      It was more than just security experts who understood this about @HegicOptions. It was obvious that further work was needed to non-experts too. “It's OK we have no tests because the auditors will catch all the bugs” said no one ever https://twitter.com/BlockEnthusiast/status/1254132916675907584 …https://twitter.com/hitchcott/status/1253982497446166528 …

      We know there are roadblocks to interpreting our results by non-experts. For example, we purposefully avoid subjective opinions in our reports, preferring objective facts to maintain our integrity and independence.https://twitter.com/HeidyKhlaaf/status/1254121886902083584 …

      These criticism lack any realism in how auditing works. Working in Safety, where government auditors are also involved, independent auditors have their hand tied and can seldomly make "human readable" recommendations. We provide objective technical observations. That's it.

      Further, it's possible for clients to simply ignore what we document in reports. @trailofbits does not have any authority over our clients, we simply provide them advice. https://twitter.com/HeidyKhlaaf/status/1254122500407152640 …https://twitter.com/spencecoin/status/1254116602720608258 …

      ^^^^ THIS Security audits are an audit of the security. They are purely objective. They provided ALL the information and unfortunately can't control what happens after that information is given. Dan and trailofbits performed exactly as they should have.

      How will we improve after this incident? 1st, we will no longer work with @HegicOptions. Their behavior has been deeply irresponsible. They ignored our advice and recklessly put user funds at risk. This hurts the entire DeFi community.

      2nd, we will keep services from @trailofbits accessible for those with lower or limited financial resources. Security assistance is essential for smaller projects, and we'll continue to help those that need it with shorter project sizes.

      3rd, we'll add structure to our summary reports to help readers better evaluate the current state and maturity of the project while remaining objective. It's unfortunate so few people look beyond our reports so we'll provide stats and info about the code in them.

      hi dan, could you add a standardized outgoing confidence to your audits? I have read many of your audtis and trail of bits has a very good standards for the 1 & 2. /https://twitter.com/scott_lew_is/status/1254089620037480450?s=20 …

      scott lewis 🌾 @scott_lew_is
      for every custodial contract audit i would like to see: 1. engineer hours spent on audit. 2. bug distribution: (crit/high/medium/low/info) 3. auditors outgoing confidence level on the safety of contract going forward: (inadequate/adequate/acceptable/excellent) we need all 3.

      second, does trail of bits ever "unpublish" public audits? I have been unable to locate the Compound V1 audit. was it ever public? if we are trying to determine how much value an audit adds to the safety of a project, the less selection bias in the data set, the better.

      Thanks for the Qs. 1) We need to stick to objectivity. No subjective opinions about "confidence" (varies by person, impossible to measure, etc). Instead, we'll make it easier to understand the current level of risk and recommended actions going forward.

      2) We don't publish all of our reports, particularly ones that involve corporate, internal, or cloud security, which were areas of focus for our first Compound review. This IT infrastructure is not available outside the company, therefore the review of it is not either.
