🔐 Your Wallet Is Disconnected… But Is Your Crypto Still at Risk?
One thing I’m learning about crypto security is that disconnecting a wallet from a website doesn’t necessarily remove the permissions you’ve already granted.
These permissions are called Token Approvals.
Here’s what I’ve learned:
🔹 What is a token approval?
It’s permission you give a smart contract or another spender to transfer a specified amount of certain tokens from your wallet.
🔹 Why can it be risky?
Some approvals allow unlimited spending. If the approved spender is malicious or becomes compromised, your tokens could be at risk.
🔹 Does disconnecting your wallet remove approvals?
Not necessarily. Token approvals are recorded on the blockchain and can remain active after disconnecting.
🔹 What can we do?
✅ Review existing token approvals.
✅ Check which contracts have spending permissions.
✅ Avoid unnecessary unlimited approvals.
✅ Revoke permissions you no longer need using trusted tools.
⚠️ Revoking an approval usually requires an on-chain transaction and a network fee.
💡 My takeaway:
Wallet security isn’t only about protecting private keys. It’s also about understanding the permissions we grant.
I’m learning crypto step by step, and this is one security habit worth remembering.
❓ Have you ever checked which smart contracts have permission to spend your tokens?
