Production-Grade UPI Liquidity Gateway

GoaPay Payment Gateway & Liquidity Clearing Network

Next-generation UPI routing connecting Merchants, QR Providers, Sub-Operators, and Brokers/Agents with strict Dual-UTR reconciliation and atomic wallet exposure reservation.

Core System Architecture

How GoaPay Reconciles & Settles Payments

End-to-end atomic workflow ensuring zero exposure leaks and instant dual-key verification

Stage 01

Atomic Exposure Reservation

When a merchant initiates an order, the system assigns an eligible QR Provider where order_amount ≤ available_balance, instantly locking exposure atomically in SQLite ledger.

Stage 02

5-Minute TTL Dynamic Checkout

Customers pay via dynamically assigned UPI QR. If unpaid within 5 minutes, the session auto-expires and locked exposure safely returns to the provider with zero manual intervention.

Stage 03

Dual-UTR Atomic Settlement

Dual verification: UTR is matched against QR Provider / Admin verification. On match, multi-party wallets (Merchant, Provider, Broker, Agent) credit & debit instantly.
