Create a wallet with your own devices
Two keys come from your own signing devices, such as a Coldcard, SeedSigner or Jade. SovereignKey adds the Backup Key as the third. Each device shows or saves only its public multisig key (BIP48, native segwit); nothing private leaves it. Any two of the three keys can spend.
On the device, export the multisig key: Coldcard: Settings → Multisig Wallets → Export XPUB. SeedSigner: Scan a seed → Export Xpub → Multisig → Native Segwit.
Device 1
No key yet.
Device 2
No key yet.
Third key
SovereignKey Backup Key, held offline in our vault. It signs only when you ask, within 2 business days.
Each wallet is $5 a month; creating one needs a wallet slot under Billing.
Your wallet is ready
Load its configuration file onto both devices (Coldcard: copy it to the microSD card, then Settings → Multisig Wallets → Import from File). Check the device shows the same keys, then sign one small test transaction with each before you rely on it.
