Finally i complete basic of solidity smart contract development course its time learn more let's go....

Completed the 5 hours Solidity 101 course.

Finally Done with Solidity 101

Getting Knowledge day by day☺️ Today I earned my "Write Ethereum smart contracts by using Solidity" badge! It's kind of fun studying through documentations provided by @MicrosoftLearn journey! #web3 #solidity

It was fun taking the Smart contract development with Solidity on Cyfrin Updraft. During the course, I learned how to 1. make functions payable in order to receive etherem to the smart contract. 2. use 'require' statements to revert previous actions if a condition is not met. 3. get external data (Price feed) from chainlink into the smart contract 4. interact with external contracts, using the contract address and the abi. Interfaces also help interact easily with the contract's methods. 5. make use of the Fallback function and the Receive Function. 6. Different ways to withdraw money from a smart contract: send, transfer, and call methods. 7. save gas by making use of immutable and constant variables 8. import libraries and make use of custom libraries and using it in a smart contract 9. create custom errors. Next to Foundry 101, alongside Speedrun🥳

It was fun learning the basis of solidity, you can also join Cyfrin to learn more about solidity

Quick Introduction to Smart Contracts with Solidity

🚀 New article out! Master the art of debugging deployed Solidity Smart Contracts with this step-by-step guide! 🛠 Say goodbye to on-chain headaches and hello to smooth protocol integrations! Essential for every Solidity dev. #Solidity #DeFi #SmartContracts #Debugging

Hello World ! This is what I learnt this week in Solidity. Check out my articles on Hashnode ( https://lnkd.in/gfAEXRuE ) and DEV ( https://lnkd.in/gdGEKMYJ ).

🎉 New Solidity Challenges! Three fresh exploits are ready to test your skills. Think you can solve them? Or better yet, create your own challenge and prove your expertise! 1️⃣ Exploit 11 - Sideline An exclusive token airdrop is on the horizon, requiring users to register to receive the token. However, external contracts are not permitted on the list. Your task? Find a way to bypass the restrictions and ensure your contract makes it onto the list. 2️⃣ Exploit 12 - Private Treasure A user has amassed a fortune within a smart contract, but it's secured by a secret key. Your task is to test the strength of this key: is it truly secure? 3️⃣ Exploit 13 - Instigator This contract holds a hidden path to its own destruction. Discover the way to trigger its demise and claim what remains.
