Cryptocurrency Integration in Marketplace App

Hello all, I was curious if there were any restrictions on listing an app that integrates with an ERC20 token? Looking at the listing requirements, it doesn’t mention anything about crypto. So for example, writing an app where users could connect with a wallet vote on issues with an ERC20 token. Would that be in line with the listing regulations? Basically, not trying to write a bunch of code and then later realize it’s against the rules for a marketplace app. Thanks!
