# Softbank
**A Soft Bank To Handle your Financal Accounts**
***This Module has the following banking functions available***
Account Management ( a genserver that acts as the gateway between you and your accounts backed by a double entry accounting system )
Currency Conversion ( with auto update on conversion rates )
Custom Currencies ( added to the accounting system automatically)
Transfers(the producers send amount will be converted to match the recievers account currency type)
Typically the Account Management genserver would be considered an anti pattern, however I needed a way to persist the state of my accounts ledgers in order to decouple accounting from user management.
This allows an accounts ledger state to be persisted for a ttl, when some other system process needs also to use the account ledger data the ttl is reset and state persisted until timeout occurs.
