FAQs
Why use multisig for €1M+ holdings?
Multisig (e.g., 2-of-3 with different hardware vendors) eliminates single-point-of-failure: if any one device is compromised or any one vendor backdoored, your funds remain secure. For high-value holdings the small operational overhead is worth the dramatically reduced risk.
Are these hardware wallets MiCA-licensed?
No — hardware wallets are non-custodial products outside MiCA scope. See /mica/check/ledger and /mica/check/trezor for the detailed rationale.
How do I distribute seed shares for multisig?
For Bitcoin multisig, the seed phrases of each hardware wallet should be stored in separate, geographically-distant, fire-and-water-resistant locations. Common patterns: home safe + bank deposit box + trusted family member. Each location should be sufficient to reconstruct one share but never all of them.
