      I love @compoundfinance as a concept and as a product. But this code https://etherscan.io/address/0x3d9819210a31b4961b30ef54be2aed79b9c9cd3b#code … controlling soon $100M scares the shit out of me. Many thousand lines of code, assembly use, literally 6 open "todo's".

      Replying to @koeppelmann @compoundfinance

      Martin, Gnosis contracts also use many lines of code, inline assembly and, occasionally, comments. I've love to walk you through our code, as we've done with our auditors: @trailofbits and @Certora1. Excited to discuss and answer any questions you have.

      While I'm waiting for my afternoon coffee to kick in, I've got a few thoughts about security audits mainly in the area of expectations and results.

      I put the final report for our Compound v2 review on our publications repo just now. The final report has one extra week compared to the one linked on Reddit. https://github.com/trailofbits/publications/blob/master/reviews/compound-2.pdf …

      Similar the thread from @jessysaurusrex, I would strongly caution that many people misread the outcome of security reviews. They are primarily intended for the product's own engineering team and half the purpose is education.
