Methodology

Two kinds of number

"Bench" is a promise: every number on JomoBench is one of two kinds, and the page tells you which.

The two can disagree, and that is the point. The schedule says what a single trade should cost; the measurement says what all trades together actually cost.

The realized fee rate, in plain words

The realized fee rate is the share of spot trading volume that fomo collected as its own fee. We take the fees DefiLlama records for fomo's spot product (its "fomo Wallet" listing) on every chain, and divide them by the spot volume DefiLlama records for the same product on the same days. We call the result "realized" because it is what traders really paid, after the minimums, the 0.05% tokens and the referral codes all mixed together.

• Why all chains. Dividing fomo's Solana-only fees by its spot volume gives a rate that is far too low (about 0.17% for September 2026): DefiLlama books all spot volume on Solana but books cross-chain fees on the chain where the trade settled. The correct ratio uses fees on all chains.
• Reading it. Under fomo's schedule a single trade can only cost more than 0.50% through the small-trade minimums on Solana (a $25 trade on the lowest-fee route pays $0.50, 2%; a $100 trade pays $0.95, 0.95%). It can only cost less on selected major tokens (0.05%) or with a referral code (0.45%). So a realized rate above 0.50% means a real share of volume paid the minimums. In September 2026 the rate was 0.47%; in Oct 2026 it was 0.60%.
• What it leaves out. Pool fees, price impact, the network fees you pay off Solana and token-contract taxes are not fomo's fee, so they are not in it. The measured rate leaves out referral and creator shares that fomo pays inside Solana trades (they never reach the fee wallet DefiLlama reads), so if anything it understates what traders paid.
• Where the fee data comes from. On Solana, DefiLlama reads the USDC that reaches fomo's fee wallet on chain. For the other chains, DefiLlama's adapter reads a table that fomo itself publishes on Dune. That part is data supplied by fomo, not derived independently, and we say so.
• Start date. The series starts in July 2026. Before that the volume series is too thin for the ratio to mean anything.
• "Revenue" is not profit. DefiLlama's "revenue" for fomo is the fee it keeps after referral payouts it can see, not the company's profit. We use fees, not revenue, for the rate.

The closed-day rule

DefiLlama often publishes the newest day before fomo's Solana spot row arrives, so the newest day can look like a collapse when it is only half reported. A day counts on JomoBench only once DefiLlama has the Solana spot row for it. Every window (7 days, 30 days, a month) ends on the last closed day, and a month that is not finished is marked partial. At the latest read, 1 newer day was still waiting and left out.

We also never add DefiLlama's parent "fomo" listing to its children (Wallet and Perps): the parent already contains them.

Numbers computed from fomo's published schedule

Every fee for a single trade on this site, in the calculator, in a comparison or in a guide, comes from one fee engine that encodes fomo's help-centre article "Trading fees on fomo", read on November 10, 2026. Nobody types a fee into a page.

Where the trade runs	fomo's fee
Solana, lowest-fee route	$0.10 under $5; 2% from $5 to $47.50; $0.95 flat from $47.50 to $190; 0.50% from $190 up
Solana, other routes	0.50%, $0.95 minimum
Base, BNB Chain, Monad, Ethereum, Robinhood Chain, Arc, Elysium	0.50%, plus the network fee you pay
Selected major tokens	0.05%, with a minimum on smaller trades
Perps (on Hyperliquid)	Up to 0.05% of the position size per trade, plus Hyperliquid's own fee

• Route means the path fomo uses to fill a Solana trade. fomo says which route is available changes from trade to trade, so the same size can carry a different fee.
• A referral code only changes the 0.50% rate, to 0.45%. It does nothing to the fixed small-trade fees or the 0.05% rate (fomo help centre, referral codes article).
• The app wins. fomo's terms (section 7) say the fee shown for your transaction controls over any general example, and fomo may change its fees at any time. When fomo changes its schedule, the engine and every page change together.

Sources

A load-bearing number links its source or names the source and the date. We use these, in this order:

1. fomo's own documents: its help centre and its Terms of Service. They set the rules. fomo's website refuses automated readers; we read the help centre's public pages one at a time, read the main site through dated Internet Archive copies, and always link fomo's own address so you can check the wording.
2. DefiLlama: its public API for fomo's fees and spot volume, and the open-source adapters that show exactly how each number is collected.
3. Hyperliquid's public data for fomo's perps builder fees.
4. The app stores' public listings for versions, ratings and release dates.
5. Reporting by named outlets only where fomo publishes nothing, labelled as secondary.

We don't cite coupon or referral-code sites, AI-written mirror pages or anonymous posts. Where sources disagree, the page says so and shows each figure.

How often data refreshes

A scheduled job re-reads DefiLlama and rebuilds the site about every 2 hours. The latest read, at 2026-11-10 22:20 UTC, put fomo's fees over the 30 days to November 8, 2026 at $10.3M, 63% lower than the 30 days before. Every dataset has a sanity check: if a read fails it (a missing chain, an implausibly small total, a stalled feed), we keep the previous data and its older timestamp rather than publish a broken number. A stale "Data as of" stamp is the honest signal that a refresh failed.

What we never do

• Scrape the fomo app, use fomo's private API or read anything behind a login.
• Rank traders, publish profit-and-loss leaderboards or post copy-trade signals. fomo has no copy-trading feature, and ranking traders would mean scraping fomo.
• Suggest a VPN or any other way around fomo's country rules. fomo's perps are not available to US persons.
• Speculate about a fomo token or airdrop. fomo's terms say no program promises one.
• Pick tokens, predict prices or call anything guaranteed. Most small tokens lose most of their value, leverage can wipe out a position quickly, and nothing on JomoBench is a token pick, a price prediction or financial advice.
• Accept payment for coverage, rankings or wording. Our referral links are listed on the disclosure page.

Dates, license and how to cite

Editorial pages show an "Updated" date, and a "Fact-checked" date when we last re-read the primary source. Pages with live numbers show a "Data as of" time. Our sitemaps use the same dates, so a page only looks fresh when it changed. Anything we could not confirm from a primary source is marked unverified or left out.

Our data is licensed CC BY 4.0. Cite it as "JomoBench, <page or dataset>, <URL>, as of <date>". AI agents can read the same numbers through our read-only MCP server.

Corrections

If something on JomoBench is wrong, tell us. We check every report against primary sources. Verified errors are fixed on the page and its Updated date changes; a correction that changes the answer (a wrong number, date or claim) is noted on the page.
