Overview

Sismo Connect enables applications to request data from users. Applications receive ZK Proofs they can verify onchain or offchain.
Integrate Sismo Connect in 3 steps:
  • Create a Sismo Connect app in the Sismo Factory
  • Frontend: Use our React button or client library to request ZK proofs from users (like you would request a signature with Wallet Connect)
  • Smart Contracts/Backend: Use our Solidity/TypeScript library to verify those ZK proofs (like you would verify a signature with ethers/viem/ecrecover)
