Our smart contracts for the Platypus Finance integration were audited by Omniscia, the same company that audited Platypus Finance. We worked with Omniscia extensively to identify and resolve security concerns on our smart contracts.
You can read the audit report here.
The contracts for our Trader Joe pools use the same template as those reviewed by Omniscia. The contracts have also been reviewed by peer reviewers familiar with Trader Joe's contracts.
