Day 34/100 Continued learning about blockchain bridges today. Still trying to understand the full flow properly between chains. Complex topic, but interesting. #100DaysOfCode #Web3

Day 33/100 Revised Foundry basics again: - forge - anvil - cast - chisel Also revised: - payable functions - call & transfer - receive & fallback functions Good revision day. #100DaysOfCode #Solidity

Day 32/100 Learned about: - IERC20 interface - lock contracts a bit more - Wormhole attack Interesting to see how small mistakes in bridges can lead to huge exploits. #100DaysOfCode #Solidity

Day 31/100 Continued learning about bridges today. Understood the idea of lock contracts a bit better. Not gonna lie, this topic is getting difficult 😅 Going slow, but still going. #100DaysOfCode #Web3

I want to start an AI + Web3 community for builders. This will be a space for people to share killer use cases, AI agents/workflows, onchain apps, hackathons, grants, fellowships, jobs, global events and builder resources. A place where builders actually help builders. Comment “builder” if you want to join.

Day 30/100 Learned about NFTs and cross-chain bridges today. Tried understanding how assets move between chains like Ethereum ↔ Solana. Pretty difficult topic honestly, but interesting. #100DaysOfCode #Web3

Day 29/100 More Foundry testing + deployment today. - deal, hoax - startPrank / stopPrank - deployed contract on Sepolia using forge + RPC Nice to see things working on testnet. #100DaysOfCode #Solidity

Day 28/100 Learned event testing in Foundry. - vm.expectEmit(...) - checking indexed topics + data in logs - console.log from forge-std Getting better at verifying contract behavior through logs. #100DaysOfCode #Solidity

Day 27/100 Learned Foundry testing today. - vm.prank (simulate different msg.sender) - vm.expectRevert (test failure cases) Nice to test both success and failure paths. #100DaysOfCode #Solidity

Day 26/100 Explored Foundry today. - forge, cast, anvil, chisel - setup & installation - running tests locally Nice to actually run tests in a local environment. #100DaysOfCode #Solidity

Day 25/100 Learned the differences between: Ganache vs Hardhat vs Foundry vs Truffle Only theory for now, but getting an idea of the dev tools ecosystem. #100DaysOfCode #Solidity

Day 24/100 Learned the difference between Ethereum and Polygon. Polygon is faster/cheaper, but relies on its own validators and then settles data back to Ethereum. Interesting trade-offs between cost, speed, and decentralization. #100DaysOfCode #Ethereum

Day 23/100 Learned about tokens on Ethereum today. Also created a token contract from scratch. Good session understanding how tokens work beyond just using them. #100DaysOfCode #Solidity #Ethereum #Blockchain

Day 22/100 Deployed my Web3 dApp on Vercel: faucet-eth.vercel.app (Not exactly a faucet, more of a dApp 😄) Also uploaded my Will Contract code to GitHub. Small progress daily. #100DaysOfCode #Web3

Day 21/100 Built a simple Will Contract in Solidity. - owner deposits ETH - predefined recipient added - if owner becomes inactive, recipient can claim funds - used OpenZeppelin as well Interesting project combining logic + real use case. #100DaysOfCode #Solidity

Day 19/100 Learned about OpenZeppelin today. Covered: - audited contracts library - importing reusable contracts - Ownable.sol use cases Helpful to use trusted building blocks instead of rewriting everything. #100DaysOfCode #Solidity #openzeppelin

Day 18/100 Learned more Solidity today. Covered: - onlyOwner modifier - virtual functions - overriding parent contract functions in child contracts Nice to see access control + inheritance concepts together. #100DaysOfCode #Solidity

Day 17/100 Did some Solidity revision today. Revisited: - structs - mappings Good to review the basics before moving ahead. #100DaysOfCode #Solidity

Day 16/100 Learned about EVM architecture today. Covered how the Ethereum Virtual Machine is structured and how contracts execute inside it. Understanding internals slowly. #100DaysOfCode #Ethereum

Day 15/100 Back to Ethereum fundamentals today. Covered: - types of accounts - world state - EVM - Solidity - bytecode, opcodes - ABI Understanding what happens behind the scenes is important. #100DaysOfCode #Ethereum #Blockchain
