Nunchuk Platform Key

If auth or network setup is the blocker, use nunchuk-setup.

What is Platform Key

Platform key is an optional Nunchuk-managed signer that can participate in wallet policy enforcement. It is a secure HSM key managed by Nunchuk.

For multisig wallets, the Platform key can occupy one signer slot.

For Miniscript wallets, the Platform key can be attached to one or more named signer slots from the Miniscript template.

For example, in a 2-of-3 wallet with two user keys and one Platform key, each transaction still needs 2 signatures. That can be:

• the user's two own keys
• one user key and the Platform key

Whether the Platform key signs depends on the active policy.
