ChainGuard

ChainGuard protects your crypto wallets by scanning for dangerous token approvals across multiple blockchains.

Every time you interact with a DeFi protocol, you grant token approvals that can put your funds at risk. Forgotten unlimited approvals to unverified contracts are the #1 cause of wallet drains. ChainGuard finds them and helps you revoke them.
