EAC Counter

A library that fetches the amount of ETH (and USD) transferred using the Ethereum Alarm Clock.

Installation

npm install eac-counter

Usage

import EacCounter from 'eac-counter';
const eacCounter = new EacCounter({
  // Needed for fetching amount of USD transferred, get an API key from https://nomics.com/
  nomicsApiKey: '<nomics_api_key>',
  // Needed for fetching amount of ETH transferred, get an API key from https://etherscan.io/
  etherscanApiKey: '<etherscan_api_key>',
});

// Optional: Needed to fetch the amount of USD transferred
await eacCounter.enableUSDFetching();

const { eth, usd } = await eacCounter.getTotalTransferred();
console.log(eth);
console.log(usd); // This will be null if enableUSDFetching() is not called

Browser usage

To use this library in the browser, download and import the browser-compatible file into your HTML file.

<script src="eac-counter.browser.js"></script>

This will expose the EacCounter to the window object. You can then use the following code to fetch the counter:

const eacCounter = new EacCounter({
  nomicsApiKey: '<nomics_api_key>',
  etherscanApiKey: '<etherscan_api_key>',
});
eacCounter.enableUSDFetching().then(function () {
  eacCounter.getTotalTransferred().then(function (value) {
    console.log(value.eth);
    console.log(value.usd);
  });
});
