Let me try to specify my question with an example:
Consider that there are 4 accounts ( AccountA and AccountB and AccountC (Taged as Store) and and AccountD (Taged as Night Club)), and AccountA wants to send let's say $100 to AccountB with a specified condition (i.e. $100 can be spent only at Accounts taged as Store ).
Can i implement above case?
If i can, how?
