Integrating WalletConnect and the Wallet SDK provides **institutional-grade control** while maintaining **interoperability** across thousands of dapps. Custodians can enforce granular permissions, from domain and contract verification to policy-based transaction controls, all while retaining full custody of client assets. ## Why WalletConnect? WalletConnect provides the **largest and most established gateway to DeFi**, designed for scale and institutional reliability. ### \$400 Billion Total Network Volume Total Network Volume (TNV) is the total value of all transactions routed through the WalletConnect network in a given time (annually, in this case). So this represents how much money actually flows through the WalletConnect. WalletConnect has long been the quiet backbone of Web3 and not "just a QR code". It’s the invisible glue that connects users, dApps, and wallets, and now the scale finally shows it. ### Fully Chain-Agnostic WalletConnect supports 300+ EVM chains, Bitcoin, Solana, and 70+ other networks. Any network with a CAIP-25 namespace is supported. ### Available on 70,000+ dApps WalletConnect is available on 70,000+ dApps, making it the most widely used wallet connection protocol in the world. ### Available on 500+ wallets WalletConnect is available on 500+ wallets, making it the most robust and user-friendly.
