Trust infrastructure · open source
Financial primitives you can inspect, audit, and trust
Flomisma publishes its transport, ledger, and task queue layers as open source. No pricing. No sales. The repo is the product.
Bank infrastructure
Invoice audit infrastructure for banks
Flomisma provides the audit and verification rail for bank invoice workflows. Banks issue invoices and receive payments through their own systems. Flomisma records every state transition, verifies conditions against bank-reported data, reconciles multi-party ledgers at ISO 20022 maximum precision (18 decimal places), and produces a cryptographically attestable audit trail. Flomisma does not move or hold funds.

BSL 1.1 — inspect and audit, commercial license required
These modules are readable and auditable. Production deployment in a competing product requires a commercial agreement. BSL converts to Apache 2.0 after four years.
GitHub packages ship bare algorithm primitives (no database or UI); paid templates wire the same concepts into production-ready Next.js + Prisma applications. View integrated templates →
Settlement reconciliation algorithm — multi-party ledger diff and conflict resolution.
Agent risk classification — scoring model and threshold gating for autonomous agent operations.
Condition evaluation, release trigger logic, and dispute routing for escrow lifecycle management.
