According to Consensys, MetaMask has over 30 million monthly active users, highlighting its widespread adoption.
- WalletConnect: An open-source protocol for connecting dApps to mobile wallets using end-to-end encryption by scanning a QR code.
Practical Example: Integrate WalletConnect into your dApp to allow users to connect their mobile wallets for a secure and seamless experience.
Benefits: Supports multiple wallets, improves user experience, and enhances security.
Ceramic Network
- Ceramic is a decentralized data network that allows you to create and manage portable data profiles.
Practical Example: Use Ceramic to build decentralized identity solutions, user profiles, and social graphs.
Benefits: User-controlled data, portable identity, and interoperable data models.
Web3 Development Platforms and APIs
These platforms provide comprehensive services and APIs that simplify the development process of Web3 applications.
Alchemy
- Alchemy is a blockchain development platform that provides APIs, tools, and infrastructure for building reliable and scalable dApps.
Practical Example: Use Alchemy’s Enhanced APIs for reliable transaction monitoring and data retrieval.
