Introduction
Decentralized applications (DApps) unlock endless possibilities for leveraging your cryptocurrency beyond holding (HODLing). From decentralized finance (DeFi) platforms to blockchain games, interacting with DApps requires a secure wallet connection. WalletConnect simplifies this process by enabling encrypted links between your wallet and DApps via QR codes or deep links.
