Tutorials and Examples

See the Getting Started page for an initial intro, but if you prefer learning from interactive code, check out the example app below.

ZApp Test client

A fully function Zapp client with executable examples.

  • Run the test client here.
  • Source is available in the Zupass repo here.

Live Apps

These apps all use the Z-API in production. More live apps coming soon. They’re launching at Devcon now…

Frogcrypto

A game of collecting cryptographic frogs. Frogcrypto is re-launching at Devcon 7 SEA with new features to discover. More details here after the conferene.

Meerkat

Meerkat is a Q&A app for live audience engagement. With Meerkat, attendees of an event or conference can submit questions, upvote their favorites, share reactions, and collect session artifacts as PODs. At an event, each talk will display a QR code, making it easy to join the Q&A by verifying your access through your privacy-preserving Zupass access ticket.

Frog Lab

Derive novel substances from your frogs. The lab uses the Z-API to select frogs, and generate novel substances saved back to Zupass as PODs.

FrogJuice

Squeeze your frogs and get rewards on-chain! FrogJuice is the first demonstration of on-chain verification of GPC proofs, using frog PODs issued by FrogCrypto.
