§ 01 — Use Cases
Where a mandate becomes
the record.
An Agent Mandate records who authorized an agent, in what scope, under which law. Readable as prose, executable as code, revocable on record. Four scenarios show how companies use Ambr, the Agent Mandate & Binding Registry, to authorize AI agents, let them act under recorded mandates, and hold an accountability record for every action.
§ 02 — In practice
Authority and its exercise, on record.
Each mandate names a principal, a scope, and a counterparty. It is minted as a single cNFT on Base L2, with its SHA-256 hash stored permanently on-chain.
Agent Delegation Authorization
A logistics company authorizes its AI procurement agent to purchase supplies up to $5,000/month. The Delegation Contract specifies spending caps, approved vendor categories, and liability terms — giving the agent verifiable, on-chain proof of authorization.
Parties
Contract Terms
Spending cap ($5,000/mo), approved categories (office supplies, shipping materials), excluded vendors list, liability terms
Outcome
Delegation Contract signed, cNFT minted to company + agent wallets, agent can prove authorization to any vendor
Integrations
Payments: x402 V2 payments on Base within authorized limits
Reputation: ERC-8004 identity registry verifies the agent's principal company
Contract: Ricardian Delegation Contract with Principal Declaration naming Acme Logistics as the authorizing entity
Agent-Executed Procurement
Under a recorded Delegation mandate with a $2,400/mo cap, a company's agent negotiates and purchases cloud compute from a vendor. Ambr generates the dual-format mandate — human-readable for the vendor's legal team, machine-parsable JSON for the agent — with payment flowing via x402 V2.
Parties
Contract Terms
GPU allocation (A100 x4), 99.9% uptime SLA, $2,400/mo pricing, 90-day term, auto-renewal clause
Outcome
Mandate signed by the agent on behalf of TechCorp — within its recorded authority — cNFT minted, vendor legal team can review via Reader Portal
Integrations
Payments: x402 V2 session-based billing with Nevermined metering
Reputation: ERC-8004 reputation check on vendor before contract signing
Contract: Dual-format Ricardian Contract — legal text for vendor counsel, structured JSON for agent enforcement
Agent-Signed Service Agreement
Acting under its agency's recorded delegation authority, an AI agent negotiates and signs a SaaS analytics agreement on the agency's behalf. The mandate records data handling terms, SLA guarantees, and an IETF ADP dispute resolution clause — every commitment traceable to the authority that permitted it.
Parties
Contract Terms
Enterprise tier access, data retention (12 months), GDPR compliance clause, 99.5% uptime SLA, $499/mo
Outcome
Service agreement signed at machine speed, cNFT as proof of agreement, amendment chain for future upgrades

Contract: Ricardian Contract with IETF ADP dispute resolution, Principal Declaration naming BrightStar Agency
Compliance Audit Trail
An enterprise legal team needs to review all contracts their AI agents have executed over the past quarter. Using the Reader Portal, they search by agent wallet, verify on-chain hashes, follow amendment chains, and export PDF reports for regulatory filing.
Parties
Contract Terms
Every mandate the company's agents executed in Q1 2026, including amendments and extensions
Outcome
Full audit trail via Reader Portal — view, verify, print any contract by hash or cNFT ID, follow amendment chains
Integrations
Payments: Payment records linked to each contract via x402 V2 transaction metadata
Reputation: ERC-8004 identity verification confirms which agents acted on behalf of the company
Contract: Immutable cNFT records with parent_contract_hash linking originals to amendments and extensions
§ 03 — The through-line
Every scenario resolves to a liability record.
Whether an agent buys supplies, procures compute, signs a service agreement, or fills a quarter of audit history, the same artifact carries the weight: an Agent Mandate that names the authorizing entity, its scope, and the governing law. Human-readable, machine-parsable, minted as a single cNFT on Base L2, revocable on record.
