Token revoke refers to the action of rescinding or canceling previously granted permissions for a smart contract or decentralized application to spend or transfer a user’s tokens. This security measure allows users to regain control over their digital assets by removing authorizations given to third-party protocols. It is a critical function for protecting funds from potential vulnerabilities or malicious contract behaviors. Regularly revoking unused permissions enhances wallet security.
Context

Discussions often highlight the importance of regularly reviewing and revoking token approvals to mitigate risks associated with contract exploits or rug pulls. Tools and platforms are continuously developed to simplify the process of managing and revoking token permissions, improving overall user security in Web3.
