WalletConnect v2.0
Get started. Integrate web3 wallet connection and messaging into your wallet or dapp with WalletConnect's SDK suite for mobile and web developers.
What is WalletConnect?
WalletConnect is an open-source protocol that allows you to connect your mobile wallet to different decentralized applications and other wallets. Historically this has been done through a QR code, which establishes a secure end-to-end encrypted connection between the two devices. This allows you to interact with dapps and sign transactions securely from your mobile wallet.
