Key Takeaway
A PropTech company built a multi-condition smart contract escrow system for commercial real estate. Five conditions confirmed by authorized wallets: title clear, financing confirmed, inspection passed, appraisal at value, dispute window. Average closing time: 23 days → 47 hours. Zero disputes in first 6 months. Development cost: $92,000.
The Problem
Standard commercial real estate closing involves: title search (7–14 days), financing confirmation (5–10 days), inspection sign-off (3–7 days), appraisal (5–10 days), documentary review (3–5 days). Much of this is sequential when it could be parallel, and each step requires manual coordination. Total closing timeline: 21–45 days.
Solution Architecture
Multi-condition smart contract escrow. Buyer deposits USDC into escrow at contract signing. Five conditions, each confirmed by an authorized wallet: (1) Title clear: title company's wallet, (2) Financing confirmed: lender's wallet, (3) Inspection passed: inspector's wallet, (4) Appraisal at or above purchase price: appraiser's wallet, (5) 24-hour dispute window: no dispute submitted.
