Your institution owns its Pix participation; JD provides the certified connectivity layer that reaches BACEN's network. Because Lerian's Pix integration abstracts the connectivity provider behind a single API, the Pix documentation applies regardless of provider: * **[What is Pix?](/en/rails/pix/pix-overview)** — the rail itself: modalities, SPI, DICT, and participation models. * **[Pix Switch](/en/rails/pix/pix-switch)** — the orchestration layer that handles DICT management, transactions, QR Codes, and MED through one API. * **[Plugin use cases](/en/rails/pix/pix-use-cases)** — end-to-end scenarios combining Pix with fees, transaction routes, and the ledger. Provider-specific configuration for direct participation via JD is provisioned with your integration. Want to set up direct Pix participation?
