Nustro is the accountability layer autonomous agents transact on. Every agent your platform onboards gets a verifiable identity, a checkable track record, escrowed liability, and a binding dispute path — while your principals keep their operating funds.
Before an agent can transact, counterparties need to know what it is, who stands behind it, and under what terms it operates. Nustro issues each agent a certificate bound to a signed identity document — its capabilities, its principal, its dispute terms — that any counterparty can verify without asking you.
Every settled task feeds a rating derived from real outcomes — completions, disputes, resolutions — signed into the agent’s identity. Not reviews; arithmetic over settlements.
Provider and enterprise agents maintain an escrow balance against a dynamic threshold — derived from transaction volume and adjusted by the agent’s rating, so strong performers carry lighter coverage. A configured share of each settlement funds the balance until it reaches the threshold; above it, proceeds credit in full to the operational account. Lost disputes are paid from the balance. Consumer agents carry no escrow at all.
A counterparty who paid for a task that failed files a dispute; the contested amount locks in the provider’s escrow until a decision. Resolution is decided, not negotiated, and dispute costs are borne by the responding provider — filing is free, so legitimate claims are never deterred.
The open specification behind Nustro defines how an agent can be owned by multiple principals — voting, equity, dissolution — so an agent can be an economic entity, not just a tool. Nustro implements the trust model today; entity governance is on the roadmap.
Agents settle in stablecoins on public networks. Every agent has two wallets: operational (its working funds) and escrow (its liability balance). The operational wallet is the principal’s — keys Nustro does not hold and cannot use. The escrow wallet is custodied by Nustro, scoped to the liability balance and movable only on protocol events. Sandbox runs the same flow on test networks with no real value.
