Installation:

npm i simple-erc20

Usage:

  import SimpleERC20 from 'simple-erc20'
  
  const token = new SimpleERC20('0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2');
  token.name().then(console.log);
  //Should print Wrapped Ether
  
  const asyncFunction = async () => {
    console.log(await token.symbol())
  };
  
  asyncFunction();
  //Should print WETH

The SimpleERC20 function can receive three parameters.

1. A ERC20 token address
2. The network name or id Ethereum network (optional, defaults to main)
3. An existing web3 object to wrap (optional)

The resulting object currently provides data from the basic erc20 public function calls.
