WalletConnect (WCT) is a secure open-source protocol that connects cryptocurrency wallets to decentralized applications (dApps). It works by scanning a QR code or clicking a deep link, creating an encrypted connection between the wallet and the dApp.
This allows users to interact with Web3 apps (like Uniswap, Aave, or OpenSea) directly from their wallet without exposing private keys. It supports multiple blockchains and is widely adopted across the crypto ecosystem.
Key Points:
Secure: End-to-end encrypted, private keys never leave the wallet.
Multi-chain: Works across Ethereum, BNB Chain, Polygon, and others.
User-Friendly: Connects via QR or link; no need for browser extensions.
Widely Supported: Compatible with wallets like MetaMask, Trust Wallet, Coinbase Wallet, etc.
