🏗️Technical Architecture

The 1FUEL debit and credit cards are powered by a robust backend system that integrates cryptocurrency wallets with traditional payment networks. The key components of this architecture include:

Real-Time Conversion Engine

Conversion Logic: When a user makes a purchase, the conversion engine automatically converts the required amount of cryptocurrency from the user’s wallet to fiat at the current exchange rate.

API Integration: The conversion engine connects to various exchange APIs to fetch real-time prices and execute the conversion at the most favorable rate.

Transaction Processing: Once the conversion is complete, the fiat amount is processed through the traditional payment network to complete the transaction with the merchant.

Payment Network Integration

Card Issuance: 1FUEL partners with major payment networks like Visa or Mastercard to issue both virtual and physical cards.

Security Features: The cards include multiple security layers, such as EMV chip technology, 2FA (Two-Factor Authentication), and fraud detection systems, ensuring that transactions are secure.

User Interface

Wallet Integration: Users can view their card balance, transaction history, and manage their cards directly from the 1FUEL wallet interface.

Spending Controls: Users can set spending limits, freeze their cards, or manage multiple cards from a single interface.
