A signature request pops up on the page. It doesn’t cost any Gas—what happens if I click it?
This is how I understand it: many people think that signing without paying a fee won’t affect their assets. Permit approvals via off-chain signatures exploit exactly this misconception.
Not all tokens support Permit. A common stablecoin, USDC, supports this type of signature-based approval on Ethereum.
What I do: when a signature request contains fields such as Permit, spender, amount, and deadline, I treat it as an approval.
Looking at the market: $ETH reports 2047.7, 24h -1.86%.
