What are Fomo X Cashtags?
Fomo X Cashtags are the Trade on fomo button that X shows on the cashtag of every Solana token since November 10, 2026. Tap a cashtag in a post, check the price and chart, tap the button, and the token opens in Fomo ready to buy or sell.
How do X Cashtags work with Fomo?
A cashtag is a ticker with a dollar sign in front of it, like $SOL or $WIF. X turned cashtags into small market pages in April 2026, starting with iPhone users in the US and Canada: tap one and you get the price, a chart and the posts about that asset. In September 2026 it added a Trade button for US users that hands you to a partner, first Coinbase, Kraken, Gemini, Interactive Brokers and Moomoo.
Fomo joined on November 10, 2026, and it covers the part the exchanges do not: every token on Solana. On the cashtag page of a Solana token the button reads Trade on fomo. In Fomo's launch clip it opens that token in the Fomo app, with its chart, its holders and the Buy and Sell buttons, and from there it is a normal Fomo trade.
X does not run the trade or hold your cash. The order goes through Fomo's wallet, which is self-custodial: the key is yours and you can export it. The Fomo wallet page explains how that works.
What the Trade on fomo button changes
The button shortens the way to a trade that is otherwise the usual Fomo one.
No copying a contract address
Before, you copied the ticker or the address from a post, opened a trading app and searched for it. Now the cashtag carries the token, and the button opens the right page.
Every Solana token with a pool
The exchange partners on X sell the coins they have listed. Fomo trades any Solana token that has a pool, which covers the memecoins people post about. The Fomo meme coins page shows what that list looks like.
Gas paid on Solana
You do not need SOL in the wallet to pay for the transaction. Fomo pays the gas, the priority fee and the token rent on Solana, and you pay one fee in dollars.
The feed on the other side
The token page in Fomo shows who holds the coin, what they paid and what they wrote about it. After a buy the app offers Add thesis, so you can post your own reason next to the trade.
How to trade a Solana token from X on Fomo

What does a trade from an X cashtag cost on Fomo?
Fomo announced no separate fee for trades that start on X, so the normal Solana schedule applies: one fee in dollars, with the network cost paid by Fomo.
| Trade size | Fomo fee | Gas |
|---|---|---|
| $3 | $0.10 | Paid by Fomo |
| $20 | $0.40 (2%) | Paid by Fomo |
| $100 | $0.95 | Paid by Fomo |
| $500 | $2.50 (0.50%) | Paid by Fomo |
| $2,000 | $10.00 (0.50%) | Paid by Fomo |
From $190 a trade, referral code GEMQUEENX turns the 0.50% into 0.45%, so the $500 buy costs $2.25 and the $2,000 buy costs $9.00. SOL itself sits in the Crypto tab, where the fee is 0.05%. The full schedule is on the Fomo fees page, and the referral code page shows where to type the code.
Fomo next to the other Trade partners on X
X does not trade anything itself. The partners behind the button differ in what they sell and in who holds it.
| Fomo | Coinbase, Kraken, Gemini | Interactive Brokers, Moomoo | |
|---|---|---|---|
| On X since | November 10, 2026 | September 15, 2026 | September 15, 2026 |
| What it trades | Any Solana token | The coins each exchange lists | Stocks and ETFs |
| Who holds the assets | You, in a self-custodial wallet | The exchange | The broker |
| Identity check | None to trade | Yes | Yes |
| Where | Not stated | US, on mobile | US, on mobile |
If the coin is BTC or ETH and you already have an exchange account, the exchange button is fine. For a Solana memecoin that no exchange lists, the Fomo button is the one that can trade it. The Fomo Solana page covers the chain in full.
What Fomo X Cashtags do not do
First, nobody has said where the button shows. X launched its Trade button for US users on mobile, and neither Fomo nor Solana named countries or devices on November 10, so you may not see it yet. Second, the launch is Solana only. Fomo's post names no other chain, so do not expect the button on a Base, BNB Chain or Ethereum token. Third, a button under a viral post is the fastest way to buy a coin at its top, because everyone who bought before you has already read that post. The button saves thirty seconds of searching and tells you nothing about whether the trade is any good.
Fomo's real button is inside X, on the cashtag page. A reply, a DM or an ad that says "trade on fomo" and links somewhere else is not this feature. Fomo never asks for your private key or login code.
Buying a memecoin from a post on X, before and after the button
Most memecoin trades start the same way. Someone you follow posts a ticker, the replies fill up, and you go looking for the coin in another app. That trip between the post and the trade has always been the clumsy part: copy the address, switch apps, paste, check that it is the right token and not the copy that launched an hour later. People get it wrong, and copycat tokens count on that.
The Trade on fomo button removes that trip for Solana tokens. We think it is the most useful thing to happen to cashtags since X made them tappable, and the reason is the token list. Coinbase, Kraken and Gemini have been behind the Trade button since September, and they are fine for bitcoin. They do not list the coin that launched this morning, and that is the coin people on X are posting about. Fomo trades anything on Solana with a pool, that coin included.
It also suits how Fomo already works. The app is a feed of named traders and their positions, so a person who arrives from a post lands on a page that shows who else holds the coin and what they paid, which the post did not tell them.
The worry is speed. Thirty seconds of friction used to give people a moment to think, and some of the worst buys in crypto happen in the minute after a post goes viral. Fomo puts warning labels on thin and unverified tokens, and they sit right above the Buy button, but a label does not stop a determined tap. If you use this, decide your size before you open X.
Neither company has said which countries or devices get the button, and X started its trading links in the US. If it is not there for you, nothing is broken. Open Fomo and search the same ticker; the trade and the fee are identical.
