WalletConnect
Also known as: Web3 Wallet Bridge, Wallet QR Connect, Mobile Wallet Integration
An open protocol that allows users to connect crypto wallets to decentralized applications securely.
WalletConnect is an open-source Web3 protocol that enables secure communication between decentralized applications (dApps) and crypto wallets. Instead of using browser extensions, WalletConnect lets users scan a QR code or click a link to connect mobile wallets like Trust Wallet, MetaMask Mobile, or Rainbow. It uses end-to-end encryption over a WebSocket connection, ensuring that private keys never leave the user's device. WalletConnect is widely adopted across DeFi, NFT, and Web3 gaming platforms, offering a seamless cross-device user experience for signing transactions and interacting with dApps.
