2. Perform Loan funding.
3. Draw down funds.
4. Manage collateral.
5. Calculate payment amounts and schedules (can handle amortized and interest-only payment structures).
6. Perform repossessions of collateral and remaining funds in a defaulted Loan.
7. Claim interest and principal from Loans.
8. Perform refinancing operations when a lender and borrower agree to new terms.
9. Upgrade Loan logic using upgradeability patterns.
