How can mobile wallets improve the cryptocurrency user experience?

Currently, many users prefer to use mobile wallets to manage their cryptocurrencies. These wallets are more convenient and natural to use, as they allow you to hold your cryptos directly on your phone. Valora is one of the mobile wallets facilitated by the Celo ecosystem, which allows for a more user-friendly interaction with smart contracts, payments, and transfers. To achieve this integration, it is critical to connect our apps and contracts with mobile wallets using key tools such as Wallet Connect and Contract Kit.

How to connect Wallet Connect and your application in Visual Studio Code?

The Wallet Connect integration facilitates the interaction between applications and mobile wallets. The first step is to make sure you have Wallet Connect installed. There is an instruction file in the course code repository that will guide you through the necessary adaptations based on your operating system and version of Node.

What is the role of the Wallet Connect Provider?

Once Wallet Connect is installed, the Wallet Connect Provider reference must be incorporated in the application's React file. This reference is essential to configure the provider. Subsequently, you must use a function that configures this provider each time a user clicks on a button. Such a function facilitates the connection of the application with the Forno network or the Alfajores network, depending on the user's selection in his wallet.

What happens once the Wallet Connect Provider is enabled?

The next step is to call the Provider Enable method, which displays a QR code on the screen. The user can scan this code, obtaining authorization to perform certain actions. For example, you will be able to make transfers from Zerogold to a predefined wallet in the application. This authorization is obtained thanks to the fact that the transaction is performed with test cryptocurrencies, avoiding the use of real cryptos.

How to validate the connection and execute transactions from a mobile wallet?

After establishing the connection using the QR code, it is possible to execute transactions from the mobile wallet.

1. Graphical interface: The application must have a button that enables the connection via Wallet Connect.
2. Scanning the QR code: Once connected, the user can use his cell phone to scan this code.
3. Wallet Connect: The mobile wallet such as Valora asks if the user wants to connect through the application.
4. Transaction confirmation: Once allowed, a PIN is requested from the user to authorize and process the transaction.

The execution of a transaction is validated when the balance reflects the transfer in the corresponding wallet.

What are the advantages of communication between smart contracts and mobile wallets?

The integration of smart contracts with mobile wallets results in an enhanced user experience:

• Simple and familiar use for new and experienced users.
• Increased convenience and security when handling cryptocurrencies from mobile.
• Possibility of fast and secure transfers using proof-of-stake cryptocurrencies.

This advance is essential for the development of decentralized applications on the Redset. Developers who implement these features will offer added value to their users, encouraging wider adoption of cryptocurrencies. If you've made it this far, you're ready to apply these skills to your projects and continue exploring the power of mobile wallets in blockchain technology.
