3. Multiple Cryptocurrencies Support
Offering support to multiple cryptocurrencies in a crypto wallet is crucial for enhancing versatility and offering users a comprehensive solution for managing their digital assets.
Moreover, offering multiple cryptocurrency support will help you attract a broad range of audiences that are interested in purchasing, holding, trading, or selling different types of cryptocurrency, such as Bitcoin, Ethereum, Solana, PolkaDot, etc.
4. Push Notifications
A must-have feature that will help your users to stay alerted and notified of different crypto transactions within their wallet, such as failure or completion of transactions and price changes in their held crypto assets.
Push notification is a great way to ensure that users will do not miss any important events and updates throughout an app.
5. Latest Conversion Rates
Users can access the latest conversion rates between different cryptocurrencies and can benefit from Swapping or trading between different cryptocurrencies.
The latest conversion rates feature helps users calculate transaction fees based on ever-changing conversion rates to facilitate payments between different cryptocurrencies with actual and accurate prices.
6. Blockchain-Based Transactions
Enable your users to view their available balance in their entire transaction history in your Web 3 crypto wallet app. Offering blockchain-based transactions will help your users to transfer and receive digital currencies via crypto applications in an entirely fast and tamper-proof manner.
7. Optional Session Logout
The feature will help you enhance the security of your platform. Optional season logout will sign out inactive users from your app after a fixed duration of their inactivity, and they will need to re-login if they want to use the app again.
