No, that isn’t how it works. MoonPay is a bitcoin exchange, which you don’t have to use. You can just set up an Alby wallet with no KYC.

No...
I think you are confused.
Getalby is a pure lightning wallet, non kyc, custodian.
You dont need moonpay to use it. You need moonpay only if you need to buy btc using fiat.
