Why can you still lose your tokens just by signing something, even though it costs no Gas?
Phishing pages often set the allowance to the maximum and the expiration date far in the future. Signing it is effectively handing over control of those tokens.
This type of signature is not an on-chain transaction, so it doesn’t require Gas when you sign. But the party who obtains your signature can submit it on-chain to activate the approval.
The most important thing to remember when managing your positions: before confirming, check the address you’re authorizing and the allowance amount. If you don’t recognize the address or the amount seems unusual, don’t sign.
