Custodial Integration Model

Xafer currently provides a Custodial Integration Model, where clients do not need to manage any private key material. Xafer securely handles the entire lifecycle of key generation, sharding, storage, and signing using a robust MPC-based infrastructure.

Clients integrate via simple API calls, enabling them to perform secure wallet operations without running signature nodes or managing cryptographic infrastructure. This model is ideal for Web3 products, SaaS platforms, and startups seeking fast, secure deployments with minimal engineering overhead.

Third-Party Wallet Integration

Xafer can be integrated as a backend security module into existing wallet services, exchanges, or transaction platforms. It’s designed to be UI-agnostic, allowing developers to maintain full control over frontend design and business workflows while outsourcing the cryptographic and risk control layer.

Use cases include:

  • Integrate Xafer's WaaS service into the backend to replace local private key management.

  • Receive deposit, withdrawal, and risk event notifications from Xafer.

This approach significantly enhances backend security and compliance readiness, with minimal changes to the existing architecture.

Integration Recommendations

Whether you're running an enterprise backend (ERP, finance), a SaaS product, or a Web3-native app, Xafer recommends modularizing your wallet layer as a standalone service. This decouples critical asset logic from your core application and improves risk isolation and maintainability.

Recommended practices:

  • Wrap Xafer APIs/SDK into internal service layers for consistent wallet access

  • Embed approval workflows within finance or compliance systems

  • Use webhooks to receive real-time alerts on risky operations or transaction events

This architecture scales well as business needs evolve, while maintaining a strong security posture.

Pre-Integration Checklist (Non-Technical)

Before proceeding with integration, enterprises should clarify the following:

  • Define wallet use case: Is it for user fund custody, treasury ops, or contract interaction? Different cases may require different flows.

  • Identify system touchpoints: Can your internal systems (e.g. finance, admin backend, risk tools) receive webhook alerts?

  • Team alignment: Are the technical, product, finance, and compliance teams aligned on roles, milestones, and deployment timelines?
