What are Brazil Rails?

How Lerian connects your institution to Brazil’s payment rails — Pix, TED, and boletos — through partner providers and Lerian-owned BACEN connections.

Brazil Rails is where the Lerian platform meets Brazil’s payment system. Each rail — Pix, TED, Boletos & Bill Payment — is a regulated way to move money. The Central Bank of Brazil (BACEN) operates these rails, or market infrastructures do under its supervision. Lerian gives your institution production-ready access to them. You keep ownership of your ledger, your data, and your business logic.

How this section is organized

---

The documentation here follows a rail → connection structure. Each rail has its own section — Pix, TED, Boletos & Bill Payment, and the rails that Lerian reaches only through its own messaging. Inside a rail section, you see every way to connect to it.

• Rail-level pages cover concepts, domains, and best practices that hold no matter how you connect.
• Connection sections cover the integration specifics of one path: Lerian native messaging, or a partner interface such as JD or BTG.

Two ways to connect

---

Lerian connects institutions to Brazilian rails through two models:

1. Native messaging — Lerian-owned, non-intermediated connections to BACEN’s networks and the market infrastructures under its supervision. Lerian SPI carries Pix and covers the full SPI messaging contract. Lerian SPB carries TED and covers the full SPB messaging contract. Five more native rails handle deferred settlement, card settlement, file exchange, judicial asset orders, and payroll-deductible credit.
2. Partner interfaces — adapters that integrate the platform with third-party connectivity providers. Today these cover Pix through JD and BTG, TED through JD, and boletos and bill payment through BTG. Your integration with the Lerian platform stays the same. The adapter absorbs the provider’s specifics.

Both connection models preserve your ledger, accounts, and business logic. They do not require a particular ledger; the rail emits settlement facts for your ledger consumer. See Native messaging and partner interfaces for how the two compare.

What runs in production today

Pix runs in production through two interfaces. The JD interface connects your institution as a direct participant through a certified PSTI. The BTG interface connects you 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.
