Just bought a 1,20,000 INR plane ticket from Delhi 🇮🇳 to Toronto 🇨🇦 with my own money!
Feels good.
Wouldn't be possible without web3!
I also have a layover in London, UK.
Will reach Canada on the 12th of May ✌️

We won the Blockhack hackathon 🥳
For which I wrote the ERC721A-gasless smart contract.
It was organized by Bitcoin Bay and they invited us to "The BitAngles Investor Brunch Pitch at AIBC Conference in Toronto"
If you want to fast-track your learning, join a hackathon!

launched their Adidas Originals: Capsule Collection (~0.4 ETH floor now) for which they airdropped all the NFTs.
I found two MISTAKES in their smart contract.

If someone dies, their family can still withdraw their funds from their bank account, but in web3 those funds can never be recovered, unless someone else have their private keys.
Thoughts?

I graduated from the senior track of
@LearnWeb3DAO
Learned a lot of cool concepts such as flash loans, smart contract attacks, upgradeable smart contracts, MEV and gasless transactions.
The best track so far!!
Thanks to the LW3 team!

Someone approached me with their smart contract in which $13k USD worth of BNB is locked.
The smart contract doesn't have any withdraw function and there's no other way to withdraw those funds!
They are locked FOREVER!!!
Idk how devs forget to make the WITHDRAW function!

I was importing my ETH wallet to another device by entering its private key.
By mistake, I entered it incorrectly and submitted it.
Apparently, it was someone else's private key and I got access to their wallet!
Though, they didn't have any crypto in it.

Healthcare system is so bad in Canada. I had to wait 7 hours in emergency with 103 fever and severe pain (it was burst appendix) while I was shivering.
Fortunately, the surgery went well and I’m recovering. Sad, I won’t be able to make it to ETHDenver.
I got really sick today, can’t even stand straight, sit or lay down because of extreme pain in stomach and fever.
This made me realize the value of health and family:
- Health: Be grateful for your good health. I’m in a position where I would do anything to get back to

As a doxxed freelance developer working in web3, I feel like sharing my pictures.
And as I shop for Canada, this might be a good time to share some.
Which one's better?

Alchemy University is soo good!!
You even have interactive playgrounds!!!
It has coding challenges that you pass in order to continue with the course, which really ensures that you understand the topics.

Fun fact: In Solidity, you will get a compilation error if you write a function that has more than 16 local variables declared in it. Because the stack cannot work with data beyond the top 16 elements.

One thing I would recommend everyone to do is to solve at least 1 Leetcode question every day.
Even if you are not preparing for interviews.
Just do it.
It improves your problem solving ability which improves you as a developer.

How to never get rug pulled in NFTs:
Only invest in NFT projects which have:
1. Great founders + team.
2. Active community.
3. Utility.
4. A good vision.

It was a startup incubated by Polygon.

Only 1, that's all! This is what I love about web3.

Why NFTs are not just JPEGs?
The same reason why a $100 note is not just paper.
Everything gets its value when people believe it's valuable.

In Solidity versions >= 0.8.0.
Each time you run a loop, underflow/overflow conditions are checked when incrementing loop variables.
Using "unchecked" keyword to increment loop variables can save you a significant amount of gas.

A huge shoutout to
@mudgen
for helping me to write the gasless ERC721A contract (meta transactions).
He is one of the smartest people I know and a very down-to-earth guy.
Give him a follow and you will learn a lot of things!

Thanks to
@LearnWeb3DAO
, today I made this lottery game on
@0xPolygon
Mumbai network.
It's using
@chainlink
VRF for random winner selection and also using
@graphprotocol
to get the events from our smart contract in real-time.
Go gamble your MATIC 😂:

Well in that case you need to have some money to hire software engineers.
I am sorry to break your hearts but this is the truth.
You can definitely make a product with no code but to make a customised and great product you need to know how to code(or hire engineers)

Why the f*ck relatives have to interfere with what I'm doing with my life?
They just know only a few career options and think that no other option is better than that and you should only do that.
They don't even know about opportunities that exist in today's world, ex: web3

Solidity Tip 💡
Use the "constant" keyword on the state variables that don't need to be changed and save gas in the functions which use those variables.
