To facilitate crypto top-ups, you'll be using the Channels functionality of our API. A channel is essentially a permanent address that is unique to each of your end-users, that can freely accept top-ups without the need to create a new payment each time - allowing your customers to send crypto whenever they want to top up.
The first time your end-user chooses to top up with crypto, you will need to create a channel for them that you store against their user ID in your system - so that you can display the correct address to them each time they query where to send funds to.
After you've created a channel and they proceed to top up, you'll see transactions use the following states:
|No||A new cryptocurrency transaction has been detected at the channel address. BVNK creates a ChannelPayment transaction with the status of |
|Yes||The cryptocurrency transaction has got the required number of confirmations on the Network. BVNK updates the ChannelPayment status from |
Be careful not to create a channel that is used by multiple of your end-users as you won't be able to reconcile who sent the funds. Cryptocurrency transactions, unlike fiat, do not have references sent over the blockchain, so by giving each customer a channel you can reconcile their top-ups against their account on your platform.
