I genuinely believe you only need two resources to grasp Solidity:

1. Solidity v0.8.0 playlist by Smart Contract Programmer
2. Ethernaut by OpenZeppelin

With consistent effort, you can get there in just 1–1.5 month.

you move your btc to a cold wallet to stay safe, you wake up one day and boom you are broke again

"594 bitcoin worth about $38M, was swept from ~500 wallets on Friday in an attack traced to a flaw in how Coldcard hardware wallets generated their keys"

@0xSilvermist Absolutely deserved 🚀

[Alexander Gadzhalov @agadzhalov]

@0xSilvermist @asen_sec there's absolutely nothing that beats consistency, congrats

[Alexander Gadzhalov @agadzhalov]

@MartinMarchev @thedaofund Congrats ser, the space need more people like you 🚀

There's a Bulgarian proverb literally translated as "Hunger is stronger than electricity" and that story proves it.

Around last year this month of April, I was under a lot of financial pressure. Family had a lot of debt, no money, wifi and phone lines cut off, nobody could talk to each-other, no food, I used to eat potatoes my brother made with some garlic, and no hope for any better future, last attempts at creating something valuable in the world failed despite being very close. Failure was all there was.

When humans face immense pressure, I believe they turn into a robotic state, they stop processing emotions temporarily and the need to have a purpose or to think something through before doing it is gone so is your self-awareness, you just turn into this thing that needs to survive at least one last time. I went to libraries and worked there I didn’t expect much I just did whatever I had to do when libraries closed I used to park outside the library in the parking so I can still access the library’s wifi.

April was a difficult month but then that’s when May came.

@MartinMarchev congrats ser, i hope money won't change you

@PatrickAlphaC there are people that still put their pk in plaintext? damn

[Alexander Gadzhalov @agadzhalov]

@lyubomirlb stay tuned brother

Just today AI companies raised $1,600,000,000

Starcloud - $170M
Qodo - $70M
Mistral AI - $830M
Rebellions - $400M
ScaleOps - $130M

and the day is not over yet.

[Alexander Gadzhalov @agadzhalov]

@yotov721 I agree 100%. When it comes to smart contracts in my opinion developers must understand every single line of code they'd written/auto-completed. AI generates way too much code and if you go in that direction with smart contracts the chance of ending on @RektHQ is very high.

[Alexander Gadzhalov @agadzhalov]

@lyubomirlb Best products are built during the bear

[Alexander Gadzhalov @agadzhalov]

BTC is going to $25,000

Another day in my Rust journey learned about:
- How to dockerize Rust projects
- Advanced error handling
- Generics
- Traits
Next topic is "macros".

[Alexander Gadzhalov @agadzhalov]

Today I’ve finished this beginner Rust playlist.

Covers the fundamentals, then wraps with a mini blockchain project: scan a chain, fetch wallet balances, and inspect transactions.

It's worth watching if you are new to Rust.

[Alexander Gadzhalov @agadzhalov]

Another day in my Rust journey - learned about references, borrowing (“&”), imm/mutable references and slice types.

Definitely I will need hands on practice with these to get more confident and understand them better.

Not a very easy chapter from the Rust book.

[Alexander Gadzhalov @agadzhalov]

Another great year at @LimeChainHQ.
Had the opportunity to work with amazing professionals and gained an insane amount of knowledge.

We built a chain, explorer, bridge, faucet, and a gamification platform.

Looking forward to 2026 as we continue delivering high-end products.

[Alexander Gadzhalov @agadzhalov]

Now you may wonder what is Ownership.

In Rust when a variable goes out of scope, the compiler automatically calls a special function called “drop”, which frees the memory.

[Alexander Gadzhalov @agadzhalov]

Today started learning about ownership in Rust.
This is the unique feature that distinguishes Rust from other languages.

In Java you have Garbage Collection which manages memory
In C++ you have to manually allocate the memory

Rust uses third approach which is called "ownership"

[Alexander Gadzhalov @agadzhalov]

Finished Chapter 3 from the Rust book today.

Learned about arrays, vectors, functions, returns-s, if-s, three types of loops (loop, for, while) and loop labels.

I will be honest - this chapter was pretty boring.

[Alexander Gadzhalov @agadzhalov]

From experience I know that just by reading a book you won’t understand everything in a programming language. You need to combine theory and practice.

Rustlings are great exercises that I am solving while reading the Rust Programming Language
