one suggestion; since we're using the functional programming paradigm we really like to follow the principles from the style of programming.
one of the suggestion is to use name binding. This applies for functions, as well.
This can be rewritten like this:
const run = async () => {}

prefer const over let. It's nice to keep reference transparency

you can remove this function because it will be inherited from the ERC20Capped

you can use promisify https://nodejs.org/dist/latest-v8.x/docs/api/util.html and then use async/await
