Core Banking & Inter-Ledger Parity

Verify multi-currency ledger balances, reconcile nostro/vostro correspondent accounts, and satisfy stringent regulatory audit mandates with deterministic exactness.

Complex Banking Ledger Topology

Banking architectures frequently combine core legacy COBOL/AS400 mainframe databases with modern event-driven payment microservices and external clearing houses (SWIFT, Fedwire, RTGS).

USE CASE 01

Nostro / Vostro Shadow Accounting

Compare internal mirror accounts against daily statement messages (MT940/MT950) from foreign correspondent banks. Catch value-date discrepancies and foreign exchange rounding variances instantly.

USE CASE 02

General Ledger to Sub-Ledger Balancing

Perform end-of-day deterministic reconciliations between deposit sub-ledgers, loan accounting engines, and the central general ledger across millions of individual accounts.

USE CASE 03

Regulatory Audit Trails & Traceability

Produce mathematically verified, immutable execution fingerprints for internal audit, statutory auditors, and central bank compliance bodies without disclosing sensitive cardholder or account data.

FINANCIAL PRECISION

Exact Fixed-Point Decimal Arithmetic

Standard double-precision IEEE-754 floating point numbers cannot accurately represent currency fractions (e.g. 0.1 + 0.2 ≠ 0.3). Rift’s canonical type system handles exact fixed-point decimals, preventing false positives and ensuring every paisa or cent balances to zero.

Exact scale & precision preserving decimal type
Composite keys (e.g. branch_code, account_no, currency)
Explicit policy-controlled duplicate key resolution
