Sensitive Transactions Managing
Seamless integration with US-based Passport payments, including KYC, sub-account creation, escrow-like logic, and conditional funds access
Priority integration:
We used Priority Passport as the foundation of our financial infrastructure to automate mass payouts for class-action and collective lawsuits. Based on the Priority Passport functionality, we implemented KYC integration, sub-account creation, fund distribution logic, calculation of withholdings, fees, and payouts under various scenarios, as well as fund access management based on user status.
Result: The platform supports payouts for X,000+ participants within a single settlement workflow, with 100% of standard calculation rules for withholdings, fees, and fund distribution executed automatically, while KYC and sub-account creation are initiated directly from within the platform.
