Do my customers hold a balance at KemyCard?
Do my customers hold a balance at KemyCard?
No. A wallet is a collection address for one of your customers. Each deposit is credited, net of the deposit fee, to your collected balance for that blockchain, and reported to you by webhook with the customer and the amount. The balance of each customer is kept in your own system. See Crypto wallets.
