Blockstream Jade(@BlockstreamJade):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.
