Sismo Connect is a crypto-native single sign-on method (SSO) for applications—whether on web2 or web3. Integration is simple with just a few lines of code: import the front-end package or React button for data requests, and verify proofs using the Sismo Connect Solidity library in your smart contract OR server package in your back end. Once integrated, applications can request private and granular data, while users can authenticate and selectively disclose their personal data with the power of zero-knowledge proofs (ZKPs).
After successful proof generation, users are redirected back to the Sismo Connect app with their generated proofs. The app's front end can either call a smart contract or its back end to verify the proofs.
The proof is received by the smart contract OR the backend and verified.
Certain logic is then executed if proofs are valid, successfully ending the Sismo Connect flow.
