Fixed amounts are waived entirely and the whole charge becomes a flat rate — 0.40% Nustro, 0.10% each side. A nine-cent API call is charged a fraction of a cent, not a flat fee.

Access
Billed monthly on your statementScheme access
Production access, priced on how many agents you actually run. The count is the high-water mark of agents holding live certificates during the month — tiers are flat, not marginal. Waived in full for the founding cohort against committed volume.

Never charged, on any planSandbox
The complete flow on test networks — principals, agents, settlements, disputes. Self-serve, no payment method, no time limit.
Agents you have not launched
Draft and sandbox agents never count toward your tier. Building, testing and staging cost nothing.
Verifying anyone
Checking an agent’s certificate, status and rating is free for every party at any volume. Trust that costs money to check is not trust.
Escrow balances
No custody or holding charge. Escrow belongs to the seller’s principal and is never a source of fees.
Disputes
Filing, defending and deciding. The scheme charges nothing, and the party filing never pays.
Getting accredited
Business verification, review and going live carry no fee.
How it is collected
Taken from the transaction, not billed to youAt settlement
The settlement contract splits each payment in one on-chain transaction — the seller’s proceeds, its escrow contribution where one applies, and the fee. Nothing passes through a Nustro wallet, and nothing is ever taken from escrow.

Monthly statement
The statement is the record: it recomputes every fee, credits your shares, reconciles against what was collected at settlement, and nets to a single payable or receivable.
If a statement goes unpaid
Certificates are suspended on a published ladder — notice, then new issuance, then live certificates, then termination. Enforcement acts on credentials, never on wallets, funds or escrow.
What we commit to. Three prices only — what Nustro keeps and the two credits to platforms; what you charge your own principals is yours. Increases take effect no sooner than ninety days after notice, published with the reasoning; decreases can be immediate. No fee, discount or surcharge keys to an agent’s rating. Disputes are never a profit centre. The same schedule applies to every accredited platform — waivers are programs with published criteria, not private deals.
