainstack.com/YOUR_API_KEY/evm', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      jsonrpc: '2.0',
      method: 'net_version',
      params: [],
      id: 1
    })
  });
  
  const data = await response.json();
  return data.result;
};

// Usage
const networkId = await getNetworkVersion();
console.log('Network ID:', networkId); // "998"

// Verify correct network
const isHyperliquid = networkId === '998';
console.log('Connected to Hyperliquid:', isHyperliquid);

​
Network verification

const verifyNetwork = async () => {
  const networkId = await getNetworkVersion();
  
  if (networkId !== '998') {
    throw new Error(`Wrong network. Expected Hyperliquid (998), got ${networkId}`);
  }
  
  console.log('Connected to Hyperliquid mainnet');
  return true;
};

// Use before important operations
await verifyNetwork();
// Proceed with transactions...

​
Use cases

  • Network verification — Confirm connection to Hyperliquid before transactions
  • Wallet configuration — Configure wallets to recognize Hyperliquid network
  • dApp development — Build network-aware decentralized applications
  • Multi-network support — Support multiple EVM networks with proper identification
