Expand Token

Contains the ExpandToken contract and convenience wrappers for executing views and transactions.

Environments

There are three possible environments, each with their own .env file and set using NODE_ENV. For example:

NODE_ENV=ropsten npm run migrate --network ropsten

NODE_ENV=ropsten node scripts/foobar.js

NODE_ENV=production npm run migrate --network live

NODE_ENV=production node scripts/foobar.js

Running Scripts

Add scripts to the scripts/ directory, using scripts/template.js as a guide:

const runScript = require('../src/runScript');

runScript(async (token, ownerAddress, web3) => {
  // Script here
})
  .then(() => console.log('done'))
  .catch(err => console.error(err));

The token instance that's passed to your script has the following async methods derived from the contract:

Views

View methods return the relevant values.

balanceOf(address)

allowance(owner, spender)

Transactions

Transactions return logged event on success, and throw errors on failure.

transfer(to, value)

transferFrom(from, to, value)

approve(address, value)
