# Address Book

Managing wallet addresses for Crypto and Fiat Withdrawals

{% hint style="info" %}
Adding incorrect withdrawal addresses, or tag/memo may result in the loss of your coins.
{% endhint %}

### Address Book

Users can use the *Address book* function to streamline, secure, and automate their cryptocurrency and fiat address management. The address book is used to manage both the counterparty and user’s own addresses. The platform enables users to save, whitelist, and manage both wallet addresses and bank details, reducing the risks associated with manual entry.

To send funds to counterparties/third parties, the user can use Aquanow's *Pay* product. Users will see *Self* if they are not enabled for Payment products. If users are enabled for payment products, they will be able to see both *Self* and *Counterparty addresses* in the Address book landing page.

{% hint style="info" %}
It is possible to enable the customer's account to only withdraw to whitelisted addresses, or a combination of freeform addresses and whitelisted addresses. If withdrawal to whitelisted addresses is selected, any address that is added will be in cooldown for 24 hours, implying that this address cannot be used for 24 hours after being added.
