Binance ID - Wallet SDK


Welcome to the Wallet Software Development Kit (SDK) documentation. This SDK is designed to empower third-party Decentralized Applications (DApps) by enabling seamless integration with the Binance DeFi Wallet. By leveraging the SDK, developers can enhance their DApp's user experience and provide seamless access to the advanced features of the Binance DeFi Wallet.

The Binance DeFi Wallet is built on the latest multi-party computation (MPC) cryptographic standard, providing unmatched security. With this technique, private keys remain secure and confidential, as each party only has access to its own key fragment.

In addition to exceptional security, the Binance DeFi Wallet offers a comprehensive suite of advanced features, including Binance ID, biometric authentication, Wallet Connect support, and SoulBound Tokens (SBT).

The SDK supports standard functionality such as connecting and signing transactions. It also continuously expands its capabilities, offering unique features like fund transfers from the user's Binance account to a Web3 wallet when using a DApp, with more features to come in the future.

Note: Currently, the Wallet SDK is only provided to close ecosystem partners. For more information, please contact our business team.
