Hedge real-world risks on-chain
About
The problem it solves In traditional finance, hedging against real-world risks like inflation, currency devaluation, and unforeseen events is often limited to large institutions with access to complex derivatives, structured products, or offshore banking solutions. Retail investors, everyday users, and businesses in high-inflation economies face significant barriers to protecting their wealth. Existing solutions are fragmented, highly regulated, and inaccessible to most people. Web3, on the other hand, has built sophisticated financial instruments, but many are designed for on-chain speculation rather than real-world economic security. DeFi has revolutionized lending, borrowing, and trading, yet there is no unified, flexible protocol that allows individuals to hedge against real-life financial risks in a permissionless, decentralized way. Our ERC-4626-based Risk Hedge Protocol addresses this gap by offering a flexible framework that enables users to create structured hedging instruments for various real-world risks. The first proof of concept focuses on hedging against inflation, specifically the depreciation of the Turkish Lira. By leveraging decentralized finance, users can deposit stable assets and gain exposure to structured products that protect against currency devaluation. This model can be extended to other inflationary currencies like the Argentine Peso, as well as broader risk markets, such as stablecoin de-pegging and weather-based insurance. By making risk hedging accessible, transparent, and decentralized, our protocol empowers users worldwide to safeguard their assets against economic volatility. Unlike centralized financial products, it is censorship-resistant, globally accessible, and eliminates reliance on traditional intermediaries. This is the next step in bringing DeFi closer to real-world use cases—providing financial security, not just speculation. User Interaction and Data Flow # **Data Flow of a Risk Hedge Vault** The **Risk Hedge Vault** enables decentralized hedging against real-world risks (inflation, FX devaluation, weather events, etc.). Users take **both sides of the bet**—either as **Hedgers** (seeking protection) or **Risk Takers** (providing liquidity). Settlement is determined by **oracle data** at maturity. ## **1️⃣ Market Creation & Oracle Setup** - A **Risk Market** is created (e.g., “Turkish Lira inflation > X% in 6 months”). - Parameters are set: - **Asset Pair** (USDT, USDC, ETH) - **Hedge Metric** (Inflation rate, FX rate) - **Maturity Date** - **Oracle Source** (Acurast, Chainlink) - Two **ERC-4626 Vaults** are deployed: - **Hedge Vault** (for hedgers) - **Risk Vault** (for risk takers) ## **2️⃣ Deposits & Position Taking** - **Hedgers** deposit into the **Hedge Vault** to buy protection. - **Risk Takers** deposit into the **Risk Vault** to provide liquidity and earn yield. - Vaults issue **ERC-4626 receipt tokens**. ## **3️⃣ Maturity & Oracle Settlement** - On the **maturity date**, the **oracle fetches real-world data**. - The smart contract compares the fetched data with the **hedge condition**: - ✅ **Condition Met** → **Hedge Vault wins**, paid from Risk Vault. - ❌ **Condition Not Met** → **Risk Vault wins**, funds remain with risk takers. ## **4️⃣ Liquidation & Payout** - The contract **automatically settles payouts**. - Users **withdraw their shares** based on the oracle result. - The vault resets for future hedging rounds. ## **Key Features** ✅ **Non-custodial & trustless** – Funds remain in smart contracts. ✅ **Permissionless access** – Anyone can create or join a hedge. ✅ **Scalable** – Supports **inflation hedging, FX risk, stablecoin de-pegs, weather insurance, etc.** This **ERC-4626 Risk Hedge Protocol** bridges **DeFi & real-world risk management**, offering decentralized protection against economic volatility. 🚀 The project architecture and development process # **🏗️ Architecture & Development Process of the Risk Hedge Protocol** The **Risk Hedge Protocol** is a modular, **ERC-4626-based** framework enabling users to hedge against **real-world risks** like inflation, FX devaluation, and market instability. We deployed across **Sepolia, Hedera Testnet, and U2U Testnet (Nebula)** to test adaptability across different blockchain environments. ## **🔧 Architecture Breakdown** ### **1️⃣ Smart Contract Design** - **ERC-4626 Vaults**: Two vaults per hedge market—**Hedge Vault (protection seekers)** and **Risk Vault (liquidity providers)**. - **Oracle Integration**: Contracts fetch **real-world risk data** via **Acurast TEE oracles** for automatic settlement. - **Liquidation Logic**: At **maturity**, the contract calculates payouts based on **oracle results**. ### **2️⃣ Multi-Network Deployment & Stablecoin Challenges** 💠 **Sepolia (Ethereum Testnet)**: Used **RLUSD (Ripple Labs USD)** as the stablecoin for deposits, ensuring a **real-world test scenario**. 💠 **Hedera Testnet**: Used **mock tokens**, as we didn’t integrate **HTS (Hedera Token Service)** at this stage—**native Hedera token handling is a future upgrade**. 💠 **U2U Testnet (Nebula)**: No suitable stablecoin was available, so we **deployed mock stablecoins** for initial testing. Product Integrations # **🔗 Product Integration Overview** The **Risk Hedge Protocol** integrates real-world financial data with on-chain smart contracts to enable seamless risk hedging. - **Forex API Integration**: We fetch **currency exchange rates & inflation data** from sources like **XE.com**, ensuring accurate real-world pricing. - **Acurast TEE (Trusted Execution Environment)**: The **Acurast network securely retrieves and forwards API data** to our smart contracts, minimizing trust assumptions. - **Multi-Chain Smart Contracts**: - **Hedera** – Deployed with mock stablecoins, pending HTS integration. - **Sepolia (Ethereum Testnet)** – Uses **RLUSD (Ripple Labs USD)** for real asset testing. - **U2U Testnet (Nebula)** – Runs with **mock stablecoins** until a suitable stablecoin is available. This **decentralized architecture** ensures **secure, trustless, and automated risk hedging**, bridging **off-chain financial data with on-chain execution**. 🚀 Key differentiators and uniqueness of the project # **🌍 Uniqueness of the Risk Hedge Protocol** Unlike typical **on-chain degen apps**, this is a **Real-World Asset (RWA) project**, bridging **DeFi with real-world risk hedging**. - **Real-World Data Integration**: We utilize **Forex APIs (e.g., XE.com)** to fetch live financial data, ensuring on-chain hedging is backed by real market conditions. - **TEE-Powered Oracle (Acurast)**: Our **Trusted Execution Environment (TEE)** fetches and verifies **off-chain data** before securely relaying it to smart contracts, eliminating reliance on centralized oracles. - **Multi-Chain Deployment**: Smart contracts on **Hedera, Sepolia, and U2U** ensure interoperability across different blockchain ecosystems. This is more than just another DeFi protocol—it’s a **next-gen risk hedge solution**, integrating **real-world finance with decentralized infrastructure** to provide **trustless, automated risk protection**. 🚀 Trade-offs and shortcuts while building We deployed our own token to act as standin stablecoins for Hedera and u2u network Additional Features We built both the UI and the contracts during this hackathon. Although I have built something similar on non EVM chains (not in solidity). So the architecture is not completely new to us, and also we have acurast before
