We’ve just wrapped up our first public testnet event, and here’s everything we learned from building, scaling, and proving it under real-world conditions.

Deep dive: Hyligotchi, your testnet companion

Deep dive: Hyligotchi, your testnet companion

A Hyligotchi follows you around in the Hyli testnet world. This entirely ZK-proven little creature is hungry for oranges, so you’ll need to play a lot of testnet games to keep it happy… and alive!

Deep dive: Orange trail, rolling with rollups

Deep dive: Orange trail, rolling with rollups

Want to explore the world of the Hyli testnet? You’ll have to face the daunting Orange Trail, a multiplayer exploration game where every step is a bet on whether you’ll make it back to your base with the oxygen you need.

Deep dive: the proof-of-work Hyli Chat

Deep dive: the proof-of-work Hyli Chat

The Hyli testnet features a fully onchain and ZK-powered chat. It leverages client-side proving and bypasses pipelined proving as a built-in spam minimization system.

Deep dive: eZKasino, fully-proven blackjack

Deep dive: eZKasino, fully-proven blackjack

The Hyli testnet includes, of course, an eZKasino: a fully proven game of blackjack, complete with a Windows XP interface, just because we can.

Deep dive: the Hyli wallet abstracts your identity
