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.

Today I learned how DeFi replaces banks with smart contracts.

Unlike TradFi, DeFi is permissionless, transparent, and runs on deterministic code instead of centralized institutions. Also learned about “Money Legos” — how protocols can stack together to create complex systems.

[Ashish Asmit @AshishAsmit]

Today I learned about smart wallets & EIP-7702.

Normal wallets = user control but not programmable
Smart wallets = programmable but extra setup

EIP-7702 bridges this by letting your wallet act like a smart wallet temporarily.

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 🔗

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?

[Ashish Asmit @AshishAsmit]

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?

If you’re a backend engineer, this shift will change how you think about systems forever.
What surprised you most about blockchain architecture? 👀

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

[Ashish Asmit @AshishAsmit]

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

[Ashish Asmit @AshishAsmit]

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

@Abdulrahee84158 Thank you 🙌

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.

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

[Ashish Asmit @AshishAsmit]

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?

[Ashish Asmit @AshishAsmit]

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.

[Ashish Asmit @AshishAsmit]

@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

[Ashish Asmit @AshishAsmit]

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

[Ashish Asmit @AshishAsmit]

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:
https://t.co/rbMLkQuaId

[Ashish Asmit @AshishAsmit]

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?

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
