After almost a year of intensive Solana auditing, examining codebases written without Anchor requires a distinct approach compared to Anchor-based programs. Anchor consistently handles validation automatically behind the scenes, which developers might overlook during the coding

Recently in private audits, I started writing coded PoCs when the test suite is setup already (I don't mind spending from 4 to 8 hours to make the setup work on my device). This saves everyone time. However, I do it only for issues that are not obvious and a bit complex or

Auditing any Solana program is at least 30-40% Anchor auditing without reporting to Anchor's (excluding Vanilla programs).

A great business engagement is to not take things personally. 99%, people don't know you, and you don't know them. Actions based on speculation don't bring you forward (put aside trading). That's not easy to do, but if you do, you keep the long-term road up. Remember that

Got an offer from a big firm to join as SR, but I couldn't continue the process. They don't provide part-time option. Sad, but can't trade off freedom/flexibility

It pains me to see code4rena and Sherlock having no active web3 security contests. These two platforms have given so much value to the whole ecosystem. My wish is for their comeback as once upon a time, competition between contest platforms is badly needed for all of us here🙏
