Noxpay as a Service (NaaS) lets platforms, ERPs, and software houses embed PIX-to-stablecoin payment capabilities directly into their products — under their own brand, with their own revenue model, running on Noxpay’s infrastructure. You own the merchant relationship. We handle the infrastructure, compliance, and KYB.

​
The opportunity

Your merchant base is already moving money — paying suppliers, receiving customer payments, managing cross-border flows. NaaS lets you become the financial layer they operate through, without having to build payment infrastructure or own compliance. One API integration unlocks the full stack for your entire platform.

​
How it works

1

Integrate once

Connect to Noxpay via the NaaS API. A single integration gives your platform access to the full infrastructure.
2

Onboard your merchants

Create sub-merchants under your master account. Each merchant operates independently with their own identity, KYB flow, and balance — all under your brand.
3

Your merchants transact

Sub-merchants accept PIX payments, receive stablecoins, and manage withdrawals — all flowing through your branded experience.
4

You earn on volume

Configure a revenue split for every transaction processed through your platform. You decide the split percentage per merchant.

​
Key features

Once approved, you will receive your master API key and public key registration instructions. From there, everything is done via the NaaS API.
