💡 Overview

Exchange Platform v3 is a multi-tenant exchange infrastructure that lets organizations run their own branded currency-exchange and P2P trading desk. Each tenant gets isolated data, custom branding, configurable fees, and a full role hierarchy out of the box.

Designed for currency exchange offices, crypto OTC desks, and B2B remittance operators that need white-label infrastructure without building from scratch.
