# 1st Generation: Reloadable Prepaid Cards

The first generation of crypto debit cards emerges as a simple and practical way for users to spend their cryptocurrencies. These cards are essentially fiat prepaid cards that can be topped up with digital assets. Here’s how they function:

* Custodial Control: Users convert their cryptocurrencies into fiat currencies through a custodial provider.
* Pre-Funded Accounts: Fiat funds are then deposited into a pre-funded account linked to the card.
* Usage: The card can be used for transactions just like any other prepaid card, with funds preloaded and ready to spend.

While these cards provide a straightforward way to use crypto for everyday purchases, they require users to trust a central entity to manage and hold their funds. This custodial setup poses inherent risks and limits the appeal to users who prefer control over their assets.
