OneKey vs Coldcard
Two hardware wallets with different architectures: Coldcard works air-gapped. Coldcard is Bitcoin-only (minimal attack surface), OneKey is multi-asset. On code, OneKey is fully open-source and auditable, the other is not: if sovereignty matters to you, that weighs a lot. On price OneKey wins: €79 vs €159. In our editorial rating OneKey leads (4.3 vs 3.6). Choose based on what you store: large, long-term holdings reward security, daily use rewards convenience.
