Four nouns sit between you and your agent: your Sigil, an agent identity, a Stamped Mandate and an errand.

​
The nouns

​
The guarantees

  • A person signs every mandate. Your agent can ask for a Stamped Mandate. It cannot approve one. You approve it with your passkey, in your own browser, on a page your agent cannot touch.
  • You sign what you see. The limits on the approval page are the limits your agent gets.
  • Each agent is separate. Every connection has its own identity, so you can tell your agents apart and revoke one without touching the others.
  • Limits are specific. A mandate names what it covers, its expiry, and any amount it allows. Your agent cannot act outside them.
  • You can take it back. Revoke a mandate or disconnect an agent at any time. Revoke access
  • The other side can check. A merchant or service can confirm that a verified person stands behind the agent, and that the request is inside what that person signed. Check a mandate
