Day5/100 of #100daysofsolidity
Today, I learned how virtual and override work in solidity when dealing with functions across contracts.
What I learned:
• virtual allow a function in a parent contract to be overridden
• override is used in replacing parent implementation.
Day4/100 of #100daysOfSolidity
Today, l learned how different contracts can interact with each other seamlessly!
Managed to get my Factory contract talking to my sub-contracts using function calls. It's starting to feel like building a real ecosystem.
Day 2/100 of #100DaysOfSolidity
Today I learned:
✅ The difference between calldata and memory
✅ how to use struct properly
✅ how mapping works
Key insight: what my code basically does is to get different client favourite number and their names.
Challenges: None
#Web3
I am officially starting #100DaysOfSolidity!
MyGoal: Transition from a curious learner to a job-ready Smart Contract Developer.
To I dived into:
✅ State Variables (permanent storage on the EVM!)
✅ Functions
✅ Visibility Keywords (Public vs Private)
Day 12: Binge-watched the updated Blockchain Basics on Cyfrin Updraft before moving to Foundry.
Foundation first, greatness next. 💪

Day off mode.
Didn’t code. Didn’t study. Just rested.
Sometimes doing nothing is doing something — recharging for what’s next.

5. Day 8 ✅
Learning to see past “code that works” and focus on code that’s secure 🛡️

Solidity is fun — not just logic, but creation.
I can’t wait to put this knowledge to work, maintaining real contracts and helping projects scale safely on-chain.
Each line of code is training for that moment.

Day 55 / 100 : Deep dive day.
Reviewed notes & solidified what I’ve been learning lately. Confidently cementing my inner booklet this time
Below is a quick review to remind you too...

Day 53 / 100 — Back on track 🚀
Last update was Sept 1 —working on a rebase vault then. Since then I’ve built a rebase pool + learned a ton.
I paused documenting,but never stopped building.
I’m back,consistent &finishing what I started.

Day 12 of learning #Solidity 💻
Today I dived into ERC20 tokens — the backbone of most crypto assets! 🚀
Learnt how tokens are minted, transferred, approved, and how they power DeFi protocols.
Every line of code = more control over digital money ⚙️💰

Day 7 of #100DaysOfSolidity 🚀
Learned about:
🔹Visibility — public, external, internal, private
🔹immutable — set once at deployment, never changes
🔹payable — lets contracts receive ETH
Connecting more dots daily. Solidity is 🔥@CyfrinUpdraft
#BuildInPublic #Web3 #Solidity
Day 33 of Blockchain Training w/ @CyfrinUpdraft 🚀
🔹 Custom Errors
🔹 Contract Events
🔹 Block.timestamp
🔹 Chainlink VRF + fulfillRandomWords
🔹 % Ops (modulus)
🔹 Enums
Adding new habit of reading through the ‘Written Lessons’ ahead of the video.

✅Day 49/100:Rebase Token
i have decided that i'll skip DeFi protocols section and proceed to Rebase Token and I will come back to it immediately I finish the Advanced section course.

Day 45/100 : Winner Logic Added
Today I added pickWinner() to my CustomRaffle.sol contract:
Random winner selection (for now)
Prize payout
Raffle reset
New event logging
#100DaysOfSolidity #BuildInPublic #Web3Dev
✅Day 43/100 : I’m back.
4 weeks off. Exams done.
Now it’s full-time blockchain development again.
Brushing up old projects, sharpening testing skills, and diving into DeFi protocols.
Let’s build. Let’s earn. Let’s ship onchain.
#100DaysOfSolidity #BuildInPublic #Web3Dev
✅ Reviewed Solidity variables & data types
✅ Deployed my first basic contract on Remix
✅ Faced errors — and fixed them!
Every day is a win when you're learning.
Stay consistent. Let’s grow together 💪

Day 16: Foundry Progress w/@CyfrinUpdraft
Got over this part I was stuck on yesterday, about ERC-2335…

Day 12 | 13 of my #Solidity journey with @CyfrinUpdraft
Spent 6+ hrs trying to switch from Remix to Foundry.
BIOS ✅
WSL2 ❌ crash
WSL1 ❌ errors
System recovered but setup failed.
Learned a ton about my dev environment.
Tomorrow, new approach.
#100DaysOfSolidity
Finally repaired my laptop 😮💨
I’ll be pausing my #100DaysOfSolidity journey for now to focus on Rust.
So far, we’ve covered Chapters 1–4 of The Rust Programming Language, and I must say ownership has been one of the most interesting concepts so far.

🧵 Day 5 of #100DaysOfSolidity
Today I'll be diving into the core of any smart contract — functions.
Let’s break down what I learned 👇
🔧 Grinding from my mechanical workshop office…
Today’s deep dive:
UUPS vs Transparent vs Beacon vs Minimal proxies in Solidity
Detecting contracts with msg.sender == tx.origin & address.code.length
