 # Shared Improvements - Both Mk4 and Q
 
+- Huge new feature: CCC - ColdCard Cosign
+    - COLDCARD holds a key in a 2-of-3 multisig, in addition to the normal signing key it has.
+    - it applies a spending policy like an HSM:
+        - velocity and magnitude limits
+        - whitelisted destination addresses
+        - 2FA authentication using phone app ([RFC 6238](https://www.rfc-editor.org/rfc/rfc6238))
+    - but will sign its part of a transaction automatically if those condition are met, 
+      giving you 2 keys of the multisig and control over the funds
+    - spending policy can be exceed with help of the other co-signer (3rd key), when needed
+    - you cannot change the CCC spending policy (easily) once set.
