Defi Audit Reports

In the interests of making the Defi space more transparent for investors, we've put together a list of audit reports from different Defi firms.
We've also included a list of the main points from each report, or any impartial comments regarding firms who may have not had an audit report.

Disclaimer: We strongly recommend that investors read through the reports and research each firm independently. Our main points are quotes from each report. A new audit report may have been carried out since we last updated the table, therefore the points may not reflect the present state of security.
