How It Works — Scratch
Klarhaus is Chisino's prize-linked savings engine. The scratch card is the first application — but the engine is product-agnostic.
Coming soon
Scratch is currently in development. The mechanics described below are final — the product has not yet launched. Games (Roulette, Wheel, Slots) are live now.
To participate, you need pUSD (PlayUSD). Deposit USDM and receive pUSD at a 1:1 ratio.
Your pUSD is backed 1:1 by stablecoins in the ReceiptVault. You can redeem back to stablecoins at any time.
Each scratch card costs 3 pUSD.
Each play mints an ERC-721 NFT ticket to your wallet. Playing also earns 0.4 $HOUSE per play.
Reveal your card to see the outcome. Results are determined by VRF (Verifiable Random Function) — completely fair and verifiable on-chain.
16 reward tiers from 0x to 3333x — View all tiers
If You Win
Rewards are paid instantly from the Prize Pool. Earn up to 10,000 pUSD (3333x your 3 pUSD entry).
If You Don't Win Big
Your NFT ticket accrues yield over time. Once it reaches 3 pUSD (your full entry cost), burn the NFT and redeem in full. Entry value is designed to be recoverable through yield — time is the cost, not money.
The Ticket Claim Vault (TCV) deploys capital to yield strategies. 50% of TCV yield goes to ticket restoration — growing each ticket from 1.50 pUSD toward 3.00 pUSD. Recovery depends on yield rates from external protocols and is not guaranteed. Recovery timelines vary based on yield rates and market conditions. The $0.25 protocol fee per play is not recoverable.
How Your 3 pUSD Is Allocated
Every play splits across three destinations.
