Scratch Cards is a Web3 lottery platform letting brands give away real NFT and cash prizes via physical cards
Campaigns are set up via an admin dashboard: smart contracts deployed, NFTs minted, codes generated, and prizes tracked on-chain.
For users, the flow is simple: scan a card, see results instantly, and know if they’ve won an NFT or cash - no wallets, gas, or crypto needed.

What We Delivered
Bringing Web3 to scratch cards hid crypto complexity behind a simple scan, letting users play, win, and claim on-chain rewards.
Scan-and-reveal flow that hides wallets, gas and chain interaction
Campaign setup that deploys contracts, mints NFTs and generates card QR codes
On-chain scan validation, so a brand can show which card won what
Prizes claimed as NFT assets or redeemed in USDC stablecoin
Bridging offline scratch cards with on-chain rewards
The client wanted real lotteries with NFT and cash prizes, but most users had never used crypto or Web3 wallets. Managing thousands of cards manually while preventing fraud and keeping prizes transparent was impossible
Building a Web3 engine behind a simple scratch card
We built a platform where admins configure campaigns while the system deploys smart contracts, mints NFTs, generates QR codes, validates scans, and users scan the card, reveal the result, and claim a blockchain prize.
Web3 Ownership & NFT Assets
Scratch Cards utilizes Web3 technologies and NFTs to deliver a transparent, player-owned experience. Players claim verifiable digital assets and redeem prizes directly in stable coin (USDC).
Players have full rights to sell, trade, or collect their NFT assets.
Asset rarity (1 in 2K, 1 in 100K) is transparent and verifiable.
Prizes are redeemable as a stable, real-world value (USDC).
Technology Stack
What Scratch Cards runs on: the scan flow a player sees, the smart contracts that hold the prize logic, and the admin side that sets a campaign up.
Player app
Stack: Scan-and-reveal mobile flow
Core Benefit: A player scans a card and sees the result at once, without a wallet, gas or any crypto knowledge.
Smart contracts
Stack: On-chain prize logic
Core Benefit: Prize logic lives in smart contracts, and every scan is validated on-chain, so a brand can show which card won what.
NFT and payouts
Stack: NFT minting, USDC redemption
Core Benefit: Campaign setup mints the NFT assets, and a winner keeps the asset or redeems the prize in USDC.
Card codes
Stack: QR generation and on-chain checks
Core Benefit: Every printed card carries a generated code that is validated before a prize is shown.
Admin
Stack: Campaign dashboard and API
Core Benefit: Admins set a campaign up: contracts deployed, NFTs minted, card codes generated, prizes tracked.
Retail
Stack: Authorized app with integrated scanner
Core Benefit: Instant ticket sales and reward processing in store, with customer verification by digital signature.
Design & Experience
The UI/UX design is inspired by the aesthetics of digital rewards - vibrant, high-contrast, and focused on the win.
We designed the interface for effortless interaction
We used clear layouts, high-contrast result screens, and intuitive scan flows to make claiming on-chain rewards feel as seamless as a traditional lottery.
Retail App
Authorized retail application for instant ticket sales and digital reward processing. Use the integrated scanner to process ticket data and verify customer information via digital signature.
Outcome
Scratch Cards turned traditional promotions into a verifiable Web3 lottery system, where every scan can unlock an NFT or cash prize.
The MVP was delivered in just 3 months, combining smart-contract powered prize logic, NFT minting, QR card generation and a simple mobile flow that works for non-crypto users.
Today the platform gives brands a secure way to run large-scale campaigns with on-chain transparency, reduced fraud risk and a memorable scratch-card experience that users actually enjoy.

The full scope above is 10-17 weeks in our model. A first version that is mobile only lands in the same 10-17 weeks. This project shipped its MVP in 3 months.
From the same model that runs our public cost calculator: kultrix.com/cost-calculator. Module hours are added up and multiplied by 1.25, because the glue between modules, the end-to-end testing and the release cycle belong to no single module. A third-party integration like the chain layer here is 70-180 hours on its own.
