The transaction safety measures include but aren’t limited to encrypting sensitive data, verification of user accounts and signatures, and integrations of blockchain security protocol, etc.
#4. Integration with Payment Gateways
This feature enables users to perform the payments directly from their crypto wallets, through the integrated external payment processors or gateways for cryptocurrencies. Crypto-based technologies work similarly to the standard payment processor gateways and acquire bank credit cards and are commonly applied to make transactions more simple without compromising their security.
#5. Efficient Address Management
Powerful address management functionality allows crypto users to ease wallet address tracking and facilitate their identification. However, along with the technical aspects, developers also need to ensure the system provides a convenient design and user-friendly experience for managing crypto addresses.
#6. Integrations with the Paper Wallets
Importing paper wallets allows crypto holders to transfer funds between a physical paper wallet and the digital crypto wallet app. Yet, similarly to the crypto exchange security features, paper wallet integration should be handled carefully due to its high relevance to sensitive user information and financial data.
#7. QR Code Scanning
This function is mainly used to simplify the process of sending and receiving cryptocurrencies. Users can scan QR codes to input wallet addresses, conduct transactions, or log in to their crypto wallets through any mobile or desktop device. The QR code scanning integration is relatively straightforward and features plenty of established libraries and APIs available for developers.
#8. Automated Session Logout
This functionality can provide the add-on security layer for your digital wallet app, ensuring they’re safe and can be accessed only by authorized parties with specific permissions. Once the session is ended, the system will automatically log you out, confirming the safety of the in-app processes and crypto manipulations.
