Built for enterprise scale

Event-sourced, double-entry ledger with cryptographic verification, real-time processing, and governance-grade auditing built into the core.

Cryptographic Trust

Every transaction is cryptographically signed and hash-chained. Merkle anchors provide tamper-proof audit trails with deterministic replay capabilities.

  • SHA-256 event hashing with canonical JSON
  • Merkle tree anchors every N minutes
  • PQC-ready cryptographic interfaces

Real-time Processing

Zero-batch processing with accrue-on-mutation. Instant P&L calculations and real-time balance updates with 8-decimal precision.

  • Event-sourced architecture with CQRS
  • Lazy interest accrual with threshold controls
  • NUMERIC(38,8) precision for financial calculations

Fail-closed Safety

Comprehensive verifier pipeline with limits, velocity controls, and maker-checker approvals. Money never moves without proper verification.

  • Multi-layer verification pipeline
  • Real-time limits and velocity monitoring
  • Dual-control for high-risk operations

Multi-tenant by Design

Built-in tenant isolation with Row Level Security, Ory Keto authorization, and clean data partitioning for enterprise scale.

  • PostgreSQL RLS with session context
  • Ory Keto for fine-grained authorization
  • Automatic data partitioning and archival
