In crypto the auditing process is somewhat more sophisticated. They scan the contract for similarity to known scams and analyze it for possible backdoors. They also do due diligence on the promoter of the contract ("fully doxxed").

In reality of course all this work could have been replaced by def is_fraud():return True

And the accuracy would probably increase. Crypto fraud has the beautiful property that the people being defrauded actively defend the fraudsters. Moreover, in a lot of cases it isn't technically fraud since the contract is upfront about what it does but at the same time it is very exploitative but that doesn't matter to crypto people
