Built my first real Web3 project 👇 A multi-chain crypto wallet (ETH, SOL, BTC) 🔹Mnemonic-based wallet (BIP-39/44) 🔹Live balances + send transactions 🔹UTXO handling for Bitcoin 🔹Custom UI Still early in Web3, but this helped a lot. #web3‌‌ #blockchain #cryptowallet

Today I learned about the “oracle problem” in blockchain. Blockchains can’t access real-world data on their own… that’s where oracles come in. But centralized oracles = single point of failure Solution? Decentralized Oracle Networks (DONs) like Chainlink 🔗 #Blockchain #Web3

Deployed my first token on testnet today using OpenZeppelin to write the crypto currency contract. What’s the FIRST thing you’d test on a fresh contract? #Web3 #Solidity #Ethereum #OpenZeppelin #BuildInPublic #Testnet #Blockchain

Building from scratch hits different. 🔥 Today I coded my own ERC-20 crypto without OpenZeppelin. Mind blown by the approve() trap: blocking 0 allowances traps users, no way to revoke DEX access. What's the toughest Solidity concept you've faced? #Web3 #Blockchain #Crypto

If you’re a backend engineer, this shift will change how you think about systems forever. What surprised you most about blockchain architecture? 👀 #Web3 #Blockchain #BackendEngineering #DistributedSystems #Solidity #CryptoDev @ashishasmit0303/the-anatomy-of-blockchain-security-double-spending-merkle-trees-and-cryptographic-keys-5f99b55c4dcd" target="_blank" rel="nofollow noopener">medium.com/@ashishasmit03…

Most people think blockchain = crypto 💰 But it’s actually a masterclass in distributed systems How do you prevent double spending… WITHOUT a central authority? How do light clients verify transactions… WITHOUT downloading the full chain? Quick breakdown 👇 #Web3 #Blockchain

ERC20 basically makes every token follow the same rules It lets apps use your tokens without owning them Also where things can go wrong if permissions are careless Do you think DeFi would exist like this without ERC20 #Crypto #DeFiDiscussion

Most people use tokens on Ethereum but don’t realize this Early on, every token had different rules Apps had to write custom code for each one That doesn’t scale ERC20 fixed it with one shared standard Simple idea, massive impact #Ethereum #Web3 #LearnInPublic #Blockchain

@Abdulrahee84158 Thank you 🙌

@AshishAsmit Cool project!

What if voting systems were tamper-proof, transparent and fully on-chain? Just built my first Voting DApp in Solidity. From registering voters to preventing double voting and declaring a winner, all handled by a smart contract. #Solidity #Web3 #BuildInPublic #Dapp #Voting

@RV_Programmer That's solid! Mimicking attack scenarios is the real testing.

@AshishAsmit For me it was moving from writing logic to writing invariants and attack scenarios. That’s when testing actually started catching real issues

Testing smart contracts completely changed my perspective today. The biggest takeaway is that testing is not about making the contract work. It is about trying your hardest to break it. What was your biggest lightbulb moment with security? #web3 #solidity #buildinpublic

Spent the day in Hardhat testing smart contracts Learned 'describe', 'it', 'expect' and wrote tests to break my code wrong payments out of stock edge cases Here is a look at the actual output.

@LessonsFromProd Thanks a lot. And I totally agree, The moment the full loop works locally, even small design choices feel more intentional. Ignition definitely made the process smoother

That shift from theory to deployed is genuinely different. Local deployment sounds small but you just proved the whole loop works, which most people skip. Modifiers and inheritance doing real work in prod code instead of tutorial code changes how you think about the design. Hardhat Ignition makes that friction disappear.

I wrote a smart contract… and today I actually deployed it locally. That moment when code turns into something real >>> 👇 Started with Solidity basics Improved it using modifiers & inheritance Deployed using Hardhat Ignition ⚒️ #web3 #solidity #buildinpublic #hardhat

Code snippet from the deployment module 👇 Using Hardhat Ignition to deploy + set initial price. Still figuring things out, but getting there.

128-bit entropy → words last bits = checksum wallet recomputes & verifies That’s why 1 wrong word fails. Wrote a deeper breakdown here: @ashishasmit0303/from-pure-chaos-to-public-address-how-your-crypto-wallet-is-born-cd51742b174b" target="_blank" rel="nofollow noopener">medium.com/@ashishasmit03…

You mistype one word in your 12-word seed phrase… wallet says “Invalid” instantly. But it works 100% offline. So who’s checking? It’s a tiny checksum hidden inside the phrase. Now I’m wondering: is such a small checksum really enough to catch errors? #web3 #blockchain #crypto

Built an upgraded Soda Machine smart contract in Solidity today. Applied: 🔹 mappings & struct for user state management 🔹 visibility keywords (public, external) 🔹 interacting with other contracts via interface 🔹 inheritance for pricing logic #Solidity #Web3 #BlockchainDev

Built a SodaMachine smart contract in Solidity today as a basic LLD exercise. Applied: 🔹 modifier for access control 🔹 require for validations 🔹 payable for ETH transactions 🔹 Contract balance & withdrawal logic 🔹 State management #Solidity #Web3 #BlockchainDev

Want to know the math behind this? I wrote a detailed blog explaining the quantum threat, how HD wallets protect us, and why Bitcoin's legacy addresses are built like a fortress. Protect your bags and read the mechanics here: @ashishasmit0303/from-pure-chaos-to-public-address-how-your-crypto-wallet-is-born-cd51742b174b" target="_blank" rel="nofollow noopener">medium.com/@ashishasmit03…

Your Public Key and your Public Address are NOT the same thing. In fact, exposing your actual Public Key could make your wallet vulnerable to future Quantum Computer attacks. This is exactly why you should NEVER reuse a crypto address. 👇
