Why it leads
Why Karnot ranks #1
Each strength is read from evidence on a 0–10 ladder and weighted as the published methodology states. The 32 objective points these produce (20.2 here) sit inside the score; availability, friction, trust record and measured data add the rest. Best in this ranking on 2 of 4.

What would move the rank
Each line is the ranking run again with one of Karnot’s criterion scores changed and every other value held: the smallest whole-point change on that criterion that moves its rank, and where the re-run puts it. Up to 4 climbs and 3 falls are listed, smallest change first. Nothing here is a forecast.

Record watch-outs
- Karnot is the only vendor that tells you the price before the call — $5,000/month, above the $3,000/month implied by Conduit's own blog — but it is Starknet-only, has exactly one chain L2BEAT tracks, publishes no uptime measurement or status page, and makes no written commitment to hand you the keys. You are buying price transparency and clean on-chain custody on a sample of one, and taking the operating record on faith.
Competitive position
How Karnot places on each criterion
Rank on every objective dimension among the rows scored on it. A criterion in the top third of its pool is listed as a lead, the bottom third as a trail; the middle is neither. Popularity, size and commercial terms are not dimensions.

Facts
facts, not scoresWhat the record publishes
- Pricing
- karnot.xyz (re-fetched 25 September 2026, HTTP 200; karnot.xyz/pricing returns HTTP 404, so the price lives on the homepage), pricing section, quoted exactly. DEVNET AND TESTNETS: "Free" / "For the tinkerers" — "Sequencer Explorer Bridge Faucet Dashboard". MAINNET: "$5000" "/ month" / "For growing teams" — "EVERYTHING IN TESTNET, PLUS: Automatic upgrades High uptime Detailed monitoring On call support Customisations". Normalised on 2026-09-25: 5,000 a month x 12 = 60,000 a year in US dollars, all-in for the listed components, with no revenue share attached. The only other vendor-stated mainnet figure in this pool is on a different vendor's blog — conduit.xyz/blog/rollup-total-cost-of-operations-tco (re-fetched 25 September 2026, HTTP 200) still states a cost of thirty-six thousand dollars per year to run a rollup on mainnet plus onchain DA costs, i.e. 3,000 a month — and that figure is contradicted by Conduit's own pricing page, which quotes every mainnet chain tier as Contact for pricing plus five percent of sequencer profit. Karnot's 5,000 a month therefore remains the only mainnet monthly price in this pool published on the page where you would buy it. Both figures were re-fetched on the same day, 25 September 2026, so the comparison is same-date.Karnot — official pricing page ↗ · 25 September 2026

History
What the record carries
Changes to published ranks are recorded in a ledger; every step and its cause is listed on the rank-history page. The entries below begin with the current verified snapshot, then the methodology versions whose changes applied to this category, newest first.
9 methodology entries
- 25 September 2026Current verified snapshot · methodology 2026.11.1Score 79, #1 of 8. 4 of 4 criteria scored. History starts here; earlier values are not interpolated.
- 10 October 2026
2026.10.8When nothing serves your country, the list shown for reference is the published ranking · platform-wide- fixed The reference list shown when nothing serves your country is the published order with the published scores, and a build check now fails any such list out of that order or with a score the ranking does not publish.
- fixed The explorer prints an overall rank only for a row the published ranking holds; a country entrant such as Coinbase Commerce for US merchants shows no overall rank.
- changed Published orders do not move. Country results change only where nothing serves the country: in India bill pay keeps Bitcoin Well first and now shows Strike second, as published; 35 such runs across all categories and countries now match the published list exactly.
- 10 October 2026
2026.10.6A criterion you require re-scores the rows that meet it · platform-wide- changed The explorer sends each criterion you require, at any band, as fit_required with your other answers; region, licence, chain and fact filters stay filters. On /best, a required criterion joins For you as a marked preference does, which needs your country; Overall stays the published ranking, filtered.
- added Every published criterion has a golden case as the explorer sends it (require:<criterion>), so the order a requirement gives is replayed and gated as the published order is, and a change to it needs an entry here.

2026.09.15Dimension scores carry tenths, and eleven more categories are re-read from primary sources · platform-wide- changed Dimension scores resolve to tenths of a point (O-04b), and weightedTotal is rounded to six decimal places before the order is read. 518 published scores move across 107 categories that were not re-read; none of them moves by more than 4 points, and most move by 1.
- fixed 66 published scores change in the eleven re-read categories, against a verbatim source each. The largest moves are Reflexer RAI (−16), Beefy and Unrekt (−11), Aztec (−10) and Golem (+9) — all of them rows whose sources had moved since their last read.
- changed Published order moves in 38 of 119 categories and three #1s change: smart_contract_audits (Zellic → Certora) and travel_rule_compliance (Sumsub Travel Rule → CodeVASP) on the finer resolution, kyc_compliance (Veriff → Sumsub) on the re-read.
- added availabilitySource (O-04g): for a reader who states a country, a row whose availability in that country rests on a region tag its record gives no source for sorts below every sourced row. It is inert in every order published here, which states no country.
