What is Simo Rail?
Simo Rail is a self-service, 24/7 virtual Buddy Bank testing solution for RT1 payment rail certification and regression testing
It lets banks spin up a virtual test counterparty in the cloud to send/receive RT1 payments, validate ISO 20022 messages, run scheduled and volume tests, and track test history—all without coordinating with real partner banks. Simo Rail includes off-the-shelf scenarios, full message validation and supports different tiers (Pro/Integrated) for deeper integration and higher test capacity.
