A currency is a more general purpose token, identified uniquely using a currency code and also using the unique 64 bit transaction id of the asset issuance transaction. Use the getCurrency API to retrieve the currency properties. Depositing and withdrawing currencies is done using the transferCurrency transaction, currency transfer transactions are identified by type=5 and subType=3. When dealing with currencies, make sure the currency is issued, i.e. the blcokchain passed the issuance height of the currency and that it is not deleted.
