Check and Revoke Your Smart Contract Approvals

Check the smart contract to which you granted permissions now that the new year has brought new resolutions. I have approved many smart contracts during staking, providing liquidity, or just while moving my funds. Today it was time to check the approved smart contracts.

Almost all of my authorizations were for limitless amounts. In an effort to avoid any potential problems, I canceled almost all of my approvals.

You should to at the very least review your permissions and perhaps revoke them. The reason for that is that someone may have unintentionally accepted a malicious contract that is only waiting for a particular amount of funds to steal, or a hacker may discover a flaw in a contract that is acting properly and find a way to exploit it. It will be always necessary to connect your wallet on the listed website to rewoke the smart contracts.
