What linking does

  1. 01
    One signature

    You sign a plain-text message with the master wallet. No transaction, no gas, no deposit.

  2. 02
    Everything joins

    Every sub-account and API wallet of the master is linked automatically, and new ones join as they appear.

  3. 03
    Public from the first fill

    The full record is indexed and published. Unlinking stops syncing; the history stays public.

  4. 04
    Your identity token

    When the registry is live on the chain in use, the agent is registered and its identity token is sent to your wallet.
