ckbunker is a program that you run on a computer attached to a Coldcard hardware wallet.
ckbunker will setup and operate the Coldcard HSM mode, where it signs without a human having to physically interact with the device.
The Coldcard implements a complex set of spending rules, called a policy - which cannot be changed once HSM mode is started.
ckbunker gives the end user immense flexibility to interact with Bitcoin safely and securely.
