How We Verify Figures

The problem: fomo's fee schedule keeps moving

Until recently the problem here was a contradiction. fomo's Terms of Use stated, with no order-size qualifier: “We charge a minimum fee of 0.50% per transaction (subject to a minimum fee of $0.95 per transaction),” while its help center scoped a different and smaller minimum to Solana alone. We quoted both rather than ruling on which governed, because that is a contract question a guide has no business answering.

That contradiction is closed. fomo rewrote its Terms on 2026-08-17, and section 7 now names no fee figure outside perps. It says the fee “depends on factors including the size and type of the transaction, the token involved, and how the transaction is routed,” that it “is displayed before you confirm the transaction,” and that fomo “may modify its fees at any time in its sole discretion.” One authority, clearly named.

What replaced the contradiction is a harder problem for a reference site. The schedule itself moves: fomo published three different Solana schedules between 2026-08-08 and 2026-08-20, none a rounding of the others, with no announcement we could find. So the rule here is that we re-read the source rather than carrying a figure forward, every fee on this site carries the date it was read, and no page claims a rate is current beyond that date. When a figure changes we say what it was before and when it changed, because a reader who acted on the old number deserves to know it moved. More on how that shaped the site on the about page.

The three evidence tiers

Every factual claim on this site traces to one of three tiers, and pages label which one they're leaning on whenever it matters.

Below those three sit dated press reports, used for corporate events like funding rounds where no primary source is public, always attributed and always flagged as reported rather than established. We do not publish claims about a third party's ownership, funding or acquisitions unless we can point at a dated source in the same sentence. Reddit, X and App Store reviews are quoted only as evidence that a user problem exists, never as evidence that a number is correct.

Baseline figures we hold to source

These are the numbers every fee, referral and comparison claim on the site is checked against, last read on 2026-08-14. Where a row quotes fomo, the quotation marks are literal.

The fee calculator encodes exactly these figures and nothing else.

Claims we refuse to publish

Every one of these circulates widely, and some appear on sites that rank above us. Each is excluded for a specific reason, not a stylistic one.

Where a claim is merely unverified rather than false, we say “unverified” on the page instead of dropping it silently or guessing.

Market data

The market pages pull prices, liquidity and volume from GeckoTerminal and DefiLlama rather than from fomo itself, since fomo has no public market-data API. Those figures move constantly and are presented as live data, not as verified editorial claims. Treat them as a snapshot and confirm anything you're about to size a position on.

The Solana Trading Cost Index

The cost index is published monthly and has two layers, which are kept separate on purpose. The measured layer is a live Jupiter quote per token per order size, recording the price impact and the exact route taken, plus the SOL price and a sample of recent Solana priority fees. The modeled layer is each platform's published fee schedule, applied to that quote. Adding them gives a comparable all-in cost with execution held constant.

Holding execution constant is what makes the six platforms comparable, and it is also the index's main limitation. Jupiter is the only one of the six that documents its own router. BullX, Photon, Axiom and GMGN do not publish what performs their swap routing, so a platform routing better than Jupiter beats these numbers and one routing worse misses them. Nothing in the index is an executed trade.

fomo appears at its standard published rate, never at the referral rate this site earns from. An index that quoted our own discount would be an advertisement rather than a measurement.

The first edition, the cost readings this methodology produces, is the worked example: the same six platforms, four order sizes, and the measured and modeled layers reported separately so you can see which half of each number we observed and which half we applied.

Every edition's raw JSON is published at a permanent URL alongside it, and published numbers are never edited. A build-time checksum on each edition file fails the build if a published edition changes, so a correction has to be a visible changelog entry rather than a silent rewrite. None of the five competitor fee pages carries a last-updated date, so each schedule records the date we read it, which is the only claim the sources support.

Review cadence

Every guide carries a Last Updated date in the byline. Pages built on figures that move (fees, the referral rate, chain coverage) also carry a Last Verified date recording the last manual check against fomo's Terms and help center.

Fee and referral pages are re-checked at least monthly, since a documented discrepancy like the fee-minimum one means a future fomo update could resolve it in either direction. Comparison and ecosystem pages are re-checked quarterly or when something material happens, such as a new funding round or a feature launch.

Limitations

Fee figures pulled from DefiLlama, like the realized 1.587% take rate on fomo's 30-day Solana volume, are our arithmetic on a third party's data rather than a fomo policy. We label them that way and show the working instead of presenting them as an official number.

Press coverage of funding rounds is secondhand and sometimes disagrees with itself on dates or amounts, in which case we give the range instead of picking a winner. Anything we say about another company's ownership, funding or corporate history is reported, not verified by us. This space moves fast enough that a figure checked today can be stale next month, so when accuracy matters for a decision you are about to make, follow the source link on the page.

Reporting something wrong

If a figure here looks out of date or wrong, tell us. The fastest route is a direct message to @Concept211 on X or an email via the contact page. Include the URL, the figure, and the source you're comparing against. Corrections are prioritized over new content.

Editorial independence and disclosure

FomoAppGuide earns from referral and affiliate links, set out in full on the about page. That does not decide which figures get published or how a comparison lands. The banded pricing on small Solana orders, which makes a $10 trade an effective 2% and a $50 trade 1.90%, is the least flattering thing on this site, and it is also the page we put the most work into: fomo Fees Explained. Where fomo's marketing describes a feature we cannot find documented as live, copy trading being the obvious one, that gets covered too.
