1. Use Revoke.cash periodically.
It is always good to limit your approvals whenever you are not actively using a dapp, especially for NFT marketplaces. This reduces the risk of losing your funds to hacks or exploits and can also help mitigate the damage of phishing scams.
2. Use Revoke.cash after getting scammed.
Very often, scammers try to trick you into granting them an approval to your funds. Sort your approvals by most recent to find out which approvals are to blame and revoke them to prevent further damage. Unfortunately it is not possible to recover funds that have already been stolen.
3. Use the Revoke.cash browser extension.
Prevention is better than mitigation. The Revoke.cash browser extension warns you when you're about to sign something potentially harmful. This can save you from phishing scams by making you think twice about what you're doing.
