Revoke Approval

The act of removing a previously granted token spending permission from a program or delegate, preventing it from transferring your tokens in the future. Revoking approvals is an important security practice after interacting with DeFi protocols, especially unfamiliar ones, because outstanding approvals could be exploited if the approved program is compromised. On Solana, tools like Revoke.cash and wallet-built-in features allow users to view and revoke active token approvals.
