How can you lose tokens just by signing something when no Gas was spent?
Not all tokens support permit. A common stablecoin, USDC, supports this type of signed authorization on Ethereum.
The signature itself is not recorded on-chain, so signing does not require Gas. But whoever obtains the signature can submit it to the blockchain to activate the authorization.
The most important thing to remember when managing funds: check the authorized address and spending limit carefully before signing. If the address is unfamiliar or the limit is outrageous, reject it.
