This repo contains a set of contracts to facilitate on-chain Loans between Maple Finance Pools and institutional borrowers. These contracts contain logic to:

1. Deploy new Loans.
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.

Contracts in this repo inherit and import code from:

• maple-labs/erc20
• maple-labs/erc20-helper
• maple-labs/maple-proxy-factory

Contracts inherit and import code in the following ways:

• MapleLoan and MapleLoanFeeManager use IERC20 and ERC20Helper for token interactions.
• MapleLoan inherits MapleProxiedInternals for proxy logic.
• MapleLoanFactory inherits MapleProxyFactory for proxy deployment and management.

Versions of dependencies can be checked with git submodule status.
