Check if your wallet still has unclaimed UNI from the 2020 airdrop
In September 2020 Uniswap gave 400 UNI (more for liquidity providers) to everyone who had used it. The claim contract has no deadline and no way to take the tokens back. About 12.5 million UNI is still unclaimed, spread over roughly 30,000 wallets.
Paste an address below. We look it up in Uniswap's own published Merkle data and read the contract to see whether it was already claimed. The official claim page is gone, so the full report gives you the index, amount and proof Uniswap's manual-claim guide asks for.

Official source: Uniswap's official manual-claim guide. We also check every other source below in the same lookup.
Paste a public wallet address. We check official project data for airdrops, reward distributions, refunds and forgotten balances it can still claim, and tell you for free how many there are and roughly what they're worth. The full report (which ones, amounts, deadlines and official claim links) is 0.75 USDC on Base. If there's nothing to claim, we say so and you pay nothing.
- Nobody legitimate will ever ask for your seed phrase or private key. Not us, not any project, not 'support'.
- Type claim sites yourself or use the links in this report, which point only to each project's official page. Never use claim links from DMs, replies, ads or search ads.
- A real claim asks you to sign one claim transaction or a plain message. If a page asks for an unlimited token approval, a 'setApprovalForAll', or to send tokens first, close it.
- 'Gas fee' or 'unlock fee' requests paid to a person are scams. Check that the claim is worth more than the network fee before you sign.
