Code Snippet#

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

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

console.log('Connected to', (await api.rpc.system.chain()).toString());

Usage Notes#

  • Pair with system_properties to double-check token symbol and decimals.
  • Automation scripts can fail fast if the returned string is not Manta Parachain.
