# Other Maple pools Active loans Methodology

## 1. Overview

Active loans measures the total value of outstanding principal lent out to borrowers from Other Maple pools. The portion of user deposits that actively generate interest for depositors is tracked, reflecting the lending activity of these pools. Only real-world commercial loans are included in this metric, while internal capital allocations, strategy deployments, and undrawn loans are excluded.

## 2. Data sources

- **Blockchain events**: `LoanFunded` events from `Pool` contracts, `ClaimedFundsDistributed` events from `LoanManager` contracts, and `FundsDistributed` events from `FTLoanManager` contracts, alongside daily loan principal and borrower metadata state records, covering Ethereum
- **External data**: Asset metadata for decimal normalization

## 3. Step-by-step calculation

### Component A: Drawn loan verification

- **Purpose**: Identify loans that have been active and drawn down by borrowers.
- **Logic**: Loans are verified as drawn if they are associated with a `LoanFunded` event from V1 `Pool` contracts, a `ClaimedFundsDistributed` event from V2 `LoanManager` contracts, or a `FundsDistributed` event from V2 `FTLoanManager` contracts. Alternatively, loans are verified if the `date_funded` field in the loan metadata is populated with a value greater than zero.
- **Key fields**: `loan` (loan address), `loan_` (loan address), `date_funded` (funding timestamp)

### Component B: Principal extraction and filtering

- **Purpose**: Extract outstanding principal and filter out non-commercial loans.
- **Logic**: Daily outstanding principal balances are extracted from loan state records. Loans with a principal balance of zero or null are excluded. To isolate real-world commercial loans, allocations to strategy deployments, DeFi positions, AMM liquidity, and intercompany transfers are filtered out by excluding loans associated with known internal borrower addresses (`0x2570faf7c8a0da87d3f123b35cc722ec3fcc3e08`, `0xb32dd55d4ff63e39c304b00e069fbaefe885f0fb`, and `0xa1ca50c6adf6579e26f70b0f9c16b062f5f618ca`).
- **Key fields**: `principal` (outstanding principal), `borrower` (borrower address), `account_address` (loan contract address)

### Component C: Product mapping and decimal normalization

- **Purpose**: Map loans to Other Maple pools and normalize values.
- **Logic**: Lender addresses (representing loan managers) are mapped to their respective products. Loans managed by loan managers not associated with Maple Finance syrupUSDC, Maple Finance syrupUSDT, Maple Finance syrupUSDG, or Maple Institutional are categorized under Other Maple pools. Raw principal amounts are normalized by asset decimal precision, where WETH loans are divided by 18 decimals and all other assets (such as USDC and USDT) are divided by 6 decimals.
- **Key fields**: `lender` (lender address), `token_address` (underlying asset address), `principal_raw` (unscaled principal)

Active loans

Lending

Pool delegates create a pool and attract funding, from which they receive a portion of the establishment fee and the interest accrued. Liquidity providers add liquidity to the pool and receive a portion of the interest (supply-side fees).

Maple is a non-custodial lending protocol built on Ethereum offering undercollateralized loans for institutional borrowers. Maple was founded by Sid Powell and Joe Flanagan and launched in 2021.

MPL token holders govern and own the protocol. They currently take a cut of the establishment fee (revenue). Maple’s investors include Framework Ventures, One Block Capital, Stani Kulechov etc.
