On X it is cheap to stand up @Uniswap_Help with the same avatar. A checkmark is no longer proof: people buy it. A link in a reply under the protocol's tweet is the most common door into a fake Uniswap.

The picture is a diagram. In life the difference is often one character: 1 instead of l, an extra _support.
Where to get the handle if not from search
- The site you already checked (a bookmark). Header or footer has an X icon. Open it, remember the handle, save it.
- The protocol card on DefiLlama: the Twitter field goes to the same place.
- Only then search on X, and only to match letters against what you already have.
Not the other way around: do not search “Uniswap twitter”, do not tap the first promo.
What to look at in the profile
- The handle character by character:
@Uniswapis not@Unlswapis not@Uniswap_Help. - The website in the profile header matches the domain from your bookmark (
app.uniswap.org,jup.ag,metamask.io). - The pinned tweet points at that same domain, not
connect-wallet-airdrop. - Replies under the thread are strangers. Do not open links from there.
