WalletConnect SDK (Wallet SDK)

The WalletConnect SDK is the developer toolkit that enables crypto wallet developers to integrate their wallets with the WalletConnect Network, providing access to over 80,000 decentralized applications through a single, standardized implementation. It is the foundational connectivity layer of the WalletConnect Protocol, trusted by custodians, self-custody wallets, mobile wallet apps, and hardware wallet manufacturers.
