It is an open-source protocol that connects digital wallets and decentralized applications (dApps) in a secure and user-friendly way. Instead of entering private keys directly into websites or applications, WalletConnect allows users to scan a QR code or use a deep link to confirm the connection. This mechanism provides an additional layer of protection because it keeps private keys within the wallet only, without sharing them with any third party.

WalletConnect is widely used in decentralized trading platforms, decentralized finance (DeFi) applications, and non-fungible token (NFT) markets. Once connected, users can sign transactions and approve smart contracts directly from their wallet, making the trading experience and interaction with the blockchain easier.

One of its features is that it supports multiple wallets such as Trust Wallet, MetaMask, and Coinbase Wallet, and works across different operating systems. This flexibility has made it a standard for communication between wallets and applications. Thanks to its simplicity and security, WalletConnect is an essential tool in promoting the adoption of Web3 and facilitating access to the decentralized digital economy.
