So, let's keep it real.

I nailed my first solo high and crushed at least two solo audits every month.

But hey, no shame in admitting my smart contract security skills can level up big time.

Here are my next three steps for becoming an advanced researcher. 🧵
I'm diving into the previous Secureum races, but with a twist!

Gonna convert Solidity contracts to IR/Yul using

$forge inspect <contract> ir

Then solve the races using Yul output.

Let's see if I can conquer 'em!
Gotta admit, my "Ethereum specs" knowledge needs work.

Thanks to @Sabnock66, I'm hitting up the Ethereum execution specs repo to master it all!

github.com/ethereum/execu…

Time to level up my Ethereum game!
I always wanted to try Paradigm CTF, but never felt ready.

Today, I feel ready.
Finally, I'm taking the plunge!
Focusing on EVM challenges only.

As mentioned in another thread, I've learned not to overcommit. I think these three will keep me busy for the next few months.

And of course, I will keep you posted with my progress 🫡
That's a wrap!

When I started the @Web3SecurityDAO I didn't expect it to explode to that level.

I thought I would chat with 20-30 like-minded folks about stuff that intrigues me.

Right now, it has over 1700 members.

Today, @Web3SecurityDAO merges into @opensensepw

Here's why: 🧵
I made the community to help and to get helped.

Unfortunately, I don't have the time and mental power to give back, so I felt that I'm letting down the community I've built.

@mis4nthr0pic has done an excellent job at what I wanted to do initially, so the move is natural.
Frankly, @Web3SecurityDAO and @opensensepw have a common mission:

To create a supportive environment for people to learn web3 security in public.

So, even if I DID have the time, it would still be the better choice to take the same decision.

🔥 Get a FREE medium severity finding on ANY @code4rena or @sherlockdefi

This vulnerability stems from the fact that using block.timestamp for deadline could result in loss of funds for the user 🧵 Image
If you want a long explanation why that can happen, check my article about it.

blog.bytes032.xyz/p/why-you-shou…

Otherwise, you might check that even Uniswap set a default deadline, if the user doesn't pick one. 👇
On their FE, they use is 60 minutes for main net and 5 minutes for L2's. Image

Here's the 5-step framework I used to learn Solidity 6 months ago: 🧵
# 1 A 32 hours course to get you started

This introductory course has become synonymous with the question, "How do I learn Solidity?"

Virtually everyone dipping their toes in the Solidity pool starts here.

No further introduction needed.
# 2 Learn by doing with CryptoZombies

Once you've acquired a foundational understanding, it's time to roll up your sleeves and delve into self-guided learning.

6 months ago, I took a deep dive into security with a simple question:

“How do I get better at this?”

6 months later, I have a messy notepad full of notes, an entirely new way of seeing the space.

Here are 5 profound mistakes everyone should avoid if they want to save time 🧵
Mistake #1: Overstudying

I erroneously believed that the **ONLY** path to proficiency was through devouring countless roadmaps and religiously studying Secureum.
However, I now understand that the key is balance: about 30% theoretical study and 70% practical application.

In this field, practice is primarily what will lead to a consistent and positive outcome

Did you know you can use console.log to debug a deployed contract on a fork with Foundry? 🫢

Introducing vm.etch as your debugging solution in three simple steps 🧵

Let's assume we want to debug the deposit function of BlurPool. Image
1. Download the source code as a ZIP file from Etherscan.

etherscan.io/address/0x02ab… Image
2. Customize BlurPool's deposit function as desired

From now on, I want BlurPool's deposit to console.log bruh every time that a new deposit is made. Image

🔥 Get a FREE medium severity finding on ANY @code4rena or @sherlockdefi contest using Chainlink on L2!

This vulnerability stems from the potential for the sequencer to go offline, which could result in outdated and stale oracle data. 🧵 Image
Optimistic rollup protocols transfer all execution from the Layer 1 (L1) Ethereum chain to a Layer 2 (L2) chain, perform the execution on the L2 chain, and then return the results to the L1 chain.
These protocols employ a sequencer to process and aggregate L2 transactions by consolidating multiple transactions into a single one.
