Blockchain Basics on @CyfrinUpdraft: 30/30! 🎯🦾

Not easy, but a total gamechanger. Replacing middlemen with verifiable code is a massive shift. 🌐🏗️

Foundation is rock solid. Next stop: Solidity. 🏗️💻

How did you start your Web3 journey? 👇

Continuing my Solidity journey with @CyfrinUpdraft!

Today’s focus: Gas Optimization 🚀

I learned to use constant and immutable to make my code cheaper and cleaner. Every little bit of gas saved counts

@DefiHimanshu @CyfrinUpdraft Thanks! It definitely hits different. Giving it my 100% every day to master this. Let's keep building🔥

Continuing my Solidity journey with @CyfrinUpdraft!

Today I went live, deployed 'FundMe' to the Sepolia testnet using Remix and MetaMask. 🥳

@LessonsFromProd @CyfrinUpdraft Spot on! Keeping it simple for now as I learn the basics, but definitely looking forward to diving into more complex access control soon. Thanks for the heads up🫡

[Bartłomiej Macioch @bartmacioch]

Continuing my Solidity journey with @CyfrinUpdraft!

Today was all about security. I implemented a constructor to set the contract owner and restricted the withdraw function to prevent unauthorized access.💪

Today, I Mastered the 3 ways to send ETH in #Solidity: transfer, send, and call.

Key takeaway: call is the recommended method because it has no gas limit and returns a success boolean.

Still grinding with @CyfrinUpdraft

Implemented the withdraw function and mastered for loops to reset funder records in 'FundMe'.
Crucial for keeping the contract state clean🫡

@KalantariAria @CyfrinUpdraft Thanks for the heads up! I'll check it out🫡

[Bartłomiej Macioch @bartmacioch]

Coffee, Remix, and more Solidity🫡

Still grinding through 'FundMe' on @CyfrinUpdraft. No shortcuts, just consistency

@aussiExau @CyfrinUpdraft Thanks! Shaping up great, no surprises so far🫡

[Bartłomiej Macioch @bartmacioch]

Today I worked with PriceConverter and tested Solidity libraries. It’s so useful to keep the code organized and clean

Coolest part? I can now call functions directly on uint256🤯

Back to work now, still a lot to do with 'FundMe' on @CyfrinUpdraft

[Bartłomiej Macioch @bartmacioch]

Still working on 'FundMe' with @CyfrinUpdraft!

Just implemented a contributor tracking system! Using msg.sender combined with arrays and mappings.

The contract now registers every address sending ETH, maps each sender to their total contribution.🫡

Building „FundMe” with @CyfrinUpdraft!

My new smart contract will:

- Collect community funds
- Secure withdrawals
- Verify payment value based on real-time USD price

Time to start exploring the power of @chainlink! 🔥

@iamsaniydv definitely at night🌛

[Bartłomiej Macioch @bartmacioch]

Diving deep into @chainlink Price Feeds with @CyfrinUpdraft!

Working on ‚FundMe’ integrated the AggregatorV3Interface and version check. Now building the logic to fetch real-time ETH/USD prices.

Managing precision in Solidity is a challenge, but I'm loving the process! 🚀

[Bartłomiej Macioch @bartmacioch]

@asen_sec Love this mindset!
After how much time into your journey did you start seeing the first real results?

@TheBlockChainer that is so true 💯

[Bartłomiej Macioch @bartmacioch]

@yap2earn @CyfrinUpdraft True, the beginning is always a test of will. Keep pushing and good luck on your journey! 👊

[Bartłomiej Macioch @bartmacioch]

Consistency and constant practice, that’s my focus right now.

I’m starting to see real results in my Solidity journey and it feels amazing. Sticking to the routine is the only way to succeed. 🚀

Thanks @CyfrinUpdraft for the resources!
