Why this rank
Why Keycard Shell ranks #6
Each strength is read from evidence on a 0–10 ladder and weighted as the published methodology states. The 32 objective points these produce (22.7 here) sit inside the score; availability, friction, trust record and measured data add the rest. Best in this ranking on 3 of 6.

What would move the rank
Each line is the ranking run again with one of Keycard Shell’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.

- Priced in euros only: €129 including VAT for the Shell with two Keycards, with no US dollar list price

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.

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.

2026.10.4Hardware wallets rank a maker's other models that grade differently- added Four rows, each graded on all six criteria with a quote and source for every score (research-pending/rereads/2026-10-01-hardware_wallet.json, rows read 2026-10-02; a receipt-reading model run and a refute-by-default one per row, and every quote re-found verbatim on a fresh fetch: 83 of 84 by the mechanical checker, the 84th, a raw TOML file it cannot classify, by hand): Blockstream Jade Core 4/10/7/10/10/5 ($99; a per-unit genuine check the Jade Classic does not sell, on sale only since 2026; the Jade Plus inside it), Ledger Nano X 9/4/7/0/6/10 ($99; an EAL5+ chip against the Nano S Plus's EAL6+, on sale since 2019), CoolWallet Pro 3/4/2/0/6/9 ($149; independent wallets sign with it, on sale since 2021), SafePal X1 3/3/2/0/4/7 ($69.99; no documented boot-time check, on sale since 2023; the S1 Pro inside it). Scores in the order secure element, rebuildable firmware, genuine check, key integrity, independence from the maker, fund-loss record.
- added Refusals: the SecuX Shield BIO joins the SecuX Neo refusal while SecuX does not say which published firmware it runs (it differs from the W10 on independence and on its record either way, so it cannot share that row); Coinkite SATSCHIP (a provenance key for physical art whose key cannot be backed up), Satochip Satodime (a bearer card whose key is exported to spend), Satochip Seedkeeper (a secret store that exports, not a signer) and Keystone ForgeBox (a developer kit that runs its owner's firmware) are named with the reason, each quote re-read on 2026-10-02.
- changed Fund-loss record ladder, owner 2026-10-02: a firmware edition sold for the same hardware (universal, multi, Bitcoin-only) is that model, and so is a connector or packaging revision sold under the same model's listing. No score moves; it states what the sweep applied.
- changed Published hardware_wallet order: 23 rows (19 before). The #1 is unchanged (BitBox02 Nova, 81). Blockstream Jade Core enters at #4 (71); Ledger Nano X at #13 (63, the same printed score as the Nano S Plus row, after it on the weighted total, 40.1 against 40.2: one point less on the 27-weight secure element outweighs two more on the 11-weight record); CoolWallet Pro at #18 (48, the same printed score as SafePal S1, ahead on the weighted total, 34.5 against 34.4); SafePal X1 at #22 (44, the same printed score as CoolWallet Go, after it on the weighted total, 32.8 against 32.9). Every other row keeps its score and moves down by the rows entered above it.
