The problem UK Property Oracle with Chainlink solves
🏠 RealEstate Oracle – Tokenizing UK Property with Chainlink
🚀 One-Liner
We tokenize UK property into digital shares using blockchain + Chainlink oracles — making real estate investment faster, cheaper, and accessible to everyone.
📌 Problem
Traditional property investment is:
- 💸 Expensive → requires large upfront capital.
- 🐌 Slow → months of paperwork, legal checks, middlemen.
- 🚪 Limited → exclusive to wealthy buyers and institutions.
💡 Solution
RealEstate Oracle enables fractional property ownership:
- 🏘️ Property owners unlock liquidity by converting assets into digital tokens.
- 👥 Investors can buy shares of real UK properties starting from £100.
- 🔗 Chainlink Functions ensure trusted property/legal data directly on-chain.
🌍 Market Opportunity
The UK real estate market is worth £1.6 trillion.
Capturing just 0.1% through tokenization = £1.6 billion opportunity.
⚙️ How It Works
- Property owner lists property.
- We tokenize into 100–1,000 digital shares.
- Investors purchase tokens.
- Chainlink oracles verify property & legal data.
- Investors earn returns from rent & appreciation.
🎯 Why Us
- 🥇 First-mover advantage in the UK: while most projects are still pilots, we are building a live MVP with real properties.
- 🔗 Chainlink-powered: verifiable data ensures trust + automation.
- 📑 Compliance-first: designed for UK regulations, bridging blockchain and real estate.
🔑 Current Focus (2025)
- Tokenizing 1–3 pilot properties by October 2025.
- Showcasing MVP at London Blockchain Conference.
- Building a network of early investors & property owners.
📩 Call to Action
We are looking for:
- 🏠 Property owners/developers → to join our pilot program.
- 💰 Investors → to participate in fractional ownership opportunities.
- 🤝 Partners → legal, fintech, and blockchain collaborators.
Challenges I ran into
🐞 Challenges I Ran Into
While building this project, I ran into a few key challenges:
Chainlink Functions JavaScript Execution Error
During the integration of Chainlink Functions to fetch mock property data using inline JavaScript, I encountered a runtime error:
"return value not an ArrayBuffer or Uint8Array".
This happened while trying to encode property data using ethers.utils.defaultAbiCoder.
How I addressed it:
I restructured the JavaScript source to properly return ABI-encoded values and ensured the data types matched the expected output in Solidity. I also handled the decoding process on-chain carefully to avoid mismatches.
UI Log Errors in Chainlink Explorer
When submitting test requests, the Chainlink Explorer sometimes displayed unexplained UI log errors, even when the response reached the contract.
Solution: After confirming that on-chain data (via properties[id]) was correctly updated and all emitted events worked, I documented this as a non-blocking UI issue.
Time Constraints
As the submission deadline approached, I had to prioritize clarity and reliability. Despite minor errors, I ensured that all critical functions worked and documented known limitations transparently.
