WalletConnect: is a tool that lets you securely link your cryptocurrency wallet to various decentralized applications (dApps) without needing to share your private keys. It's like a bridge that connects your wallet (like MetaMask or Trust Wallet) to the dApp (like a decentralized exchange or a game) so you can interact with them. Instead of copying and pasting wallet addresses or using browser extensions, WalletConnect uses QR codes or deep links for a simpler and more secure connection.
