We believe financial infrastructure should be inspectable, extensible, and owned by those who operate it. Source-available is not a positioning strategy for us. It is an architectural principle. Midaz is open because financial systems require transparency, control, and long-term sustainability.

Why Source-available?


Source-available creates structural advantages — not just community engagement. By making our products open, we enable: Transparency Every line of code is visible and auditable. No hidden logic. No opaque behavior. Independence Institutions control their stack. No forced upgrades. No vendor lock-in. Extensibility Teams can adapt the ledger to their regulatory, operational, and product requirements. Trust by design Visibility reduces systemic risk. You understand how your infrastructure behaves — because you can inspect it.

What source-available means for your business


For decision makers evaluating Lerian, source-available translates into concrete business benefits:
  • No vendor dependency: If Lerian disappears tomorrow, you still have the code. Your operations continue
  • Third-party auditability: Your security team, auditors, or regulators can inspect the code directly — no NDAs or trust-me-it-works conversations
  • Predictable costs: No surprise license escalations. You know what you run and what you pay for
  • Talent flexibility: Your engineers can debug, extend, and maintain the platform without waiting for vendor support tickets
