Users of the protocol face two risks, the risk that Notional gets hacked and the risk that borrowers on the platform become insolvent. Notional takes security extremely seriously and has never been hacked. The protocol has been audited by industry leaders including Open Zeppelin, Certora, ABDK, and Code Arena. Notional’s liquidation infrastructure makes sure that borrowers do not become insolvent, and if they do, the protocol shields users from any losses with its reserve funds.

Lenders and borrowers get fixed interest rates on Notional which can’t and won’t change over the course of the maturity. While stable rates do exist on other platforms (usually at a premium) they are not fixed and often do change with certain market conditions.

You can close out your loan and withdraw your funds at any time prior to maturity without penalty. By doing so, you would be closing out the remaining portion of your loan at the prevailing market rate - this could be at a higher or lower rate than what you started with.
