What is revoking approvals?
Whenever you use a decentralized exchange or dApp, it is granted access to move tokens on behalf of the user. In the case of a DEX, users need to sign an approval that will help the smart contract complete the trades.
Even though granting permission is necessary to some extent for some processes, you can always revoke smart contract permissions. Granting token approvals to trusted DEXs is fine. However, not all platforms are safe, and sometimes users have to reduce the risks to stay on the safe side by revoking approvals. Let us take the example of MetaMask to see how we can revoke approvals.
