Why it leads
Why Nexus Mutual 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 (25.2 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 Nexus Mutual’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.

Facts
facts, not scoresWhat the record publishes
- Pricing
- Rates pulled live from api.nexusmutual.io/v2/capacity on 14 September 2026, not from marketing copy. Across the 233 listings with purchasable capacity (of 476 listed), the MEDIAN minimum annual rate is 2.00% of the cover amount; minimum rates run from 0.15% (Lido) to 29% (Mellow Finance Bug Bounty Cover). Dynamically priced listings rise 0.05% for every 1% of pool capacity used, while slashing and bespoke listings use fixed pricing, so the minimum is a floor, not a quote. Verified examples: Aave v3 0.88–2.60%/yr, Uniswap v3 0.20–0.82%, Curve All Pools 0.25–3.88%, Ether.fi Slashing 0.75%, Sky USDS Depeg 0.50–0.55%, BingX Custody 4.27%, HTX 3.96%, Hyperliquid Core 4.42–5.45%. Cover is denominated in ETH, USDC or cbBTC; the cover fee can be paid in ETH, USDC, cbBTC or NXM. Joining the mutual costs a one-time 0.0020 ETH membership fee.Nexus Mutual — verified source ↗ · 14 September 2026

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.
