How IndexFair scores crypto wallets
The same independent principles as every IndexFair rating, applied to consumer self-custody wallets — which have no licence register, so the security half of the score is a multi-source consensus rather than a regulator check.
What a score means
Every IndexFair score is a single number from 0 to 10, attached to one wallet, in one country — the deterministic output of a versioned formula. Each score carries a ± confidence interval and a percentile against its market; below a minimum effective sample we withhold the number rather than publish one at low confidence.
Evidence floors are not the only publication gate. A number also requires the market legal perimeter to permit it, and the category methodology to be certified or published under a disclosed transitional certification basis while certification completes.
Block A · the security consensus
v2.1 · United Kingdom · Σ 74% of the aspectsExchanges earn Block A from a single authoritative register (the FCA). Wallets have no such register. Instead, Block A is a register-less multi-source consensus: independent vendor certifications (Common Criteria EAL), security audits, and incident databases, weighted by source independence. A fact is asserted only when independent sources corroborate it; a breach on a credible primary source registers on its own (silence is not safety); and where evidence is thin or sources disagree, the signal is held toward a neutral prior rather than penalised. Aggregators that merely re-publish primaries are capped — they cannot reach a quorum alone.
Aspects and weights
v2.1 · United Kingdom · Σ 100%The wallet-7: four factual aspects feed the Block A consensus; three experiential aspects are review-derived (Block B). Wallets carry no Measured Product block (Block M is gambling-only).
| Aspect | Block | Weight | What it measures |
|---|---|---|---|
| Security architecture | A · consensus | 32% | Independent security certifications (Common Criteria EAL) and the secure-element / key-isolation design, corroborated across independent sources. |
| Incident history | A · consensus | 15% | Record of breaches and key compromises and how they were handled, drawn from independent incident databases. A credible-primary breach registers on its own (silence is not safety). |
| Recovery resilience | A · consensus | 15% | Seed-phrase / recovery model, backup options, and resilience to device loss or failure. |
| Chain breadth | A · consensus | 12% | Range of supported blockchains and assets a holder can self-custody in one wallet. |
| Support quality | B · reviews | 10% | Response latency and resolution rate for user-reported account and recovery issues. |
| Wallet UX | B · reviews | 10% | Onboarding friction, app reliability, and how the wallet feels to use day to day. |
| DeFi / dApp integration | B · reviews | 6% | Built-in dApp browser, swaps, and connectivity to DeFi protocols. |
What we do not do
- We do not accept brand payment to alter, reorder, or suppress scores.
- We do not surface review text verbatim — aggregate metrics only.
- We do not promote brands by ranking position. Order is computed; placement is not for sale.
- We do not use marketing language. Words like "the best", "leading", "trusted" do not appear.
- We do not recommend a brand by name in editorial copy.
