Extension of Master-Storage: Coin Items
Originally posted by Arrex
After the idea of the master-storage for all Game-Accounts of one user, there's still no working banking. Even though it's probably worked on (we already have a "banking"-Button at the interface) a workaround for the time would be an npc to convert a set amount of money into a coin-item of set value (bronze coin, silver coin, gold coin). Those can be stored and exchanged for the same amount of zeny they were paid for.
The exchange-transactions zeny->item/item->zeny of course would need to be dialog-based to avoid a change of value via Overcharge/Discount.
