3SWallet.js is a Javascript library that connects your dapps to millions of 3S Wallet users' assets and NFTs. It's a wrapper library of WalletConnect to communicate securely between 3S Wallet and Dapps. The connection is established when the counter-party approves the connection request initiated by one peer displaying a QR Code or deep link with a standard WalletConnect URI.
