@WalletConnect ensuring the identification, security, and functionality of your decentralized application (dApp).
Reasons for the importance of projectId
Identification and authorization: Each projectId serves as a unique identifier for your dApp in the WalletConnect network. When your application sends a connection request to a wallet, this key allows the protocol to instantly identify the source of the request. This ensures that the request originates from a legitimate application and not from an attacker.
Security: projectId is the first line of defense. It allows:
Protect against phishing: Wallets can verify whether the connection comes from a known and registered application, warning users about potentially dangerous sites.
Manage permissions: Thanks to the projectId, your dApp can request only the permissions it needs to operate, adhering to the principle of least privilege.
Management and analytics: WalletConnect Cloud, a cloud platform for developers, uses projectId to provide access to essential tools:
Key management: You can generate and revoke keys, controlling access.
Usage analytics: WalletConnect provides developers with data on the number of connections, user activity, and other metrics, helping them optimize their dApp.
Push notification service: For mobile wallets, projectId is required to send push notifications. This enables wallets to inform users about incoming transaction signing requests, even if the app is inactive in the background, significantly improving the user experience.
Without a projectId, proper connection initialization is not possible, making this key an indispensable element for any dApp seeking secure and reliable interaction with wallets.#Walletconnect
