Overview
zkPoker is a poker app that lets you play hands of Texas Hold'em directly against other players, straight from your Cardano wallet, with no central poker site holding the money1. It is aimed at poker players who want to skip rake fees and middlemen, and at curious newcomers who want to see what a wallet-to-wallet card game feels like. Each deal is verified by a math check that proves the cards were dealt fairly without revealing them, a method called a zero-knowledge proof.
zkPoker is built on Cardano by the Cardano After Dark team and runs on Hydra, a fast lane connected to the main Cardano network so card actions can feel instant2. The published build is a practice version (running on Cardano's preprod test network, with no real money at stake) shown at the Cardano Summit, and the project's token sale is paused ahead of a full launch1.
Key Features
- Play wallet-to-wallet with no house in the middle. Players sit at a peer-to-peer table and settle bets through Cardano contracts, so there is no central poker site that can freeze accounts or change the rules1.
- Hands you can verify, not just trust. Every deal is checked by a math proof that confirms the cards were dealt fairly without exposing anyone's hole cards. The team frames this as an academic-style trustless protocol1.
- Built on Hydra for real-time play. The game runs inside a Hydra fast lane connected to Cardano, so card actions feel instant rather than waiting for each block to be added to the main chain3.
- Custom DRED messaging layer. The team built a dedicated low-latency communication layer called DRED to carry game messages between players without a central server4.
- Funded by Cardano Catalyst with open code. The project has delivered four Cardano Catalyst grants across Funds 7, 8, and 13. Catalyst is Cardano's community grant program. zkPoker develops in the open through its public GitHub organization56.
- Genesis Player NFT for early access. Anyone interested can sign up for a free NFT that registers them ahead of future releases. The team's separate token sale is paused1.
What to Expect
Visiting zkpoker.io is a marketing-first experience: the homepage explains the concept, links a recorded gameplay demo on YouTube, and points to the Cardano After Dark blog for longer reads on the underlying tech. There is no live poker room on the main Cardano network yet.
To actually try the game, you open the practice app at app.zkpoker.io and connect a Cardano wallet that supports test networks. The site lists Eternl, Yoroi, Typhon, GeroWallet, NuFi, Lace, Begin, and VESPR. Because the build runs on Cardano's preprod test network (the practice version of the chain, with no real ADA at risk), no deposit is required. Curious players can also register for the Genesis Player NFT, delegate ADA to the team's DRED stake pool to support ongoing development, or follow updates on the team's Discord and YouTube channels.
zkPoker is best understood as an early, transparent attempt at a serverless poker app on Cardano rather than a finished product.
