Cards

The product of virtual prepaid cards backed by cryptocurrencies is aimed at businesses and uses stablecoins on the Polygon blockchain as collateral. Each card is linked to a stablecoin wallet, but the conversion to dollars is automatic and done at a 1:1 ratio, making it easier to use the card in traditional payment ecosystems.

The cards are Visa and can be used for payments at any merchant that accepts Apple Pay, Google Pay, or e-commerce platforms. They are also protected by the 3DS security system to prevent fraud.

There are two types of cards:

1. Top Up: In this model, users can load funds onto their card through a dedicated deposit wallet created specifically for this purpose.
2. External Authorization: In this case, the business systems integrate with the client's systems through webhooks, which have 1200 ms to approve or decline the purchase based on the client's rules.

Each business can generate as many cards as they have available in their pack, offering flexibility to meet their users' needs.

The product also includes a holding wallet, which contains the funds that guarantee all card purchases. For a purchase to be made, there must be sufficient funds in this wallet; otherwise, the transaction will be declined.

Funds in the holding wallet can be withdrawn to external wallets to be used at the client's discretion. However, a minimum balance will remain frozen to ensure that at least one transaction can be made in the system. This guarantees that there will always be enough funds to cover some card transactions.

This product combines the convenience of traditional cards with the flexibility of blockchain technology, providing businesses with a modern and efficient solution for managing payments backed by cryptocurrencies.
