code examplesconst Web3 = require("web3");
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);
async function getBalance(address, block) {
const balance = await web3.eth.getBalance(address, block)

eth_getBalance
is to check the balance of an account for a program that scans the balance periodically and fills up the account when the balance drops below a certain value.
Here’s an example of how you can achieve this in web3.js:
const Web3 = require("web3");
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);
const accountAddress = '0x0938C63109801Ee4243a487aB84DFfA2Bba4589e';
const minimumBalance = 10000000000000000000; // 10 ETH in wei
async function checkBalance(address) {
const balance = await web3.eth.getBalance(address, 'latest');
return balance;
}
async function fillUp(balance) {
const minimumConverted = web3.utils.fromWei(String(minimumBalance), 'ether');
if (balance < minimumBalance) {
console.log(`The balance of the account ${accountAddress} is below ${minimumConverted} ETH.`);
console.log(`Sending more funds...`)
// Call another function to fill up your account
} else {
console.log(`The balance of the account ${accountAddress} is above ${minimumConverted} ETH.`);
console.log(`No need to send more funds.`)
}
}
async function main() {
const balance = await checkBalance(accountAddress);
const balanceInEth = web3.utils.fromWei(balance, 'ether');
console.log(`The balance of the account ${accountAddress} is ${balanceInEth} ETH. \n`);
await fillUp(balance);
}
main();
accountAddress
variable holds the address for which you want to check the balance. The minimumBalance
variable holds the minimum balance in Wei you want to check against.
The checkBalance
function takes an address as an argument and returns the balance of the account in Wei. The fillUp
function takes the balance as an argument and converts the minimum balance from Wei to ETH using the fromWei
method from the web3.js utility library, and checks if the balance is below the minimum balance.
checkBalance
and fillUp
functions to convert the balance from Wei to ETH using the fromWei
method, and log the balance and the result of the check to the console.
In summary, this script allows you to easily check the balance of an account on the Arbitrum network and take action if the balance falls below a specified minimum.The account balance.
