11 Purpose-Built Engines

Each engine is a self-contained domain handling a critical aspect of financial operations, from posting to compliance.

Posting Engine

100 TPS synchronous, 1,000+ asynchronous. Double-entry accounting with idempotent writes and atomic batch operations.

Mapping Engine

Bidirectional chart-of-accounts translation. COSIF to IFRS and back, with full audit trail of every mapping.

IFRS Measurement

Automated EIR, ECL, and Fair Value calculations. Full compliance with IFRS 9, IFRS 13, and IFRS 15 standards.

Validation Engine

4-stage validation pipeline with 50+ built-in rules. Schema, business logic, compliance, and balance checks before every posting.

Sandbox Engine

Isolated execution environment with full API parity. Automatic 30-day data purge with no impact on production.

Ledger Runtime

8 immutability guarantees enforced at the storage layer. Append-only writes, cryptographic hashing, and tamper-evident logs.

Reconciliation Engine

AI/ML-powered matching with 4-tier confidence scoring. Automatic, suggested, manual, and exception-based reconciliation.

Settlement Engine

5-state lifecycle management: initiated, authorized, clearing, settled, and finalized. Real-time position tracking.

Compliance Engine

1,600+ regulatory signals monitored in real time. Automated BACEN reporting, AML screening, and suspicious activity detection.

Billing Engine

Usage-based billing with IFRS 15 revenue recognition. Metered, tiered, and custom pricing models out of the box.

ATM Engine

ISO 20022 native messaging. PIX Saque and PIX Troco support with real-time authorization and settlement.

Domain-Driven Design + CQRS

Our ledger is architected with strict domain boundaries, command-query separation, and event-driven communication between bounded contexts.
