event details


zkBob UI is developed as a client side application which generates zkproofs on a user's machine. This is ideal from a security and privacy standpoint, however it can introduce some obstacles for application developers. To simplify zkBob interactivity and reduce friction for users and application developers, we have released the zkBob API and cloud wallet into beta.

With the API, developers do not need to use a client SDK to manage crytpographic keys, client application state and other complexities. Users do not need to secure keys entirely on their own or wait for cryptographic proof generation. The hosted version of the zkBob REST API and cloud wallet greatly expands the possibilities for interaction. For the hackathon, we want you to explore new use cases for private transactions using the zkBob API and BOB stablecoin.


  • Build on Polygon
  • Use BOB custodial API (zkBob cloud) for private transfers

Use Case Ideas:

  • Donation platform where donors maintain anonymity
  • Fundraising platform with internal KYC while maintaining public privacy
