As the decentralized finance (DeFi) ecosystem continues to grow, users are seeking more seamless, secure, and efficient ways to interact with decentralized applications (dApps). One standout solution that has revolutionized wallet-dApp interaction is WalletConnect — a communication protocol that bridges the gap between mobile wallets and web3 applications.
In this blog post, we will explore what WalletConnect is, how it works, its key features, benefits, supported wallets, security considerations, and how to start using it — with 10 official references from the WalletConnect website.
WalletConnect is an open-source protocol that enables secure communication between decentralized applications and mobile crypto wallets using QR code scanning or deep linking. Introduced in 2018, WalletConnect has since become an industry standard for secure wallet connections across DeFi, NFTs, gaming, and more.
WalletConnect is not a wallet itself but a protocol — a method of communication that allows dApps to interface with crypto wallets without storing private keys or compromising security.
