Seed XOR backups with the Coldcard wallet can allow for a more robust and physical duress-resistant setup. This effectively takes a regular wallet backup (which is vulnerable to anyone with physical access) and creates plausible deniability combined with complexity in recovery to prevent funds from being stolen.
This video walks through setting up a Seed XOR backup on the coldcard, full recovery, and how to utilize passphrases in concert with your backup.
