Cipher Shastra is a Security Playground to help people learn Blockchain Security, Smart Contract Exploitation, Cryptography by playing CTF like Challenges
Seems like you guys are up for a new challenge?
The Factory needs to make a special color, but seems like it is not possible with the colors available. Can you help?
Let's Mix Some Colors!

The RareSkills Book of Gas Optimization has been published.
With over > 90 pointers and 11k+ words, not including source code, you are almost certainly going to see a trick or two you haven't seen before.
We assume you know the EVM to a certain degree, this is not a beginner tutorial.
As you can see from the photo, the post is so long we ran into size issues with our hosting platform! So we will publish the next section shortly and link to it.
This was a team effort. Authors: @Jesserc_@AmadiMichaels@supernovahs444.
Stay tuned, we are ramping up the scale of content production and building systems to publish quality articles and books even faster.
Soon enough, RareSkills will be your one-stop shop for all the advanced tutorials you could ever wish for. We have big plans with more announcements to come!
Enjoy! https://t.co/PCEmneUUvg

Summary: yeah it's possible, but there are a lot of tradeoffs.
Thanks @abdelstark for suggesting this topic!

Cairo is an awesome language for developing programs with provable execution, and the core component of StarkNet!
I've compiled some vulnerability classes that you might find in Cairo(/StarkNet) programs!
