“It’s not that Web3 is hard. It’s just that everything you think you know — changes.”
💭 The Misconception
When I first dipped into Web3, I thought I needed to unlearn everything:
- Solidity looked strange
- Wallets felt clunky
- Testing was painful
- And don’t get me started on
uint256
But the truth is: Web3 development isn’t hard. It’s just... different.
And once you stop comparing it directly to Web2, it actually becomes exciting.
🧱 What’s Actually Different?
Let’s break it down:
1. No Backend? Wrong — the Backend is the Blockchain
In Web2, the backend is your server or cloud stack.
In Web3, the smart contract is your backend — deployed on Ethereum, Polygon, etc.
- You can’t patch code (unless you build for upgrades)
- Everything is public
- Every state change costs gas
✅ You don’t write to a database — you write to an immutable ledger.
2. Frontend Stays Familiar — But Needs to Be Wallet-Aware
Your React/Vue app still works. You still use JavaScript.
The difference?
- You don’t log in — you connect a wallet
- You don’t call an API — you call a smart contract
- You don’t store state off-chain — you watch the chain for changes
Learning libraries like ethers.js, viem, or wagmi bridges the gap.
3. Testing Is Less "Unit", More "Chain Simulation"
Forget mocking a function call.
In Web3, you want to simulate real transactions:
- Will this revert?
- How much gas will this use?
- Does it behave differently when called from another contract?
Tools like Hardhat, Foundry, and Tenderly help answer these.
4. You Can’t Hide Your Mistakes
There’s no console.log in Solidity (well… kind of).
Every mistake you deploy is public, permanent, and traceable.
But that’s also empowering.
- You write contracts that live forever
- Others can build on them
- Users own their data
It forces you to build like you mean it.
🚀 What Helped Me Transition
Here’s what clicked for me as I went from Web2 to Web3:
- Start simple: deploy a
HelloWorld.solto Sepolia - Learn how to read/write contract state from a frontend
- Don’t chase DeFi complexity — focus on how the chain works
- Use testnets like they’re real. Simulate flows, not just function calls
- Get curious: inspect contracts on Etherscan, decode ABI, watch logs
And the biggest mindset shift?
💡 You’re not just writing code — you’re publishing logic into the world.
🎯 So, Is Web3 Dev Hard?
No.
But it’s unforgiving, transparent, and trustless by design.
And once you embrace that…
You realize how fun, fast, and full of potential it is to build for the chain.
