Are Unchained keys held by a third party to custody bitcoin assets?
No. Unchained custodies our own key. Our partner key agents manage their own keys separately.
How we custody our key:
Our multisig vaults and commercial loans utilize Unchained as a key signer. These backup keys are protected by our in-house security model and are geographically distributed. While we can't reveal specific details, know that a third party never holds our keys.
Our partnership with Fortis Bank for commercial loans
Unchained commercial loans utilize one key from you, one Unchained key, and a key from our partner Fortis Bank. The Fortis Bank key is managed separately. Fortis signs transactions if Unchained is unavailable or if loan terms are breached.
