RevitaHub - Build Our Community

RevitaHub is a platform that lets communities collectively own local real estate and infrastructure through fractional tokenized ownership — starting at $12.50 per token — governed by an on-chain DAO and fully automated by Chainlink CRE.
The Problem
Community infrastructure fails for three reasons: no single investor can carry the full cost, there is no mechanism for small-denomination community ownership, and there is no trustless way to protect investors if a raise falls short. Traditional crowdfunding solves the first problem but ignores the other two.
The First Project: Carroll County Speedway
Carroll County, Georgia has 132,000 residents and zero active dirt tracks. Every racing fan dollar leaves the county every weekend. RevitaHub gives the community a path to collectively build and own the venue they want — starting at $12.50.
How It Works

1. Community nominates a project via the RevitaHub wishlist
   • The property is tokenized as ERC-1155 on Base L2 with 4 price tiers: Phase 1: County residents · $12.50 · 1.5× voting weight
   • Phase 2: State investors · $18.75 · 1.25× voting weight
   • Phase 3: National · $28.13 · 1.0× voting weight
   • Phase 4: International · $37.50 · 0.75× voting weight
2. County residents get first access at lowest price and highest governance weight
3. Chainlink CRE monitors community engagement every 6 hours via the RevitaHub API and automatically advances to the next phase when 75% engagement is reached
4. Token holders vote on all development decisions through an on-chain DAO
5. If the 12-month funding deadline passes without hitting the target, Chainlink CRE automatically triggers a 100% refund plus 3% APR interest — no human required
6. Once the venue is built, Chainlink CRE distributes quarterly dividends to all token holders proportional to their stake
   What Makes It Different
   RevitaHub puts the community first in every design decision — lowest token price, highest vote weight, earliest access. The platform earns 5% of revenue; 95% goes back to the people who funded it. If it fails, they get their money back with interest. Chainlink CRE is what makes all of this trustless and automated.

Frontend Next.js dApp hosted at buildourcommunity.co. Residents sign up, nominate projects, buy tokens, and vote — all from a single interface designed for non-crypto-native users.
Blockchain Layer Base L2 (Coinbase) — chosen for sub-cent gas fees and Coinbase consumer onboarding, which lets residents buy tokens with a debit card. No prior crypto experience needed.
Smart contracts:

• RevitaToken.sol — ERC-1155 multi-phase token with tiered pricing and vote weights
• RevitaTreasury.sol — 2-of-3 Gnosis Safe multi-sig holds all investor funds
• RevitaGovernor.sol — OpenZeppelin DAO governance for all project decisions
• RevitaDividend.sol — Quarterly dividend distribution logic
  Chainlink CRE — Three Workflows

1. workflow-phase-advance.ts Cron trigger (every 6 hours) → HTTP GET to RevitaHub engagement API → if score ≥ 75%, writes phase advancement to RevitaToken contract on Base L2.
2. workflow-refund-guard.ts Cron trigger (daily midnight) → EVM Read of deadline and funding state → if deadline passed and target not met, writes refund trigger to RevitaTreasury.
3. workflow-dividend-distributor.ts HTTP trigger (quarterly, from treasury) → HTTP GET token holder list and balances → calculates pro-rata amounts → writes distribution to RevitaDividend contract.
   All three workflows integrate the blockchain with an external API (the RevitaHub engagement and holder registry API), satisfying the CRE requirement to connect a blockchain with an external data source.
   Governance OpenZeppelin Governor with AI pre-screening of proposals before votes open. 2-of-3 Gnosis Safe multi-sig treasury — no single actor can move funds.
