3.2 Technical Architecture

To enable efficient coordination between stablecoin networks and global fiat systems, UniPay has developed a layered technical architecture. This architecture is built on compliance and clearing as its foundation, with account and asset management at its core, and extends upward to payment networks and user interfaces — forming a complete operating system for payments and capital management.

Layer	Function	Core Value
Layer1	Compliance	Risk & legality
Layer2	Rules Engine	Value allocation
Layer3	Asset Layer	Capital efficiency
Layer4	Payment Layer	Global execution
Layer5	Interface	User access

Layer 1: Compliance & Risk Control Layer

The compliance and risk control layer serves as the foundation of the UniPay system, ensuring that all fund flows are compliant and controllable across multiple jurisdictions.

This layer integrates core mechanisms such as KYC (Know Your Customer), AML (Anti-Money Laundering), sanctions screening, and FATF Travel Rule compliance. It dynamically adapts to regulatory requirements in different regions.

From a technical perspective, this layer utilizes rule engines and real-time monitoring systems to assess transaction risk, classify user behavior, and provide compliance validation for settlement routing.

Layer 2: Rule & Incentive Engine

The rule and incentive engine acts as the system’s coordination and allocation core, defining how funds move within the network and how value is distributed.

Through algorithmic and rule-based models, this layer translates transaction activity, network contribution, and asset scale into quantifiable weights. These weights are then used to drive resource allocation, incentive distribution, and system-level optimization.

Layer 3: Asset Management Layer

The asset management layer serves as the central hub of the UniPay system, responsible for account structuring, fund segregation, and liquidity management.

Through a layered account design, different types of funds — including user funds, merchant funds, and platform funds — are managed in isolation while remaining interoperable within the system. This layer also provides unified balance management and capital routing capabilities, ensuring both security and efficiency in fund utilization.

Layer 4: Payment & Card Network Layer

The payment and card network layer connects global payment channels with real-world consumption scenarios, enabling UniPay’s payment capabilities.

This layer integrates the U Card system, cross-border payment rails, and real-time authorization and settlement mechanisms. It ensures that funds can be transferred and spent globally with speed and reliability.

By integrating with major card networks and local payment systems, UniPay supports both online and offline payment scenarios. Transaction authorization, risk validation, and settlement execution are handled within this layer, ensuring real-time processing and system security.

Layer 5: User & Enterprise Interface Layer

The interface layer serves as the unified entry point for external users, including individuals (C-end), enterprises (B-end), and institutional clients.

Through applications, web interfaces, and APIs, this layer provides a unified account interface and capital management experience. For individual users, it delivers intuitive asset management and payment functionality; for enterprises, it offers standardized APIs and backend systems for collections, payouts, and treasury management.

By abstracting complex infrastructure into user-friendly interfaces, UniPay reduces adoption barriers while enhancing scalability and integration across different use cases.
