ERC-20 Approval
Detects when a contract or address receives a spending allowance. Effectively unlimited amounts are marked critical.
Exactly what Protect monitors
Protect follows new permission events emitted on Base after a wallet is enrolled.
Current coverage
ApprovalForAll
Detects when an operator gains or loses global access to an NFT collection.
Monitoring status
Shows the last checked block, any RPC errors and an alert history.
How it works
- Add a public Base address. No connection or signature is requested.
- Protect follows new blocks. Monitoring starts at the current block after several confirmations.
- Review alerts. Each entry shows the contract, operator, risk level and BaseScan transaction.
Important limits
- Protect does not automatically reconstruct every historical permission that was already active.
- It cannot block, revoke or sign a transaction.
- An alert shows that a permission changed; it is not proof of fraud.
- To check a transaction before signing, use Machine Preflight.
