1
The "Unlimited" Trap
Most Dapps ask for "Unlimited Allowance" to save gas. This gives them permission to take ALL your USDT whenever they want.
2
Use a Scanner
Go to Revoke.cash or Etherscan Token Approvals. Connect your wallet. It will show every contract that has access to your funds.
3
Revoke High-Risk Spenders
See an old contract you don't use? REVOKE it. See a sketchy "Mining Pool"? REVOKE it.
4
The Cost
Revoking costs gas (ETH/BNB). It is an on-chain transaction. Consider it insurance for your life savings.
Common Questions
Q: Does disconnecting my wallet revoke permissions?
NO! Disconnecting only changes the UI. The blockchain permission remains FOREVER until you revoke it.
