Apps facilitating cryptocurrency trading need to come from properly licensed providers where required, wallet apps have to be from a developer enrolled as an organization, and actual on-device crypto mining isn't allowed at all — only cloud-based mining services can be offered.
Most often caught by an app attempting on-device mining, or a crypto exchange app submitted from an individual developer account rather than a licensed organization.
"Your app facilitates the mining of cryptocurrency directly on-device, which is not permitted per guideline 3.1.5."
Guideline 3.1.5 sets out requirements for apps that deal with cryptocurrency. Wallet apps must be offered by organisations, exchanges and trading services need appropriate licences where required, and mining on the device itself is not allowed. Cloud-based mining services are treated differently. Because financial rules differ by country, a developer's licensing and regional availability are part of the review.
Cryptocurrency apps can involve real money, regulatory obligations and the risk of fraud or loss for users. Apple therefore expects the party behind the app to be accountable, which is why organisations and licences are emphasised. The ban on on-device mining protects battery life, device health and users who might not understand that their phone is being used to generate coins for someone else.
Apple expects wallet apps to come from organisations.
