Borrowing
Overview
Flux Finance is a trustless overcollaterized lending protocol. A borrower must provide collateral worth more than the debt to guarantee an incentive to repay it.
Each asset has an associated collateral ratio: the share of its value that can be borrowed. Assets with zero collateral ratio can't be used as collateral.
Borrowers mint fTokens — just like lenders — and deposit them as collateral. Your supplied assets still earn interest (i.e. the supply rate) while you're using them as collateral, potentially offsetting your borrowing costs (i.e. the borrow rate).
The borrow rate for an asset fluctuates based on its utilization (i.e. the percentage of the asset's pool that has been borrowed). The borrow rate increases as utilization increases, balancing supply and demand for a given asset. The borrow rate increases sharply once utilization surpasses a threshold ('kink'), incentivizing borrowers to repay some of the debt to maintain enough liquidity for lenders.
Borrowers should monitor their positions to ensure that their LTV stays at a healthy level. If the account liquidity (i.e. the aggregate collateral factor of its assets) becomes negative, the borrower's account will become liquidable and might incur a small liquidation fee. Refer to Liquidations for details.
