Cornerstone: Tokenizing Debt on Pre-Construction Real Estate

Cornerstone

Created At

ETHOnline 2025

Project Description

Cornerstone is a decentralized platform that allows global investors to participate in real estate development projects before construction begins, earning fixed, risk-adjusted yields. Unlike other tokenization models that focus on equity, ownership, or project cashflows (which are high-risk and dependent on volatile market conditions), Cornerstone instead tokenizes developer debt obligations. This makes investments low-risk and bound by project proformas, giving investors predictable, enforceable returns. By combining stablecoins, smart contracts, and legally enforceable SPV structures, the platform opens access to an asset class traditionally reserved for banks and large institutions. Investors benefit from transparency, liquidity, and secure returns, while developers gain faster, more flexible funding.

Core Features

  • Milestone-Based Funding: A 6-phase lifecycle (Fundraising to Sales) that algorithmically enforces the project's draw schedule.
  • On-Chain Escrow & Accountability: Capital is secured by the protocol. Developers must submit on-chain proof of work to unlock the next tranche of funding, eliminating the risk of mismanaged funds.
  • Dynamic Interest Accrual: Phase-specific APRs (funded by the developer) algorithmically reward investors who commit capital to earlier, riskier stages.
  • Fair & Liquid Markets: Integrated transfer hooks ensure that all accounting for interest and revenue remains fair, enabling project tokens to be traded freely on a DEX.

How it's Made

The Lifecycle in Brief The entire protocol is governed by a 6-phase smart contract: Phase 0: Fundraising: The initial capital raise with defined min/max targets. Phase 1-4: Development: (Design, Permitting, Demolition, Construction). The developer completes work, submits proof, and unlocks the pre-set funding cap for that milestone. Phase 5: Revenue & Sales: The developer deposits sales revenue, and the contract executes the automated principal-then-profit waterfall.

We use a share based token that accrues yields as they are paid out. Tokens are made liquid over a Uniswap liquidity pool on Sepolia.

  • A Vincent ability is used to auto-balance the pool as interest is accrued. -Avail was used to perform deposits, withdrawals and other actions from any chain.
  • Envio was used to index and populate a dashboard of rich data about the project.
