1 ▸ Why QReward needs to exist
In 2001, the McDonald’s Monopoly Scam cost $24 million in fake prizes due to backend fraud and opaque systems. Even today, users scan scratch cards and QR codes in blind faith — hoping the company “actually” rewards winners.
Consumers need proof. Companies need public trust. QReward delivers both.
2 ▸ How QReward works — step-by-step
What a user or company sees
What happens behind the scenes
Scan QR Code
User visits a local shop, scans a QR from their bill
→ qr-scanner detects the code → Campaign ID is fetched.
Claim Verification
User clicks “Claim Reward”
→ Smart contract verifies if the QR is active and unclaimed → Sends ETH if valid.
ETH Received + Proof
User sees reward instantly + Etherscan link
→ Tx hash + amount is shown on frontend → On-chain proof of reward.
Company Dashboard
Brand logs in via Google / MetaMask
→ Launches a new campaign → ETH is locked on-chain → QR codes are generated.
Reputation Score (Coming Soon)
User builds claim history → Verified wallet activity → Future campaigns gated by score.
