+#### Allowed Wallets ([#8][i8])
+
+Sometimes you want to mark certain wallets as allowed so that when the `pay()` method is called, the system does not attempt to charge other wallets, a possible use case is an escrow system, the `$allowedWallets` param of the pay method allows you to do just that.

+$user = auth()->user();

+When the `$allowedWallets` param is provided and is not an empty array, the system would attempt to charge only the wallets specified in the array.

+#### Transaction Notes ([#8][i8])

+In a case where you want to enter descriptions for a particular transaction, the `$note` param allows you to provide information about why a transaction happened.
