[Ethereum] How to get ETH contract balance with Ethers.js

balancescontract-invocationetherethers.js

I am trying to get the ETH balance of a contract:

const balance = await contract.getBalance();

but it fails:

TypeError: contract.getBalance is not a function

What I do wrong and how to fix the error?

Best Answer

getBalance is a function of the Ether.js blockchain provider object, it is used this way :

const balance = await provider.getBalance("address");

Note that you can use contract.address to obtain the address of the contract instance.

[Ethereum] How to get ETH balance with pending transaction

I dont see any direct way to get this. But you can try web3.eth.filter with specifying the account address.

Parameters

String|Object - The string "latest" or "pending" to watch for changes in the latest block or pending transactions respectively. Or a filter options object as follows:
fromBlock: Number|String - The number of the earliest block (latest may be given to mean the most recent and pending currently mining, block).
toBlock: Number|String - The number of the latest block (latest may be given to mean the most recent and pending currently mining, block).
address: String - An address or a list of addresses to only get logs from particular account(s).
topics: Array of Strings - An array of values which must each appear in the log entries. The order is important, if you want to leave topics use null, e.g. [null, '0x00...'].

[Ethereum] Cant get address balance using web3js

The issue with your testnet url, https://ropsten.etherscan.io/ is not running eth client.

Find below code to connect ropsten node.

const testnet = 'https://ropsten.infura.io/';
const walletAddress = '0x8690F1feff62008A396B31c2C3f380bD0Ca6d8b8';

const web3 = new Web3(new Web3.providers.HttpProvider(testnet));
var balance = web3.eth.getBalance(walletAddress); //Will give value in.
balance = web3.toDecimal(balance);

I am getting value. Now balance will give as wei. Check web3 api method's for the same.
