Additional fee information on a reserve

These exist separately from interest accrual fees, and are specifically for the program owner and frontend host. The fees are paid out as a percentage of liquidity token amounts during repayments and liquidations.

Fields

borrow_fee_wad: u64

Fee assessed on BorrowObligationLiquidity, expressed as a Wad. Must be between 0 and 10^18, such that 10^18 = 1. A few examples for clarity: 1% = 10_000_000_000_000_000 0.01% (1 basis point) = 100_000_000_000_000 0.00001% (Aave borrow fee) = 100_000_000_000

flash_loan_fee_wad: u64

Fee for flash loan, expressed as a Wad.

host_fee_percentage: u8

Amount of fee going to host account, if provided in liquidate and repay
