💰Get the native balance of a Signer

In this section we'll learn how to get the native balance for a Signer using polkadot.js API

Checking the native balance of a Substrate address using Polkadot API

      const wsProvider = new WsProvider("wss://rpc.polkadot.io");
      const api = await ApiPromise.create({ provider: wsProvider });
      const substrateAddress = ""
      let balance = await api.query.system.account(substrateAddress);

As you can see, the wsProvider is defining the chain on which the native balance will be fetched.
