Module: ERC20

Defined in:
lib/erc20/erc20.rb

Overview

This module makes manipulations with Ethereum ERC20 tokens as simple as they can be, if you have a provider of JSON-RPC and WebSockets Ethereum APIs, for example Infura, GetBlock, or Alchemy.

Start like this:

require 'erc20'
w = ERC20::Wallet.new(
  host: 'mainnet.infura.io',
  http_path: '/v3/<your-infura-key>',
  ws_path: '/ws/v3/<your-infura-key>'
)
puts w.balance(address)

This should print the balance of the ERC20 address.
