Query Balance

Use Web3.js to Query Balance on Clover

We can easily do this by leveraging the Ethereum compatibility features of Clover.

First let's create a file balance.js under the project we've created. Here we just query the balance of the genesis account, and the genesis account is endowed with 10,000,000 ETH by your local Clover node under the development mode. To get the balances of the account, we need to make an asynchronous function that uses the web3.eth.getBalance(address) command. We can take advantage of the web3.utils.fromWei() function to transform the balance into a more readable number in ETH.

The file looks like this:

const Web3 = require('web3')

const web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:9933'));
const GENESIS_ACCOUNT = '0xe6206C7f064c7d77C6d8e3eD8601c9AA435419cE';

async function getBalance(account) {
  const balance = await web3.eth.getBalance(account);
  const balanceOfEther = web3.utils.fromWei(balance, "ether");
  console.log(`${account} has balance: ${balanceOfEther} ETH`);
}

getBalance(GENESIS_ACCOUNT);

Running the Script

You can run the above script using command :

node balance.js

The output of the execution is as following:
