# AF1.0 Interest Rate Model

Persuant to AIP-25's resolution, some LYF positions following migration batches were force-closed, and all lending assets were migrated to AF2.0 lending pools. You can claim ibTokens corresponding to their assets on AF2.0.
Thus, some parts of this page is only a referenced information before the migration.

We employ a triple-slope interest rate model to determine the borrowing interest rate. See details below:
