Audit ResultsSummary

Function borrow_liquidity

The function is called to borrow liquidity out of the reserve. This function only handles the removal of the coins from the reserve and not the accounting against the individual user. That is handled in lending_market.

The function deducts a borrow fee in cTokens, which is added to the special fee store of the current reserve. The fee is paid immediately and is added to the total debt, which is returned.

There is a check that the total amount borrowed in this reserve does not exceed a configuration limit and that the remaining amount in the reserve is above the hardcoded minimum.
