When you use DeFi, you approve contracts to spend your tokens. Old or malicious approvals can drain your wallet. Regularly revoke unused approvals.
Why Revoke Approvals?
Risks of Old Approvals:
- Hacked protocols can drain approved tokens
- Malicious sites can steal funds
- Unlimited approvals are especially risky
