How to check token approvals
A token approval lets a contract spend a token from your wallet up to a specific allowance. This is common in DeFi, but old or unlimited approvals should be reviewed.
What to review
- The spender address or app name.
- The token being approved.
- The allowance amount, especially unlimited approvals.
- Whether you still use the app.
Where to check
