📐 Wallet & Security | Off-chain Signature Authorization
· Key point: Phishing websites often set the authorization amount to the maximum and the expiration time far in the future. Signing it is equivalent to handing over the right to use those tokens.
· How to understand it: Once a Permit signature is submitted on-chain, it works just like a regular authorization (approve). The authorized party can transfer tokens up to the approved amount.
· Practical tip: When a signing request includes fields such as Permit, spender, amount, and deadline, treat it as an authorization.
