How can I lose coins just by signing, without spending any Gas?
A permit signature specifies the holder, the authorized party, the allowance, the nonce, and the expiration time.
An offline signature includes an expiration time. Before it expires, whoever has the signature can submit it on-chain at any time.
The most important thing to remember when managing funds: if a signing request contains fields like Permit, spender, allowance, and deadline, treat it as an authorization.
