Real-world assets (RWAs) are poised for significant growth within the blockchain ecosystem, especially in DeFi, by introducing new mechanisms for collateralisation, derivatives, stable assets, and yield opportunities. Our proposal focuses on Plain Finance, a protocol designed for the secure, open market engagement in the custodial management of real-estate assets, facilitating the decentralised minting, issuance, and exchange of tokenised real-estate shares. We aim to demonstrate how Arbitrum will be the primary blockchain for asset origination, with Uniswap V4 underpinning the exchange framework.

Real-estate represents the largest global asset class, and its tokenisation promises to unlock liquidity while maintaining stability. The current lack of a protocol for verifying off-chain data and processes risks fragmenting custodians and issuers, sidelining under-capitalised participants due to increased trust requirements and potential for data manipulation. Traditional transparency methods, such as third-party audits and attestations, suffer from bias, bribery, and infrequent updates, leading to vulnerabilities such as stablecoin de-pegging and yield source suspicions.

Our solution encompasses the technical application of our research into verifiable transparency, economic incentive structures, and governance mechanisms. We introduce a zkOracle Framework for creating market-specific zkOracles, starting with Australia, enabling custodians to verify data related to asset custody, valuation, and dividends. This includes zkProofs for reserves, identity, legal structure, etc., all verified on the Arbitrum One blockchain. This technology assures investor capital access after asset custody verification, with blockchain event emissions for public auditing. A dApp will allow investors to view verified data and engage with property governance, crowdfunding, and income withdrawal features. Each property will be paired with a stablecoin like USDC in a custom Uniswap V4 Pool for exchange.
