The "SOFR" of DeFi: On-Chain Fixed Income Layer on Mantle
Description:
DOOR Protocol is the first decentralized interest rate derivative platform on Mantle that establishes a standardized "Risk-Free Rate" (DOR) for DeFi. We solve the yield volatility problem by aggregating Mantle’s powerful yields (mETH + RWA) and splitting them into two structured products:
🛡️ Senior Tranche (DOOR-FIX): A "DeFi Savings Account" offering stable, fixed APY (e.g., 5.5%) secured by a first-loss capital buffer. Ideal for institutions and conservative savers.
⚔️ Junior Tranche (DOOR-BOOST): A "Leveraged Yield Engine" that absorbs volatility risk in exchange for 3x+ leveraged returns and ecosystem rewards. Ideal for yield farmers.
Why Mantle?
DOOR leverages Mantle's low gas fees (~0.06 Gwei) to enable daily compounding and rebalancing—a mechanism mathematically impossible on Ethereum L1 due to costs. By integrating Ondo USDY (RWA) and mETH (Double Yield), we bridge the gap between TradFi stability and DeFi profitability.
Key Features:
DOR (Decentralized Offered Rate): A composable benchmark rate (mETH + SOFR + Aave).
Waterfall Distribution: Smart contract logic that strictly prioritizes Senior fixed payouts before Junior leverage.
Epoch System: Weekly rounds to batch liquidity and prevent just-in-time attacks.
DOOR isn't just a yield optimizer; we are building the Interest Rate Layer to unlock the next trillion dollars of institutional capital on Mantle.
DOOR Protocol is a sophisticated dual-tranche vault system deployed on Mantle Network that provides: Senior Vault (sDOOR): Fixed-rate returns (5-8% APY) with priority claim on yields Junior Vault (jDOOR): Leveraged returns (15-30% APY) with first-loss protection for seniors Waterfall Distribution: Automated yield allocation following strict priority ordering Dynamic Safety Module: Real-time risk management with configurable thresholds Oracle-Based Rates: Decentralized rate calculation from multiple sources Key Innovation DOOR Protocol implements a risk-tranching mechanism that allows investors to choose their risk/return profile while maintaining capital efficiency through a unified yield strategy. Junior capital acts as a buffer to protect senior investors, while receiving amplified returns in exchange.
