1. High-Level System Interaction

• Post Collateral: Underwriters deposit at least three (3) equal quantities of unexpired UWTs as collateral.
• Borrow RUSD: The facility mints and lends up to 20% LTV in new RUSD against posted collateral.
• On-Chain Accounting: RUSD liabilities and Total RUSD Outstanding metrics increase to reflect the loan.

2. Collateral, LTV & Payments

• Collateral Units: UWT collateral must be unexpired and posted in equal quantities per selected pool.
• Monthly Payment: 1.5% of the original collateral amount is automatically deducted from collateral each month to service the loan.
• Health Threshold: If collateral value falls below 70% of the original collateral amount, the position is liquidated.
• Liquidation Proceeds: Collateral is sold to repay principal and fees; any surplus (minus transaction costs) becomes claimable by the borrower.

3. Rebalancing & Flexibility

• Collateral Swaps: At any time, borrowers may swap a collateral asset for an equivalent amount/value of a different UWT or RUSD without closing the loan.
• Top-Ups: Borrowers may add RUSD to improve LTV and avoid liquidation.
• Prepayment: Loans can be reduced or closed at any time by repaying RUSD; collateral is released accordingly.

4. Contract Design

• Vault Mappings: Tracks borrower → {posted UWT lots, original collateral amount, current value, accrued payments, LTV, health factor}.
• Mint/Burn Hooks: Loan issuance mints RUSD to the borrower and updates liability metrics; repayment burns RUSD and releases collateral.
• Automated Oracle Inputs: UWT valuations sourced on-chain to compute LTV and liquidation triggers.

5. Risk Safeguards & Governance

• Fully Collateralized: Max 20% LTV with automated liquidation at 70% collateral health.
• Transparency: Reserves, liabilities, collateral, and outstanding RUSD are visible on-chain in real time.
• Compliance: AML/KYC for borrowers; withdrawals to verified destinations only.
• Permissive Action Links (Patent-Possible): Strong-link approvals for loan issuance/parameter updates; weak-link guards for automatic protective actions under adverse conditions.

6. Participant Roles

• Borrowers (Underwriters): Post UWT collateral, borrow RUSD for trading or operations, manage LTV via swaps and top-ups.
• Facility Reserve: Issues/absorbs RUSD via mint/burn with full collateralization; no rehypothecation.
• Automated Oracles/Governance: Provide valuations, enforce thresholds, and oversee parameters and compliance.

7. Institutional Relevance

The facility delivers auditable, programmatic credit that turns underwriter positions into working capital without compromising reserve integrity. Loans are short-term, adjustable, and fully collateralized—aligning with institutional requirements for transparency, risk controls, and compliance.

Underwriters may use the facility in several ways to optimize their capital strategies:

• Expand Insurance Capacity: Borrow against UWT collateral to write additional insurance, increasing coverage sold and potential profits.
• Improve Operational Cashflow: Unlock liquidity from UWT collateral to support day-to-day business needs while maintaining exposure to insurance pools.
• Tax Deferment Strategies: Structure borrowing and repayments to defer recognition of taxable events, creating flexibility in financial planning.

In addition, the credit facility naturally incentivizes underwriters to lock up their UWTs, reducing redemption pressure and increasing deposits in the RUSD reserve. This deepens the pool of assets on which interest is earned, reinforcing the strength and stability of the broader ecosystem.
