- Offer Import. If it's a new multisig wallet, offer to import \
the details and store them as a new wallet in the Coldcard.
- Trust PSBT. Use the wallet data in the PSBT as a temporary,
multisig wallet, and do not import it. This permits some \
deniability and additional privacy.
When the XPUB data is not provided in the PSBT, regardless of the above, \
we require the appropriate multisig wallet to already exist \
