Pine's fee structure has been purposely designed to make the protocol sustainable and scalable.
The Pine Protocol fees are governed by the PineDAO. This values are:
The Protocol charges an interest rate spread between the rate the borrower pays and the lender receives on every Transaction happens via the Protocol. The fee is determined algorithmically depending on the lender rate and pricing parameters of the Protocol.
Based on current fee parameters set by the Pine Protocol as of September 2022
In the event of early repayment (i.e. repaying all or any amount of the outstanding loan before the end of the term), the borrower is liable for any interest accrued up till that point of time. On the portion that is repaid early before the end of the term, the borrower is liable for a portion of the interest that is supposed to have accrued if the repayment is done at the end of the term. The portion is calculated using the Early Repayment Interest Discount %.
After a loan has expired, the interest rate chargable would be equivalent to the original interest rate times the Late Repayment Interest Multiplier.
In the event of liquidation, the lender is charged a percentage, equivalent to the Liquidation Fee %, of the value of the NFT Collateral above the value of outstanding loan. Lenders would have to pay this fee when they withdraw the NFT collateral from the smart contract of the loan in default.
The charge is waived in the case of liquidation at a loss when the value of the outstanding loan exceeds the value of the NFT Collateral.
With Pine Listing (see Pine Listing for more information), borrowers can list their NFT for sale even when they are being used as collateral for loans. The protocol charges a Pine Listing Sales fee on the amount the NFT is sold for.
In the previous version (Pine Protocol V2), the fee structure is a simple flat fee of 0.01 ETH and 0.35% of the total loan amount paid by the borrower. Some of the current lending pools might still be on this fee structure but will be all be migrated to V3 in the near future.
