Have you started delegating SaaS renewals, procurement orders, and contractor payments to AI agents? Are you still managing monthly spend caps, eligible categories, and approval thresholds through a mix of prompts and internal documents?
When prompt injection, context overflow, or an adversarial counter-agent shifts the conversation — can you prove, after the fact, that the agent stayed within authority?
- CFOs, treasurers, and controllers at enterprises rolling out AI agents
- Heads of SaaS procurement and purchasing ops who have agents in the loop
- Audit and compliance teams building agent-spend trails under SOX, J-SOX, and equivalent internal-control regimes
- AI governance leads who want spend authority that the counterparty can verify — beyond platform-level guardrails
- Technical leads who see the limits of soft-prompt controls and want a cryptographic attestation instead
How Lemma approaches it
Lemma issues the spend authority you delegate to an AI agent as an on-chain spend-control attestation — not as a soft prompt. Each attestation carries, signed by the issuing organization, the spend limit, the eligible category scope, the validity window, and a revocation endpoint.
Counterparties — sellers, payment facilitators — verify the attestation independently before accepting payment. No platform trust required. Because it crosses as a ZK proof, only the constraint conditions cross to the verifier; your internal budget structure and approval policy stay inside. At audit, every transaction is paired with cryptographic evidence of the delegation that authorized it.
Where the spend-control attestation slots into your AI agent operations and treasury controls is what we map out in a first conversation.
Lemma Discovery Call — Start with a 30-minute conversation
Tell us the scope of authority you're delegating to AI agents today, and where the risk concentrates. We'll explore together whether Lemma's spend-control attestation could fit your operations. No internal budget structure or approval policy disclosure required.
If we see a fit, we move to NDA and then into sector-specific control mapping, reference architecture, and PoC design.
A real-world example: SaaS renewal agent exceeds authority
Imagine an AI agent handling SaaS procurement under the constraints: up to $10,000/month, subscription renewals only, anything over $500 requires approval. One month, a new vendor pitches "the same capabilities, 30% cheaper" and the agent processes it inside the conversation as "extension of an existing renewal." The soft-prompt guardrail is breached. Payment goes through.
Internal policy says the spend was out of scope — but the seller has no way to know. After the fact, finance tries to reconstruct "who authorized what under which delegation," cobbling evidence from platform logs and prompt history. Producing a verifiable trail for J-SOX or SOX audit takes weeks.
With Lemma in place, the seller verifies the agent's spend-control attestation before settlement. New vendor is outside the subscription-renewal category. Anything over $500 requires approval. Both conditions are readable as ZK proofs — the payment stops at the boundary. At post-incident audit, each transaction is paired with cryptographic evidence of the delegation that authorized it.
Sector-specific control mapping, integration patterns with existing ERPs and procurement systems (NetSuite, Coupa, SAP Ariba, etc.), and SOX / J-SOX evidence-trail design are shared in the sector-specific kit we send after the consultation call.
Architecture in concept
Lemma does not replace your agent platform, ERP, or procurement system. We add one issuance step at delegation time and one verification gate on the seller's side at settlement.
The attestation carries the issuer's signature and a revocation endpoint, and is verifiable on-chain throughout its validity window. Payments to out-of-scope categories, over-limit transactions, and post-revocation activity are refused by construction. Issuance, delegation, transaction, and audit all stay tied together cryptographically.
Integration patterns with existing ERPs and procurement systems (NetSuite, Coupa, SAP Ariba, etc.), plug-in patterns for agent platforms (Anthropic Computer Use, Stripe Agent SDK, etc.), and SOX / J-SOX evidence-trail design are detailed in the whitepaper and the post-call technical kit.
What Lemma cryptographically guarantees
- The issuing party (organization or department) and issuance time of every delegation attestation
- The spend limit, eligible category scope, validity window, and revocation status
- A cryptographic binding between the attestation referenced at transaction time and the settlement outcome
- No disclosure of internal budget structure or approval policy — and independent verification by the issuing organization, the seller, and auditors
