Token approval lets a contract spend certain tokens from a wallet, which can be dangerous if the contract is malicious or over-permissioned.
Core ideas
What to understand first
- Approvals are different from simple claims.
- Unlimited approvals can increase risk.
- Some claims should not need approval for unrelated assets.
- Approval risk depends on contract permissions.
Safety checklist
What to check before acting
- Check whether the prompt is an approval.
- Avoid approving unrelated tokens.
- Limit approval amounts when possible.
- Revoke suspicious approvals after interaction.
Risk note
Common mistakes to avoid
- Malicious approvals can drain approved tokens.
- Users often confuse approvals with claims.
- Old approvals can remain active.
