BTG Pactual is one of the largest investment banks in Latin America and operates as a direct participant in Brazil’s Pix ecosystem. Through its Banking as a Service (BaaS) infrastructure, BTG provides indirect participants with regulated connectivity to BACEN’s SPI (Instant Payment System) and DICT (Transactional Account Identifier Directory).

​
BTG’s role in the Pix ecosystem

As the direct participant, BTG handles the layers that require regulatory licensing and direct BACEN integration:
  • SPI connectivity — Sends and receives Pix payment messages (pacs.008, pacs.002, pacs.004) through BACEN’s real-time settlement infrastructure
  • DICT access — Manages Pix key lookups, registrations, and claim resolutions at the BACEN directory level
  • Settlement and liquidity — Processes financial settlement between institutions through BACEN’s infrastructure
  • Regulatory compliance — Maintains the certifications, audits, and operational requirements BACEN mandates for direct participants
  • Webhook notifications — Delivers real-time event callbacks for transaction status changes, key events, and dispute updates
  • mTLS security — Provides certificate-based authentication for secure webhook communication
Your institution retains full control of its ledger, customer data, business rules, and operational infrastructure. BTG provides connectivity — not account management.

​
Why BTG

BTG brings specific advantages as a direct participant for Pix operations:
  • Production-ready infrastructure — BTG already operates at scale in the Pix ecosystem, processing high volumes with proven reliability
  • Native integration with Lerian — The Indirect Pix Plugin includes built-in support for BTG’s APIs, authentication, and event model, eliminating custom middleware
  • Faster time to market — Institutions launch Pix in weeks instead of months, since BTG absorbs the regulatory and infrastructure complexity
  • Enterprise-grade security — mTLS webhook validation, API credential management, and certificate rotation come built into the integration
  • Simplified onboarding — BTG provides credentials directly when your institution signs up for indirect BACEN integration — no separate certification process required
