Optimal Development Path for Decentralized Applications (dApps)

**Optimal Development Path for Decentralized Applications (dApps)**

Developing decentralized applications (dApps) that interact with multiple blockchains and wallets presents significant challenges. Developers must possess a deep understanding of various technologies and integrate with different blockchain environments, which increases both complexity and costs.

The simplest solution is to decouple blockchain and wallet functionalities from the application itself. This allows developers to focus solely on the logic and user interface of their application, leveraging third-party blockchain and wallet services for integration.

Currently, the most common method for connecting to wallets is via WalletConnect. However, the user experience is suboptimal, as users are often required to switch between the application and the wallet, making the process cumbersome. Moreover, WalletConnect primarily supports Ethereum and similar blockchains, leaving other networks, such as Bitcoin, unsupported.

A superior connection tool, **Cool-connect** (available at [https://www.npmjs.com/package/cool-connect](https://www.npmjs.com/package/cool-connect)), offers a more seamless wallet integration experience. It enables automatic wallet connections within the wallet environment, eliminating the need for manual intervention. This approach makes the application function almost as if it were an inherent feature of the wallet, including automatic language adaptation.

Cool-connect is extremely easy to implement. However, the number of wallets currently supporting Cool-connect is limited, with **pay.cool** being the best-supported wallet at present.
