Your bitcoin should answer to you alone.

Most people carefully back up their multisig seeds…
and forget the part that actually lets them reconstruct the wallet.
Without the configuration (descriptor), those seeds are incomplete. Jade can register and store your multisig configs on-device (up to 8) and export them later via QR if you ever need to rebuild the wallet.

Jade has had Anti-Exfil since the beginning.
A compromised hardware wallet can slowly leak your private keys through the nonces in its signatures, even if the keys themselves were generated securely.
Anti-Exfil stops this by using sign-to-contract: Jade cryptographically commits its nonce to random data from your host computer, fully re-randomizing it so no key material can be smuggled out.
