Useful tip: off-chain signature approvals
These signatures are not on-chain transactions, so signing them doesn’t cost any Gas. However, whoever obtains the signature can submit it on-chain to make the approval take effect.
Not all tokens support permit. A common stablecoin, USDC, supports this type of signature approval on Ethereum.
If an unfamiliar website asks you to sign something to claim an airdrop, it’s best to stop and think first.
Finally, a market update: $ETH is at 2450.22 (24h +2.57%).
