😸😸Follow Patrick!😸😸

For any of you who are having trouble trying to run a particular test, forge test -m is deprecated, use forge test --match-test (or forge test --mt) instead

Aside from all the unnecessary scripts for chainlink stuff which makes the course 100x more difficult for beginners, this is an absolute gem, thanks Patrick for all the work !

[zachcomeau]

This is a very good course. The way it is set up allows you to get some victories along the way to encourage you to keep pushing forward until completion.

Patrick is a very good instructor and a wealth of knowledge and best practices.

[Komk]

This is everything I've been looking for since diving into Web3! I'm extremely grateful and looking forward to jump in the trenches with the rest of the Web3 Security Researchers. This is gold and Patrick is a God Send

[MachinebrainsMcd]

Patrick is a very competent instructor - explained all concepts well and clearly, the course has helped provide an intermediate starting point for understanding programming in Solidity, Foundry Book, Chainlink Api-Docs, Automation-Subscription and AlchemyApi- which certainly will prove useful gaining a sound Solidity Knowledge Foundation. Pace - excellent, content - superb, good use of theory and very hands-on, thank you very much! Exactly what I wanted albeit puzzling at times rewatching the videos and coding persistently really helps. looking forward to lesson 10 and beyond...Thanks Again🚀

[migueldlr]

i have 0 knowledge in coding, i studied medicine, for 5 years brah. Thought this was gonna be impossible to achive at my age(34) but im doing quite good. Hope a can get there this year.
Thanks a lot for all the lessons, really really high value on this videos. Good luck in everything man

[rashmikadissanayake]

I am new to web3 and just finished the first video. Very addictive. Thank you much Patrick for this awesome lecture series. If there's someone who is still learning and like to team up just reply me here. Thanks.

[intellectance]

Bro this is way underrated
For me this three videos are acting as a course that I am doing to get job and internships and hopefully will soon grab one if able to complete 👌💯the whole three videos

If you made it this far congrats! :>
You are now obliged to get some Ice Cream like what Patrick said 🍦🍦🍦

[amank]

These three videos are the best things that have happened to me in the last 3 months 🥳

[ayanmohammed]

Hello everyone, just finished the first video and it is a great starting point. Patrick has done a phenomenal job in these videos!!
If there's anyone who'd wanna team up to complete this series then please do reply!!

[sayandcode]

Just finished the vid! Thanks Patrick!!! The only comprehensive Solidity course on the internet

[captpython]

Woow .. This is the course what I was looking for . Thank you again @patric for this wonderful resource .. I bet this course is a Gold standard in Web3 learning

[d.finance]

No ice cream! If you need a break, go hit the gym!@!@
Love the course Patrick. 3rd time through. Really sinking in, especially the programmatic deployment and fuzz tests. Thank you.

[splendorwhite]

Thanks for sharing such a amazing course! It gives me a door to a brand new world!

[x-Issa]

Thank you so much Patrick 🙏🏾. Just finished this massive lesson. Only way is up from here 🚀

[jizoschoutsen]

I just coded the two test functions we had to write ourselves. It was pretty tough, took me like 20 minutes, but I think they work how they're supposed to (they do look a bit different than your solutions on the repo though)! It really helped making all the other code make more sense, I was just copying everything you did without understanding it fully but now it makes more sense to me. I think it's a good idea to give more little assignments like that every once in a while.

[beccalangdon]

So many hours of hanging out with Patrick!
