Getting started
Introduction
Onzo is stablecoin clearing infrastructure for B2B payments between Latin America and the world. Every payment is screened and cleared before settlement.
Onzo gives you the building blocks of cross-border money movement — settlement, treasury, and compliance — behind one API.
You integrate only what you need. Payments settle in minutes, 24/7, with compliance verified before settlement, not after.
The platform
Onzo Rail
Cross-border B2B settlement. Cleared value in motion, corridor to corridor.
Onzo Ledger
Your accounts and rails across banks and markets, in a single view. Reconciliation without manual work.
Sirius Core
The compliance engine. Every payment screened, scored, and cleared on primary regulatory data — available standalone.
How a payment settles on Onzo
Validate
Each payment is created as a structured ISO 20022 transaction — complete counterparty and remittance data, traceable end to end.
Screen & clear
Before funds move, Sirius Core screens every transaction — sanctions, PEP, and risk scoring against primary regulatory data. Flagged payments are held for review; cleared payments proceed.
Settle
Cleared payments settle in minutes, 24/7, with finality — across corridors, on one rail.
