To revoke is to withdraw a permission you previously gave. Since token approvals stay active until cancelled, revoking is how you shut the door on contracts you no longer use or trust. It is an on-chain transaction that resets the allowance for a specific token and contract back to zero.<\/p>\n
This matters as basic wallet hygiene. Over time, active wallets accumulate many approvals from various apps, and each one is a potential liability if that contract turns out to be malicious or gets exploited later.<\/p>\n
Example: after using a new DEX once, you check your approvals with a trusted tool and revoke the unlimited spending permission you granted, so the contract can no longer touch that token.<\/p>\n
Safety note: make revoking a habit, especially after interacting with new or unaudited contracts, and immediately after any suspected scam interaction. Use only well-known, verified approval-management tools, since fake “revoke” sites are themselves drainers. Revoking costs a small gas fee, but it is cheap insurance against a future drain. Related terms include token approval, wallet-drainer, gas fee, and smart contract.<\/p>\n","protected":false},"excerpt":{"rendered":"
