When I built my first decentralized app, I had visions of disrupting DeFi, scaling NFTs, and maybe even minting the next viral meme token.
Instead, I built... a simple "read/write" contract that stored notes on-chain.
And it was the smartest decision I could’ve made.
🚧 Chasing Complexity (Too Early)
Before I understood Solidity properly, I was already sketching ideas for lending protocols and on-chain games. But something kept nagging at me:
- How do contracts store data long term?
- What happens if a write fails?
- How do I debug transactions after they succeed but don’t behave as expected?
The more I experimented, the more I realized I was skipping the basics.
So I did something "boring."
📝 The DApp That Just Stored Notes
I built a minimal dApp that did exactly two things:
addNote(string memory content)-
getNotes()returns a list of notes
Each note was tied to msg.sender. Just text — no tokens, no randomness, no cross-chain hype.
But this boring dApp taught me everything I needed to know:
- How contract storage works
- How to handle mappings and arrays
- Why gas costs matter
- How to emit logs for frontends
- How to test using Sepolia and Hardhat
🔥 What I Learned (That You Probably Won’t Get From Tutorials)
1. Solidity is deceptively simple
It looks like JavaScript. But one wrong storage pattern can wreck your gas costs or leave your data permanently stuck.
2. Gas fees matter
Even with just notes, writing to storage is expensive. I optimized my code after seeing a 3x gas difference between versions.
3. Logs are your best friend
Return values can’t be tracked after a tx — only events show what actually happened.
4. Simplicity = speed of learning
Because the app was small, I iterated faster, caught bugs early, and deployed to mainnet with confidence.
🧠 My Advice: Keep It Boring
If you're building your first dApp, try something simple:
- A to-do list
- A URL shortener
- A basic registry
- A voting system without tokens
Focus on data storage, permissions, events, and deployment flow.
Learn the mechanics — not the hype.
🚀 What’s Next?
Now that I’ve got the basics locked in, I’m building toward:
- Upgradeable contracts
- Modular smart contracts with Diamond pattern
- Cross-chain message passing
- Real-time indexing with The Graph
But I wouldn’t have gotten here without starting boring.
