In this section we'll learn how to get the some basic network information using polkadot.js API
Check the network information using Polkadot API
// Import the Polkadot API
import { ApiPromise, WsProvider } from '@polkadot/api';
async function connectAndFetchChainInfo() {
// Create a connection to the Polkadot network via websocket
const polkadotWsProvider = new WsProvider('wss://rpc.polkadot.io');
// Create a new instance of the Polkadot API
const polkadotApi = await ApiPromise.create({ provider: polkadotWsProvider });
// Retrieve information about the Polkadot chain
const polkadotChainInfo = await polkadotApi.registry.getChainProperties();
console.log(polkadotChainInfo);
// For Polkadot, this would print
// {ss58Format: 0, tokenDecimals: [10], tokenSymbol: [DOT]}
}
connectAndFetchChainInfo().catch(console.error).finally(() => process.exit());
