• Programmable loan terms: fixed-rate, fixed-term, LTV ratios, interest accrual, and repayment schedules
• Automated interest and repayment logic
• Default / liquidation handling via TAURUS unilateral timelock and penalty mechanisms
• Real-time proof-of-reserves and loan health visibility

Success Criteria

• End-to-end flow: deposit BTC → issue credit token → borrow/use credit → repay → unlock collateral
• Loan health and collateral are verifiable via HAT/RIP proofs
• Defaults are handled gracefully with lender recourse and unilateral exit guarantees
• Clean institutional-ready UI with dashboards and transparency tools
