System Architecture Blueprint

Stage 01

High-Throughput Payment Rails Gateway

  • Direct webhook ingestion from UPI, IMPS, NEFT, and payment gateway switches
  • Mutual TLS 1.3 with hardware security module (HSM) signature checks
  • Streaming zero-loss ingest via distributed Redis Streams
Engineered Stack: FastAPI • Rust Ingest • Redis Streams • HSM
Stage 02

Cryptographic Reconciliation Engine

  • Double-entry bookkeeping state machine with automated balance assertions
  • SHA-256 transaction hash cross-verification across issuer and acquirer
  • Instant freeze on mismatched amount or timestamp anomalies
Engineered Stack: Rust State Engine • Python 3.12 • DuckDB • PostgreSQL
Stage 03

Core Banking Writeback & RBI Compliance

  • Two-phase commit writeback to Finacle, TCS BaNCS, and core ledgers
  • Statutory daily settlement summary generation for RBI regulatory compliance
  • Real-time treasury dashboard with instant variance alerting
Engineered Stack: Finacle API • ISO 20022 XML • OpenTelemetry • Prometheus
