What are Brazil Rails?

Brazil Rails is where the Lerian platform meets Brazil’s payment system. Each rail — Pix, TED, Boletos & Bill Payment — is a regulated way of moving money, operated by the Central Bank of Brazil (BACEN) or by market infrastructures under its supervision. Lerian gives your institution production-ready access to these rails without giving up ownership of your ledger, your data, or your business logic.

How this section is organized

---

The documentation here follows a rail → provider structure. The rail defines the domain — what Pix is, how TED transfer types work, what a boleto lifecycle looks like. The provider defines the connection — how your institution actually reaches that rail.

• Rail-level pages cover concepts, domains, and best practices that hold no matter how you connect.
• Provider sections (such as Direct via JD or Indirect via BTG) cover the integration specifics of one connectivity path.

​

Two integration layers

---

Lerian connects institutions to Brazilian rails through two layers:

1. Native messaging — Lerian-owned, non-intermediated connections to BACEN’s networks and the market infrastructures under its supervision. This layer spans seven rails, from Pix and TED settlement to file exchange and judicial asset orders. See Native Messaging for the full family.
2. Partner interfaces — adapters that integrate the platform with third-party connectivity providers. Today these cover Pix through JD and BTG, and TED through JD. Your integration with the Lerian platform stays the same; the adapter absorbs the provider’s specifics.

Payment traffic on both layers settles through Midaz — same ledger, same accounts, same business logic — so the connection model never changes how you record money.

​

What runs in production today

Pix runs in production through the JD interface — connecting as a direct participant via a certified PSTI — and through BTG as an indirect participant. TED runs through JD. The native Lerian rails are Lerian-owned software for a direct, non-intermediated connection to BACEN; they do not replace the JD and BTG paths.
