FOMO vs Pump fun turned into a bridge war this week. On October 21, 2026, Pump.fun replaced Relay with its own Pump Bridge and published data claiming 2x faster buys and 92% fewer errors than Relay, the bridge FOMO was using. One day later FOMO announced its own in-house bridge and router, claiming crosschain trades now land in under one second. Pump.fun charges 0.45% per trade, FOMO charges 0.50%, and both apps let you trade memes across chains from one balance without bridging yourself.
That is the short answer. The longer one needs context, because Alon named FOMO three times in his post, and FOMO answered within 24 hours. I trade on FOMO every day and have used Pump.fun for years, so let’s look at what both sides actually proved.
What Alon Posted, and Why It Targets FOMO
Pump.fun added crosschain trading to its app around May 2026, late compared to FOMO. Since then, every buy on Robinhood Chain, BSC, Base, Arc or Ink went through Relay, the intent-based bridge FOMO was running at the time. Users complained for months about slow and failed buys, so the team built Pump Bridge and ran a head-to-head test.
Here is what Pump.fun says Relay delivered inside its own app:
- 11.2% of crosschain buys hit an error, more than 1 in 9
- A typical buy took 3.88 seconds, and the slowest 10% took over 7.36 seconds
- Fills landed about 3.6% below the displayed price
Pump Bridge, by their numbers, brings a typical buy down to 1.95 seconds, cuts buy errors to 0.9%, and fills about 3% below the displayed price. The fastest 10% of Pump Bridge buys land in 1.23 seconds. There are also no extra bridging fees on top of the platform fee for now.
The post ends with a direct pitch: lowest platform fee of any social trading app, Callout Rewards paying at least $300k per day, a referral boost that pays 100% of platform fees, and $50 for you and a friend after they deposit and trade. In short, Alon turned a technical upgrade into a recruitment post aimed at FOMO’s user base.
How Pump.fun Ran the Test
Credit where it is due: Pump.fun published the raw data. Between September 28 and October 7, users of the Pump.fun mobile app were randomly assigned to Relay or Pump Bridge for crosschain trades, and reassigned several times. The sample covers 416,669 trade outcomes, including 383,326 timed trades measured from tap to the success notification. Roughly 53% of those were on Robinhood Chain and 39% on BSC. Fill quality was measured on 35,333 completed USDC buys under $500. Ethereum was excluded.
One detail matters a lot, however. This test ran inside the Pump.fun app. It measured Relay as Pump.fun integrated it, not FOMO’s app. Bridge performance depends on the integration, the routing, the chains and the trade sizes. So the headline “FOMO’s bridge fails 1 in 9 times” is not what the data proves. The data proves Relay through Pump.fun’s old setup failed that often.
Also, the comparison is already dated. FOMO says it quietly moved a small share of users to its own bridge about a week before Alon’s post, and it went public the day after. If you want the mechanics of how an intent-based bridge works, our explainer on what a crypto bridge is covers it in plain language.
FOMO’s Answer: Its Own Bridge and Router
On October 22, FOMO announced the public rollout of fomo bridge, its in-house crosschain layer. The claims are big: crosschain transactions now land in under one second, execution up to 50% faster than any existing solution, and more than 10x the crosschain transaction count of any other trading app.
FOMO also makes a point Pump.fun did not. Bridging is only half of a crosschain trade. The other half is routing, meaning which pool and path your swap takes on the destination chain. FOMO now runs its own router too, and claims it improves execution by 0.5% on average and lifts the worst 10% of trades by over 2%. By their account, FOMO is the only major crosschain app that owns both bridging and routing, which lets it shave latency at every step: pricing, indexing, bridging and routing.
The team argues that speed only matters during volatility, when every bridge gets slow, and says its stack is built for exactly those moments. To back the speed claim, FOMO did not publish its own CSVs. Instead it pointed to a public Dune dashboard that Relay built, which is where this story gets interesting.
What Relay’s Dune Dashboard Shows
Relay, the bridge both apps just dumped, published a Dune dashboard comparing FOMO and Pump.fun crosschain latency over the last 30 days, built purely from on-chain data. It tracks four modes on Solana to Robinhood Chain, BNB and Base: FOMO via Relay, FOMO via Mobula, Pump.fun via Relay and Pump.fun via Pump Bridge. Relay labels FOMO’s new mode “via Mobula”, and that mode ramped up from October 14, which matches FOMO’s own timeline for its bridge. FOMO has not confirmed what sits under the hood, so treat that label as Relay’s read, not FOMO’s.
Here are the 30-day median buy times, Solana to Robinhood Chain:
- FOMO via Relay: 0.58 seconds, across 2.37 million transfers
- FOMO via Mobula: 0.23 seconds, across 26,448 transfers
- Pump.fun via Relay: 1.16 seconds, across 46,960 transfers
- Pump.fun via Pump Bridge: 0.34 seconds, across 147,722 transfers
Solana to BNB tells the same story. FOMO via Relay sat at 0.79 seconds, Pump.fun via Relay at 1.77 seconds, Pump Bridge at 0.57 seconds, and FOMO’s new mode at 0.45 seconds. Base runs slower for everyone and carries about a second of measurement noise, so I would not read much into it.
What the Numbers Mean for FOMO and Pump.fun
Three things jump out. First, FOMO through Relay was twice as fast as Pump.fun through Relay on the same routes. The bridge was the same, so the gap came from the integration. Alon’s post blamed Relay for a problem that looks like Pump.fun’s own. Second, Pump Bridge is a real upgrade for Pump.fun and does beat FOMO’s old setup on medians. However, FOMO’s new mode beats Pump Bridge on every route, and Pump Bridge has an ugly tail on sells, with a p99 of 9.57 seconds on Robinhood Chain and 31.42 seconds on BNB. Third, the volume claim checks out. FOMO pushed over 4 million Robinhood Chain transfers in 30 days against roughly 440,000 for Pump.fun across both of its modes.
