Pump.fun App vs Fomo: Which Social Trading App Should You Use?

They're the same kind of app now

A year ago this comparison would have been a launchpad against an app. Pump.fun was where coins were created; Fomo was one of the places people traded them, with a social feed on top. A lot of Fomo's early volume ran through Pump.fun's bonding curves, and it still does — every such trade pays Pump.fun's pool fees whichever app sends it.

In 2026 Pump.fun moved up into Fomo's layer. Its app added callouts and follows on August 7, Callout Rewards on August 13, Apple Pay buys in July, and on October 17 a platform fee with a referral share. Bankless summed up the relationship in August as partners underneath and competitors on top. The same month, screenshots posted on X by an account called @CLR_Fomo showed what was presented as a Pump.fun contract offering Fomo traders $20,000 up front and up to $30,000 a month to move their trading over; Pump.fun has neither confirmed nor denied it. Whatever its status, it shows how directly the two are competing for the same traders.

So the useful question is no longer "launchpad or app?" Both are apps. The rest of this page compares them on what you'll actually notice: what each trade costs, what the feed shows you, how money gets in and out, and who's behind each one.

Fees: the clearest difference

Each app adds its own fee on top of whatever the coin's pool charges. Pump.fun's is 0.45%, or 0.40% with a referral code, as a straight percentage. Fomo's is 0.50%, or 0.45% with a code, and on Solana it has a minimum: every Fomo route charges 0.95 USDC on trades between 47.50 and 190 USDC, and below 47.50 its cheapest route charges 2%, or 0.10 USDC under 5. Fomo picks the route per trade. With both codes applied:

Fomo's figures assume its 10% code discount also applies to the minimum, as the site's fee calculator does. Rows marked "min" are where Fomo's minimum, not its percentage, sets the fee.

Above 190 USDC the gap is a steady 0.05 points: $0.50 on every $1,000 traded. Below it, Fomo's minimum dominates, and a $50 trade costs about four times as much in app fee on Fomo as on Pump.fun. For frequent trades of tens of dollars, that's the single biggest difference between the two apps.

The pool fee sits on top, and it's identical. Put $100 into a coin still on its Pump.fun bonding curve and the pool takes $1.25 on any app. Add each app's fee with codes applied and the total is about $1.65 on the Pump.fun app, $2.10 on Fomo and $2.15 on Axiom.

Network fees run the other way. Fomo states that it covers Solana gas, priority fees and token rent — the one-time deposit of about 0.002 SOL for holding a new token. The Pump.fun app passes network fees through as their own line on the confirm screen: on a 10 USDC test buy from this site's account on October 20, 2026, that line read 0.159853 USDC, about 1.6% of the trade and more than the platform fee itself. It moves with network load and can include a rent deposit on a coin's first buy, which the app's "Reclaim SOL" tool returns by closing token accounts you've sold out of. Read it as a fixed cost rather than a percentage: on a trade of a few dollars it outweighs the difference in platform fees and Fomo can be the cheaper app, while from a few tens of dollars up the platform-fee gap is the bigger number.

And the history. Pump.fun's app was advertised as zero-fee on Solana until October 17, 2026, and both companies can change their fees whenever they choose. The figures here are dated and sourced; check the confirm screen for the fee line before you trade on either.

The social layer

Both apps are built around watching other traders, but they reward different things. Fomo is built for reading: a live feed of buys and sells, trader profiles with full histories, a leaderboard ranked by results, and Thesis notes where traders explain a position in their own words, plotted on the price chart. It has had more than a year to accumulate track records, and it shows.

The Pump.fun app is built for calling. A callout is a public call on a coin the caller holds, shown with their position and profit, pushed to their followers, and paid through Callout Rewards when other users trade after reading it. Squads, direct messages and a Friends tab followed in September. Early hands-on comparisons in August, such as trader Jonah Blake's on X, rated Fomo's feed as better signal and Pump.fun's as faster but cluttered; Pump.fun has since simplified its home feed for newcomers, and the clutter point is still the fair one.

