Economic Model

Overview

Buoy.Loan's economic model creates a self-sustaining credit loop where validator staking rewards from HYPE continuously service debt obligations while Morpho market dynamics determine liquidity provider returns. The fixed 10% LTV cap ensures protocol solvency, with all risks isolated to liquidity providers rather than borrowers.

This design aligns incentives across stakers, borrowers, and LPs: staking secures the network, borrowing unlocks capital efficiency, and validator yield powers repayment without liquidation exposure.

Key Economic Parameters

Parameter	Value	Description
Max LTV	10%	Borrowing limit against staked HYPE USD value ​
Interest Source	Morpho Vaults	Dynamic rates based on buoyUSD/USDC and buoyUSD/USDh utilization
Repayment Source	Validator Rewards	HYPE staking yield covers interest + principal reduction
Loan Growth	None	Borrowed principal can only be reduced with self-repayments from validator rewards

Revenue and Repayment Flows

Validator rewards from staked HYPE follow a priority waterfall:

1. Interest Payments to Morpho LPs (market-determined rate).

2. Principal Reduction by buying back and burning buoyUSD.

3. Protocol Reserve (excess yield after full repayment).

LP Yield Formula (per Morpho vault): Market Interest = Base Rate + (Utilization × Spread Factor)

LPs earn this rate on supplied USDC/USDh, while validator rewards ensure steady debt service regardless of utilization levels.

LTV and Yield Dynamics

The 10% LTV creates natural safety margins. At typical HyperEVM validator APYs (~2.3%), rewards exceed Morpho borrow rates on stablecoins even during high-utilization spikes.

Morpho utilization directly impacts LP returns but not borrower risk—high utilization raises rates (benefiting LPs), while validator yield provides baseline repayment.

Risk and Incentive Alignment

Participant	Primary Reward	Risk Exposure
Stakers/Borrowers	Self-repaying loans + full HYPE yield	None (no liquidation)
Liquidity Providers	Morpho interest + validator repayment	Market utilization risk

This model ensures capital efficiency without systemic risk, positioning Buoy.Loan as a foundational primitive for HyperEVM yield optimization.
