Why this rank
Why CoW Swap ranks #3
Each strength is read from evidence on a 0–10 ladder and weighted as the published methodology states. The 32 objective points these produce (17.0 here) sit inside the score; availability, friction, trust record and measured data add the rest.

What would move the rank
Each line is the ranking run again with one of CoW Swap’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
- CoW Swap keeps 50% of any price improvement it wins for you, capped at 0.98% of volume, plus the 2 bps volume fee. On a trade with meaningful surplus that cap is far larger than the 0.3-0.8% a typical sandwich costs — the protection is real, but so is the protocol's cut of it. It also only covers trades routed through CoW, not your other transactions.

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.

- 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.
