If you're thinking of implementing Stripe's crypto onramp into your app, don't. You'll no longer be able to accept fiat. It's a 3 week process to get reapproved to accept fiat, and it's still not guaranteed.

Was using stripe for payments and I received a cancellation notice similar to this one.. my app only made it to testnet so I didn’t suffer

Stripe cancellation notice is concerning, but not harmful if app is still in testnet
