Pricing

One fee per transaction. Most of it goes back to the platforms.

A settled transaction carries a single scheme fee, split three ways: what Nustro keeps, what the platform on the paying side is credited, and what the platform on the receiving side is credited. Nothing else is charged per transaction.

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.

Effective rate falls as the transaction grows. Card-not-present typically runs 2.5–3%.

Access

Billed monthly on your statement
Scheme 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.

Free

Never charged, on any plan
Sandbox
The complete flow on test networks — principals, agents, settlements, disputes. Self-serve, no payment method, no time limit.
$0
Free
Agents you have not launched
Draft and sandbox agents never count toward your tier. Building, testing and staging cost nothing.
$0
Free
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.
$0
Free
Escrow balances
No custody or holding charge. Escrow belongs to the seller’s principal and is never a source of fees.
$0
Free
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 you
At 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.
on-chain
auditable per transaction
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.
15 days
net terms
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.

never funds
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.
