The Danger of Infinite Approval
Did you know that many times when you interact with a DeFi protocol, you give permission to spend $USDT of your wallet unlimited and forever?
We do this for convenience so we don't have to approve each transaction, but it's a ticking time bomb. If that protocol suffers a hack in the future, attackers can use that old permission to drain your funds even if you are not connected.
You should have the habit of using tools like Revoke.cash to check which contracts have permission over your coins and revoke access from sites you no longer use.
Keep your wallet clean of old permissions, or you will be leaving the door of your house open.
