# BRL/USDC FX API for the CEO of a Cross-Border Fintech: A Last-Mile Settlement Rail in Brazil

> How the Crown FX API gives a cross-border fintech a BRL and USDC settlement rail for the last mile in Brazil, and under which regulatory status.

A cross-border fintech needs a rail that turns USDC into reais, and reais into USDC, at the end of the payment chain. The [Crown FX](https://crown-brlv.com) API covers that last mile: it converts BRL to USDC or USDT and back, settles in real time with Pix on the real side, and connects to traditional banking rails, including international dollar wires.

**What the rail includes**

- BRL or BRLV to USDC or USDT conversion, in both directions.
- Quotes and order execution through the API, at a price locked on confirmation.
- Reais in by Pix QR code; reais out by Pix, TED or token withdrawal.
- Per-customer sub-accounts under the partner model, so the fintech keeps its own brand.

**Regulatory position.** Under the FX-as-a-Service model, Crown handles the regulatory complexity and the mandatory Central Bank reporting, end-user transactions included. In September 2026 Crown had its authorization application on file as a virtual asset service provider and operated under the transition regime applying to every provider in the country.
