YieldProp (Tokenise

YieldProp (Tokenise) democratizes real estate investment by allowing property owners to tokenize assets into fractional ERC-1400 security tokens. Investors can buy fractional shares using USDC, lowering the barrier to entry. The core innovation is a Chainlink Commercial Real Estate (CRE) workflow that fetches live rental market data from external APIs (RentCast), uses OpenAI to generate fair rental pricing recommendations, and writes those recommendations on-chain. This ensures that the property's valuation and the resulting yield distributions are always transparent, automated, and backed by real-world data data. The entire ecosystem is deployed and validated on a Tenderly Virtual TestNet with real-time state synchronization.

Smart Contracts: Solidity (Hardhat) for core logic, including an ERC-1400 PropertyToken, PriceManager, YieldDistributor, and a RecommendationConsumer that implements the Chainlink IReceiver interface. Chainlink CRE: We built a custom CRE workflow (
cre-workflow/yieldprop-workflow/main.ts) utilizing HTTP/Confidential HTTP for external data (RentCast API + OpenAI), DON consensus aggregation, and the EVMClient for on-chain reserve health checks and writing AI pricing recommendations back to the PriceManager via a Keystone Forwarder. Infrastructure: Deployed to Sepolia and fully simulated/tested on a Tenderly Virtual TestNet (Sepolia fork) for zero-friction staging and deep observability. Frontend: Next.js dashboard using Wagmi/Viem for real-time blockchain interactions, allowing users to invest USDC and property managers to trigger yield distributions.
