MarketingTech
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.

Bringing Web3 to scratch cards hid crypto complexity behind a simple scan, letting users play, win, and claim on-chain rewards.
99%
of card scans instantly resolve in under three seconds, giving “scratch-and-win” feedback that keeps users engaged.
95%
increase in engagement versus traditional promo-code campaigns when rewards are delivered via Web3 scratch-card lotteries.
89%
of prizes are backed by smart contracts, verifiable on-chain, giving brands, users full transparency over every cash payout.
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).

FAQ
Got Questions?
Our approach is to design an MVP that can go live quickly, but on top of an architecture that is ready to scale. The same team can then continue with you to add features, improve performance and support growth.
Yes. We often step into running products to stabilise architecture, redesign UX, improve performance or add new modules—without stopping your current business operations.
We begin with a short discovery phase: clarifying goals, success metrics, scope and constraints. Based on this, we propose a roadmap, team composition and timeline so everyone is aligned before development starts.
We agree on a clear communication channel (Slack, Teams or similar) and run regular check-ins. You receive progress updates, demos and short written summaries so stakeholders always know what has been done and what comes next.
Just reach out with a short description of your idea or product. We’ll schedule a call, estimate the scope and suggest a collaboration model that fits your timeline and budget.
That’s fine. We can help you shape the product through workshops, discovery sprints and UX prototypes, then translate that into a clear backlog and technical plan for the development team.
On the front end we mostly use React, Next.js and React Native; on the back end—Node.js and microservice architectures deployed with Docker and cloud providers like AWS. For specific cases we also work with Web3 stacks and AI integrations.
We focus on end-to-end digital products: mobile apps, web platforms, SaaS tools and Web3 solutions. Our team covers UI/UX design, front-end, back-end and long-term product evolution.
