Depending on which experience you want to offer to your customers, you can choose between one of the following operational modes:
1) Buy/Sell only: By choosing this mode, your customers will be able to buy crypto, keep them with Lirum and sell them whenever they want. They won't be able to send or receive crypto to/from the blockchain.
2) Buy/Sell + Send: When choosing this mode, your customers will also be able to send the coins they bought to an address in the blockchain.
3) Full support: This is the full experience. It adds the ability for your customers to receive payments from the blockchain.
