## payment

Use memo to mark a order, for example:
```
$ order_id=01944f23-df45-75bb-a411-d05dd819c92a
$ owner=BSzG62Khqw5pbbWPmoe8iZekExekFQBJmjYhiXhcVvtS
$ solana transfer ${owner} 0.1 --with-memo ${order_id}
```
SPL Token:
```
$ mint=Gh9ZwEmdLJ8DscKNTkTqPbNwLNNBjuSzaG9Vp2KGtKJr
$ spl-token transfer ${mint} 0.1 ${owner} --with-memo ${order_id}
```
