Sismo Connect is single sign-on method for applications enabling aggregated data requests to users thanks to privacy. Once integrated, applications can request private, granular data from users, while users can authenticate and selectively reveal their data thanks to zero-knowledge proofs (ZKPs).

The Sismo Connect Server is a backend package built on top of the Hydra-S2 Verifier to easily verify proofs from your users off-chain.

Here is the link to the full documentation of the package: Sismo Connect Server package.
