exc-balance-checker

Code for checking an address' balance with Eximchain's ERC20 token.

Usage

Install via:

npm install --save exc-balance-checker

Import the main checker class:

import BalanceChecker from 'exc-balance-checker';

Configure internal provider and you're ready to check balances:

const checker = new BalanceChecker("https://mainnet.infura.io/...");

The constructor takes an optional second options argument. It is an object which can have keys timeout, user, password, and headers, corresponding to the additional arguments which can be passed to the web3.HttpProvider(). This is useful for setting the CORS Access-Control-Allow-Origin header of your provider URL, as Firefox and Safari will block requests which do not have that set.

checker.balanceOf(<myAddress>).then((myBalance) => {
    // Use myBalance within here
})

// or

var myBalance = await checker.balanceOf(<myAddress>);
