Yield-Collateralized RWA Purchasing on Mantle Network
💡 Concept
Your staking yield automatically buys Real World Assets. Principal stays 100% safe.
🔄 How It Works
1. Deposit mETH into Accrue Vault
2. Earn staking yield (auto-tracked)
3. Select target RWA (real estate, bonds, etc.)
4. Harvest - yield converts to fractionalized RWA tokens
5. Withdraw principal anytime - RWAs are yours to keep
🏠 Available RWAs
| Asset | APY | Price/Fraction |
| NYC Real Estate | 4.5% | 0.01 mETH |
| Treasury Bonds | 5.25% | 0.001 mETH |
| Invoice Financing | 8.5% | 0.005 mETH |
| Green Infrastructure | 6.5% | 0.002 mETH |
🛠️ Built With
- Solidity - ERC-4626 + ERC-1155
- Mantle Network - Low gas, mETH native
- Next.js - Modern React frontend
- Wagmi/RainbowKit - Web3 connectivity
✅ Status
- 🟢 Deployed on Mantle Sepolia
- 🟢 35/35 tests passing
- 🟢 Full demo flow working
🎯 Value Proposition
| Traditional | Accrue |
| Yield OR real assets | Yield AND real assets |
| Principal at risk | Principal protected |
| High minimum investment | Start with any amount |
| Complex process | One-click harvest |
Bottom line: DeFi meets RWA. No trade-offs. Just accumulation.
