Quick Check with @polkadot/api

import { ApiPromise, WsProvider } from '@polkadot/api';

const provider = new WsProvider('wss://api-manta-atlantic-mainnet.n.dwellir.com/YOUR_API_KEY');

const version = await api.rpc.system.version();
console.log('Node version', version.toString());

Usage Notes

• Pair with state_getRuntimeVersion to track both runtime and binary upgrades.
• During maintenance windows, validate that all nodes report the same version before returning them to rotation.