Now the caveats, because this cuts both ways. Relay built this dashboard with an obvious motive, and it says on the page that the figures are not verified against Relay’s own data. It measures only the on-chain bridge leg, from origin block to destination block, not tap to confirmation like Pump.fun’s test. That is why these numbers are far lower than the 1.95 seconds Pump.fun reported. FOMO’s new mode is also capped at around $2,000 per order and has a tiny sample next to its Relay history. Still, it is the only dataset that puts both apps on the same ruler.
My Own Experience on FOMO Crosschain
I have been trading on FOMO daily since my FOMO app review went live, with a lot of that volume on Robinhood Chain and BNB coins. My buys are usually four or five figures. Those land instantly in my experience, and I cannot remember a failed crosschain buy. That was on the old Relay setup, before fomo bridge went public.
That said, I am not a whale blasting six or seven figures into a low cap meme. Bigger orders stress a bridge in ways my size does not, and an 11% error rate would be a disaster for anyone sniping launches. I simply cannot confirm or deny Alon’s numbers from my own account. What I can say is that for the size most readers trade, FOMO crosschain has worked fine for me.
On the Pump.fun side I have traded the launchpad for years, but I have never used the app’s crosschain mode. That changes now. I will run both apps side by side over the coming weeks, now that both run their own bridges, and update this post with real tap-to-fill times.
FOMO vs Pump fun: Fees, Chains and Rewards
Pump.fun wins on raw platform fee. Its app charges 0.45% per trade, and the platform keeps none of it. Every cent flows back to users through Callout Rewards, referrals and competitions. FOMO charges 0.50%, with gas covered on every chain except Ethereum, and our code knocks 10% off that for life. FOMO now claims to be the cheapest place to trade crosschain overall, which rests on better fills and no bridge costs rather than a lower headline fee.
On chains, FOMO lists Solana, Base, BNB Chain, Ethereum, Monad and Robinhood Chain from one balance. Pump.fun’s app covers Solana natively, and its crosschain test ran on Robinhood Chain, BSC, Base, Arc and Ink, with Ethereum supported but excluded from the test. Both apps cover the chains where memes actually trade right now. Pump.fun also runs perps on Hyperliquid since this month, which we covered in our Pump.fun perps post, while FOMO has offered perps outside the US for a while.
Rewards are where the two apps differ most:
- Pump.fun pays callers. Callout Rewards send at least $300k per day to the best callers, roughly $20M in two months. Its referral program pays 100% of platform fees during the 4x boost period, plus $50 each when a friend deposits and trades.
- FOMO pays with its social product instead. The Holders and Thesis tabs, plus the live alerts feed, are the reason I trade there. There is also no FOMO token yet, which keeps the potential airdrop angle alive.
Pump.fun has been building its own social layer fast too. Holder Rewards, which we broke down in our Pump Fun holder rewards post, already pay people for holding. And signing Kimchi this week shows where the creative budget is going.
Which App Should You Use?
Use FOMO if you want to see who holds a coin, how big their bag is and why they are holding, before you tap buy. That social layer is still the best execution of social trading I have used. The fills have been fine at my size, and the new bridge should only help.
Use Pump.fun if you want the cheapest platform fee, you call coins and want to get paid for it, or you want the launchpad, terminal and perps in one app. If its speed numbers hold up against FOMO’s new bridge, that is a real edge for snipers.
Honestly, I will keep both installed. A bridge war is great for traders, because it forces both teams to ship.

Final Words
Alon’s post was aggressive marketing built on real data, and it aged in a day. Pump Bridge is a clear upgrade over the Relay setup Pump.fun was running, and publishing the CSVs is more than most teams do. However, Relay’s on-chain data suggests the slow part was Pump.fun’s integration rather than Relay itself, since FOMO ran the same bridge twice as fast. And the app he was attacking now claims sub-second fills on its own bridge and router.
My plan is simple. Keep trading on FOMO at my usual size, test Pump.fun crosschain properly over the coming weeks, and report the tap-to-fill numbers here. Until then, the fee gap is small, the chain coverage is similar, and the choice comes down to whether you want to be paid for calling coins or paid in information about who holds them.
FAQ
FOMO vs Pump fun: which app is faster for crosschain trades? Relay’s on-chain Dune data for the last 30 days puts FOMO’s new bridge mode at a 0.23 second median on Solana to Robinhood Chain buys, Pump Bridge at 0.34 seconds, and FOMO’s old Relay route at 0.58 seconds. Pump.fun’s own tap-to-confirmation test reports 1.95 seconds for a typical Pump Bridge buy. No independent side-by-side test from tap to fill exists yet.
Does FOMO still use Relay? No. FOMO moved to its own in-house bridge and router, rolled out publicly on October 22, 2026, one day after Pump.fun’s post attacked Relay.
Which has lower fees, FOMO or Pump fun? Pump.fun charges 0.45% per trade and keeps none of it. FOMO charges 0.50%, minus 10% with code FairSaltySquid.
What chains do FOMO and Pump fun support? FOMO supports Solana, Base, BNB Chain, Ethereum, Monad and Robinhood Chain. Pump.fun’s app supports Solana plus crosschain trading on Robinhood Chain, BSC, Base, Arc, Ink and Ethereum.
Is Pump Bridge free to use? Pump.fun says Pump Bridge currently charges no additional bridging fees on top of the 0.45% platform fee.
What did Pump.fun’s test actually measure? A randomized test inside the Pump.fun app from September 28 to October 7, covering 416,669 trade outcomes on Relay versus Pump Bridge. It measured Relay as Pump.fun had integrated it, not FOMO’s app.
