Lerian is a complete, modular core banking platform. Each product covers one financial domain end to end. You adopt one product on its own, or you combine several into one platform. Lerian has six products: Midaz, Tracer, Matcher, Flowker, Lender, and Reporter. Midaz, including its separately deployed Tracer component, is source-available under the Elastic License 2.0 (ELv2). Matcher, Flowker, Lender, and Reporter are licensed to customers. ## Products *** Create ledgers, manage transactions, and use core entities like accounts and assets, with CRM and the Fees Engine built in as part of Midaz. Connect rails like Pix and TED. Validate transactions in real time, apply rules and spending limits, and return ALLOW, DENY, or REVIEW decisions. Validate external transactions against the ledger and surface mismatches. Built for accuracy, traceability, and automation. Orchestrate transaction flows using validations, approvals, and external triggers with logic and plugin coordination. Run the credit journey end to end: loan products, origination, servicing, accounting, and Brazil-first regulatory support. Generate and download reports from reusable templates, filter their data, and manage recurring reporting deadlines. Supports HTML, XML, CSV, PDF, and TXT output. ## Platform services *** Console, Access Manager, Streaming Hub, Multi-tenancy, and Observability are platform services. They serve every product and are not products themselves. Operate every Lerian product from one web interface, with one login and one navigation. Control human and machine access across the products, and issue the tokens each service trusts. Consume platform events and fan them out to your systems through signed webhooks, queues, or a pull API. Serve independent customer contexts from one deployment, and keep each request inside its own tenant. Collect metrics, traces, and logs from Lerian workloads through OpenTelemetry. ## Brazil Rails and Interfaces *** A Brazil rail is Lerian-owned messaging software that connects your institution to BACEN or to a market infrastructure, with no intermediary. An interface is the product surface over a rail. Lerian offers its own interfaces (TED Lerian, Pix Lerian) and partner interfaces (Pix JD, Pix BTG, TED JD, Payments BTG). Partner interfaces ship as Midaz plugins: separately deployed services that extend Midaz and that Lerian licenses separately. Read what each rail carries, and how Lerian native messaging reaches BACEN and the market infrastructures. Read the API, the ledger integration, and the operational controls for each payment product. ## Solutions *** Solutions group the catalog by the problem you solve: core banking, payment rails, reconciliation, loan management, and orchestration. Start from the problem you must solve, then see which products meet it.
