How to Revoke Token Approval Safely
Learn how to review and revoke token approvals using trusted tools and block explorers.
Quick answer
What this usually means
Revoking approval removes or reduces a contract's ability to spend a token from your wallet.
Common causes
Why it happens
- A previous DEX or dApp approval is no longer needed.
- The approval was granted to an unknown contract.
- A suspicious site requested unlimited allowance.
- The wallet has old approvals across multiple chains.
Fix path
What to check first
- Use a trusted approval checker for the correct network.
- Review spender addresses carefully.
- Revoke approvals that are unnecessary or suspicious.
- Confirm the revocation transaction in your wallet.
- Repeat the check on other networks you use.
Safety note
Do not make the problem worse
- Revoking approval costs gas.
- Use official or widely trusted approval tools.
- If a seed phrase is exposed, revoking approvals is not enough.
