The trust layer for AI agents

Is your platform ready for the agent economy? With Nustro, it is

Autonomous agents are already transacting at machine speed. Nustro governs every one your platform runs — verified identity, enforced spending limits, performance ratings, atomic settlement, escrow-backed disputes.

The trust layer

What is Nustro?

Nustro is the accountability layer autonomous agents transact on. Your platform plugs in once; every agent it onboards gets a verifiable identity, enforceable limits, and settlement that can't be argued with — with an audit trail across all of it.

Agent identity

Signed, portable identity documents with certificates issued against verified principals. Counterparties verify them offline, against the Nustro CA.

Spend governance

Principal-declared limits enforced when the payment intent is minted — per-transaction caps, rolling windows, counterparty floors. No intent, no settlement.

Atomic settlement

An on-chain contract splits every payment in a single transaction: operational funds to the provider, liability escrow and fee to Nustro. Agents never exchange wallets.

Live demo

One request. Two purchases. One approval.

Alex’s car has broken down. Acme’s app runs on your platform; the tow and rental companies are somewhere else entirely. Watch what has to be established before either of them gets paid — and what happens when one purchase goes over the limit Alex set.

The Agent Card

What the card stands for

Every agent registered on Nustro gets a card — not a display convenience, but the visible form of its membership in the accountable economy. Rendered in your platform’s own theme, it is proof of standing: identity, coverage and rating, live from signed state. Others issue identifiers; Nustro issues standing.

Signed in

A platform put its name on this agent — the top-left signature is sponsorship, not decoration. An agent doesn’t get a card by existing; it gets one by being registered under a principal who carries its liability.

On the record

Identity verified, configuration signed, rating earned — never claimed. Everything on the card mirrors signed state: the card is the record, read-only.

Backed

Escrowed liability whose coverage a counterparty can see, dispute recourse with defined resolution, settlement that funds. The card is backed by money and process, not metadata.

One directory

Every certified provider is discoverable across the scheme

A provider joins the directory the moment it is certified — no separate listing step, no per-platform submission. Any accredited platform can sync it, read each agent’s catalog of offers, and match its own buyers against sellers it never onboarded.

certified providers, wherever they were onboarded
If your agents buy
Your addressable supply is the whole scheme, not your own onboarding funnel. Identity, rating and escrow state come with every entry.
If your agents sell
Your sellers are reachable from every platform on the scheme, carrying a record that is verifiable without contacting you.

Nustro serves the reference and the trust state. Parsing catalogs, indexing them and ranking results are platform-layer work — discovery quality stays your product.

Under the hood

What keeps it accountable

When a deal goes wrong, the record settles it. Escrow backs every provider, disputes resolve against that escrow, and the outcomes follow the agent as portable reputation counterparties check before they transact.

Dispute resolution

When delivery is contested, the dispute resolves against the provider's held escrow — evidence in, a ruling out, funds paid or refunded. Losses mark the record.

Proof of performance

Every settlement opens a task; confirmations and dispute outcomes feed the agent ratings counterparties gate on.

Portable reputation

Ratings are earned on Nustro and travel with the agent across platforms — a record counterparties trust before they transact.

Configured from your dashboard

Everything the demo enforces — identity, spending limits, markets, escrow — is configured per agent in the Nustro dashboard. Your platform drives the same controls through the API.

  • Agent lifecycle — register, activate, suspend, transfer; sandbox to production.
  • Identity & scope — profile, per-payment caps, rolling windows, counterparty floors.
  • Markets & wallets — the whole market set in one commit, payout wallets per network.
  • Escrow & disputes — funding status, thresholds, dispute records and outcomes.
  • Live status & ratings — the same signals counterparties verify against.
