How we score wallets
Every wallets we review is scored on the same 5 pillars, with the weights below. The overall score is a weighted average, same math we use for every silo.
By Skrumble EditorialLast revised Re-tested every 6 months, sooner after major firmware or app releases
Security
40% weight- Custody model (self / MPC / custodial) and key isolation
- Open-source code or vendor audit history
- Connectivity attack surface (USB / Bluetooth / air-gapped)
- Historical incidents and their resolution
Chain & Asset Support
20% weight- Number of supported chains and tokens
- Native asset coverage (BTC, ETH, SOL, plus EVM L2s)
- NFT support (where applicable)
- dApp / WalletConnect integration breadth
Ease of Use
20% weight- Time to first receive after install
- Mobile / desktop / extension UX parity
- Companion app polish and update cadence
- Recovery flow clarity
Cost
10% weight- Hardware price (for devices)
- In-wallet swap fees vs market mid
- Free vs paid feature tiers
Trust & Transparency
10% weight- Vendor transparency on incidents
- Public audit cadence
- Optional services (recovery, custody) — opt-in or default
- Privacy posture
— How we test —
We buy each hardware wallet at retail, install fresh, and run a fixed test set: receive on three chains (BTC, ETH, SOL), send to a known destination, install one third-party app, and attempt a recovery from seed phrase. For software wallets we install on a fresh device, run the same chain set, and verify dApp connection on three popular sites. Every score reflects the test, not the marketing.
— How the overall score is calculated —
overall = security * 0.40
+ chain_asset_support * 0.20
+ ease_of_use * 0.20
+ cost * 0.10
+ trust_transparency * 0.10Result is rounded to one decimal. We use a 0-5 scale because the human eye reads "4.2/5" more accurately than "8.4/10" or "84/100".
