State Bank of Pakistan Raast Payment Guide

1. What is Raast?

Raast is Pakistan’s instant payment infrastructure developed by the State Bank of Pakistan (SBP) under the National Financial Inclusion Strategy. Unlike legacy 1Link IBFT switches that rely on multi-stage batch clearing, Raast operates on real-time gross settlement (RTGS) principles, enabling transactions to clear within milliseconds.

2. Key Features of the Raast Network

• Instant Settlement: Transfers complete in under 500 milliseconds across commercial banks, microfinance banks, and EMIs.
• Zero Transaction Fees: Under SBP mandates, P2P transfers across Raast have zero transfer fees (PKR 0.00).
• Raast ID Alias: Users can link their registered Pakistani mobile phone number or CNIC as a human-friendly handle, removing the need to remember 24-character IBANs.
• ISO 20022 Financial Messaging: Fully compliant with global ISO 20022 messaging standards, ensuring seamless interoperability and fraud metadata detection.

3. How BATWA Integrates with Raast

BATWA introduces a next-generation client-to-switch architecture. While standard banking apps experience 2 to 4 second spinning loaders during transaction dispatch, BATWA uses pre-warmed TCP/TLS pipelines and lightweight binary protocol buffers, lowering end-to-end clearing latency to sub-50ms.

4. Security & Idempotency Protection

To prevent double-debiting caused by mobile network drops, every outbound Raast transfer in BATWA is stamped with an immutable cryptographic Idempotency-Key. Even if a user taps "Transfer" multiple times during an elevator ride or signal loss, the transaction executes exactly once.
