🔐 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?