The incentive difference matters more than the features. Paying callers for the trading they drive rewards persuasion, and a caller always holds what they're calling. Pump.fun's October 10 change, which weighs whether followers profited more heavily than volume, is a step toward rewarding good calls rather than loud ones. Fomo's incentives run through its referral program rather than through posts, which keeps its feed closer to a record of what people actually did. For learning, Fomo's layer is the stronger one; for being paid for your calls, Pump.fun is the one that pays.

Getting money in and out

Fomo signs you up with an Apple ID or Google account, creates a Solana wallet and an EVM wallet, and takes a bank-issued debit card, Apple Pay or a USDC deposit. US users can withdraw straight to a bank account; elsewhere you withdraw to a wallet or an exchange. Its referral code has to go on the sign-up screen.

The Pump.fun app signs you up with email, Google, Apple or GitHub, creates a Privy wallet, and takes Apple Pay or Google Pay purchases or a SOL/USDC deposit; payment methods vary by country. A referral code can go on at sign-up or later, from the Rewards tab on your profile or a trade's fee details, but the deposit match — up to $50, paid over five trading days — counts only when the code goes on before your first card, Apple Pay or Google Pay purchase, so sign-up is still the best moment to add it. The full match terms are on the Pump.fun referral code page.

Both apps cover desktop too: Fomo at fomo.family, Pump.fun at pump.fun, each with the same login as the phone.

Chains, perps and stocks

Fomo is the multi-chain one: Solana, Base, BNB Chain, Monad, Ethereum, Robinhood Chain and Arc from one cash balance, with the routing handled for you. It also offers perpetual futures outside the US.

The Pump.fun app is Solana-first, with EVM trades on Robinhood Chain, HyperEVM and Arc at an extra 0.10–0.15%. It adds Hyperliquid perpetual futures (closed to the US and Ontario) and Robinhood tokenized stocks (closed to the US, UK, Switzerland and Canada), and launching a coin is built into it.

Safety and who's behind them

Custody is a tie: both wallets are self-custodial, so neither company can move your funds, and both let you leave with your assets. The difference is the company.

Fomo is a venture-backed company founded by a team from dYdX, with a $75 million Series B led by Index Ventures in 2026, and no comparable incidents on record — the sourced detail is in is Fomo legit. Pump.fun is far larger by revenue and carries more history: a former employee's exploit in May 2024 (about $1.9 million, with users made whole), a US class action whose RICO claims a judge allowed to proceed on August 31, 2026, a UK ban, and a period in September 2026 when its iPhone app was pulled from new downloads in the US and India. None of that has touched user custody, and an ongoing lawsuit is an allegation, not a finding. It is still more to weigh.

Bankless put its finger on the deeper issue in August: social trading only works if what you see in the feed can be trusted, and the rivalry will come down to which app protects that. That's the right lens for both apps' callouts, leaderboards and theses.

Which one, for whom

• Frequent trades from a few tens of dollars up: the Pump.fun app. Its straight percentage plus the network fee comes in under what Fomo charges at those sizes.
• Trades of a few dollars: Fomo, which pays the Solana network fee for you.
• Pump.fun launches, or launching your own coin: the Pump.fun app, from the team that runs the curve.
• Getting paid for calls: the Pump.fun app, through Callout Rewards.
• Learning from other traders: Fomo. Its feed shows reasoning and longer track records.
• Several chains from one balance, or US bank withdrawals: Fomo.
• In the UK: Pump.fun is off the table there.

Plenty of traders will use both — the accounts are separate, and each takes its own code. If you also want a desktop terminal with deeper analysis than either, that's where Axiom comes in.

Referral disclosure

BullishTBH and iamsmart are both SellThePump's referral codes, and the links in the boxes on this page are referral links: when an account applies one, the platform shares part of that account's fees with the site. The rates in this comparison are the ones each platform publishes, and neither company had any say in the verdict. SellThePump is independent of both. How the site is funded is on the author page.
