Solutions
Start from the problem you must solve. Each solution names the products that meet it.
Core banking
Run accounts, transactions, and regulatory reporting on a ledger you own, with the controls your regulator expects.
Payment rails
Reach Brazil’s payment systems through Lerian-owned messaging to BACEN, or through a connectivity partner.
Reconciliation
Match your own records against banks, PSPs, and ERPs without spreadsheets, and close the month with an audit trail.
Loan management system
Run the full credit journey, from product definition through origination and servicing, with payroll-loan connectivity for Brazil.
Orchestration engine
Coordinate the checks and approvals around a transaction, with a step-level record of what ran and what it returned.
Products

Where the platform meets Brazil’s payment system. A Brazil rail is Lerian’s own messaging with BACEN or a market infrastructure. An interface is the product surface over a rail, from Lerian or from a connectivity partner. Either way, you keep your ledger, your data, and your business logic.
Brazil Rails

Streaming Hub
Consume platform events and fan them out to your systems through signed webhooks, queues, or a pull API (the platform’s event delivery edge).
