I owe you so much Patrick. Thank you for introducing me to the beautiful world of Blockchain that I've come to love so much.

Huge thanks to you Patrick Collins! This FULL course on Smart Contract Audits, Security, and DeFi is exactly what I've been searching for. Been wanting to dive deeper into this space for a while, and your clear explanations and comprehensive approach feel like the perfect roadmap. Seriously, the timing couldn't be better with you dropping this now. You're filling a massive gap in the learning resources out there, and I can't wait to get started. Looking forward to following along and putting your lessons into practice. Keep up the fantastic work, and thanks again for sharing your knowledge with the community!

Currently on the 8:40hr mark, and want to say that I found a high severity issue that was missed! (And writted a PoC for it of course) Feeling encouraged by that :D Also got 29 findings hehe I've also found a job as a trainee blockchain developer thanks to the knowledge I gained here, so thanks again!

[@eeeeeeeeebatitupalkata6011]

A huge bug is the fact that in the Puppy Raffle contract, no winner can be picked if someone has refunded. This is because the prize is calculated from the players length which is filled with active players and refunded players (address(0)). Basically it means that if there are 5 players with 1 ETH entrance fee (5 ETH prize pool) and someone refunds, the contract balance is 4 ETH but the prize pool is still the array length which is 5, 4 active players and 1 address(0), that means that the contract balance is less than the prize pool which always reverts leading to a DoS attack of high severity.

Patrick, I saw your previous course with Foundry, it was excellent and of high quality, and now this course is even better. I know that you spend a lot of time and energy on all of this, and my question is, why do you publish it for free? Is there a specific purpose behind this work? I hope one day I can do these things like you

[@PatrickAlphaC]

We ask “what does web3 need?” Everyday at Cyfrin. The answer right now, is “better security information, unbridled by fees so that everyone can level up security” So we do what we think web3 needs, and then we figure out how to make money from it later. What’s more important, is getting the knowledge out there.

Hey Patrick I figured you skipped a vulnerability issue in the PasswordStore exercise. Since the set password could be called by anyone it means the getPassword function is going to return the latest password which could be one set by anyone and not the original password stored by the owner.

Hi Patrick, I watched your foundry course and i undrestand completely and understand solidity and I read solidity document easily and I am familiar with full blockchain concepts and I also understand blockchain protocols such as uniswap V2 and V3. The question I have is, should I work more on developing smart contracts or go into security and start learning and working on smart contracts for security?

Depends - what do you want to do? If security-> do security stuff! If build -> build stuff! If you’re not sure, pick one and then if you decide you don’t like it go to the other!
