Quick question regarding the airdrop. If you haven't traded on uniswap before is it too late to receive the airdrop? Is there a link where I can find more information (I checked already)?
If you're referring to 400 uni giveaway which is going on right now - you can claim your free 400 UNI only if you traded on uniswap at least once.
That is the only information I personally have, you should re-check this
