Description
🔐 Behave2Have – “Your Behavior Is Your Access”
Behave2Have is a privacy-preserving onchain reputation engine that converts your MetaMask Card spending into real-world rewards — without exposing personal data.
We use ZK-KYC, behavioral scoring, and tier-based loyalty unlocks to let users build reputation and claim USDC rewards, merchant perks, and exclusive access — just by how they behave onchain.
🧠 Real Problems Solved:
Users hate repeating invasive KYC across platforms.
Loyalty cards are fragmented and non-transferable.
There's no private, fair, and cross-chain reputation system.
Rewards are not tied to behavior — only to total spending.
🎯 How It Works:
ZK-KYC Verification → prove you're human without exposing age/income.
Simulate Spending → earn loyalty points.
Update Reputation Score → based on real behavior.
Unlock Tiers (Bronze → Platinum) → based on score.
Claim USDC Rewards (via Circle CCTP) → from loyalty vault.
Unlock Real Perks → Starbucks, Netflix discounts based on tier.
Privacy Toggle → you decide what’s shared. Tier score updates accordingly.
View All Logs → every action transparently logged.
