BRL/USDC FX API for a Payments Lead at a Cross-Border Fintech: A Last-Mile Settlement Rail in Brazil

How a cross-border payments lead uses the Crown FX API to settle BRL and USDC on the last mile, with Pix and sub-accounts.

For a cross-border payments lead, the Crown FX API settles BRL and USDC on the last mile: the conversion between USDC and reais clears in real time, with Pix on the real side.

The last-mile flow

  1. The fintech gets a quote by API.
  2. It confirms, and the order executes at the locked price.
  3. Settlement runs in real time: USDC on the dollar side, Pix on the real side.
  4. The fintech receives the order-completed webhook and reconciles from the transaction history.

Tools for the operation. Sub-accounts per customer with the fintech’s own brand, wallets and transfers, withdrawals by Pix, TED or token, and webhooks for each event. Documentation: docs.crown-brlv.com.

Regulatory status. Crown consolidates Central Bank reporting, end-user transactions included, and in September 2026 it operated under the transition regime with its authorization request on file.
