Have you ever had this moment:
After creating the wallet not long ago, ready to grab a popular airdrop, and then with one signature, MetaMask directly pops up a strange URL,
saying 'Confirm Authorization' but you have no idea what you authorized.
I almost fell for it at that time.
That was my first on-chain interaction; it wasn't an airdrop, it was a heartbeat.
When newbies start thinking about going 'on-chain', the easiest pitfall is:
"What address am I actually dealing with? Is this operation really safe?"
Below are the '4 steps you must read before on-chain interaction' that I've summarized after experiencing pitfalls, sharing them for you who are just entering 👇
🧩 1. Check the contract address before interacting
Don't blindly click on official links
Use DeBank or Etherscan to check project address activity
Don't authorize, don't sign, and don't blindly click 'Connect' on unknown contracts
🧩 2. Use separate accounts for interaction
One main wallet: long-term holding, no interactions
One test wallet: only using a small amount of ETH to experiment
Don't use one wallet everywhere, then you won't dare to mention any project when they issue tokens.
🧩 3. Take a screenshot before every operation
For easier tracking and recording later
To prevent confusion in your memory
Now, every time I interact, I take a screenshot + note the time (using Notion + Excel)
🧩 4. Be sure to learn 'authorization cleaning'
Use Revoke.cash to clean up permissions
Be more cautious with multi-chain interactions (ZKsync/Scroll/Linea, etc.)
If not cleaned, the wallet might just belong to someone else
✅ My advice is:
Don't pursue 'big airdrops' right at the beginning; first learn self-protection, then improve interaction efficiency.
On-chain, it's not the newbies that are scary, but after a flurry of operations, realizing your private key is exposed.
