🌍 The Problem

Fitness apps have a retention problem. Most people quit within 30 days because there's no real cost to stopping and no tangible reward for continuing. Traditional social features (likes, streaks) aren't enough — they're forgettable.

Daily Habit Hub solves this with skin-in-the-game accountability: your consistency is recorded on-chain and rewarded with tokens you actually own.

🔺 Avalanche Integration

Why Avalanche?

• Sub-second finality — check-in transactions confirm instantly
• Low fees — admin wallet gas costs are negligible (< $0.001 per tx)
• EVM-compatible — full Solidity + wagmi/viem tooling support
• Growing ecosystem — strong DeFi + gaming + health track communities

Smart Contracts (Avalanche C-Chain Mainnet)

Contract	Address	Description
HabitRegistry	0xAb9d332EDeEAB63fc84B72dB7B48Ff81962A6597	Core check-in registry, rate-limited to 1/wallet/UTC day
HabitToken ($HABIT)	0xf392A21a7230a103271ecb88028aDE17B470A267	ERC-20 reward token, 21M cap

Architecture

User checks in
     │
     ▼
Supabase (streak + workout record)
     │
     ▼
POST /api/web3/record-habit  ← server-side admin wallet
     │
     ▼
HabitRegistry.adminRecordHabitForUser(wallet, type, metadataUri)
     │
     ├── mints 10 $HABIT → user wallet
     └── at 7/30/100 check-ins → AchievementNFT.mintAchievement()

Gasless design: Only the admin server wallet pays gas. Users never need AVAX. This removes the #1 barrier to Web3 adoption for fitness users.

Minting Flow

1. User completes a check-in in the app
2. App calls POST /api/web3/record-habit with the user's wallet address
3. Admin wallet calls adminRecordHabitForUser on HabitRegistry
4. Contract mints 10 $HABIT tokens and triggers NFT at milestone counts
5. User sees a toast: "$HABIT tokens minted to your wallet ✨"

🪙 Tokenomics — $HABIT

Parameter	Value
Token Name	HABIT
Token Symbol	$HABIT
Standard	ERC-20 on Avalanche C-Chain
Total Supply Cap	21,000,000 $HABIT
Distribution	100% via usage rewards (no pre-mine, no VC allocation)
Emission Rate	10 $HABIT per verified daily check-in
Minter	HabitRegistry contract only
Utility	Future: in-app purchases, coach payments, governance, staking rewards

Emission Schedule (Projections)

At 21M cap and 10 tokens/check-in:

• 2,100,000 check-ins to reach full supply
• At 100 daily active users doing 1 check-in/day: ~57 years to cap
• At 10,000 DAU: ~0.6 years to cap → triggers scarcity, demand for existing tokens

Why This Model Works

• No inflation risk — hard cap enforced at contract level
• No pre-mine — team earns tokens the same way users do
• Usage-backed value — tokens are only created by real human activity
• Community-first — largest holders are the most consistent users
