MPC for Payment Processing Systems

Deploy a production-ready, compliant MPC wallet in weeks, not months. We provide the complete infrastructure—key management, transaction orchestration, and compliance tooling—so you can focus on your core product.

Replace vulnerable single-key storage with MPC's distributed key generation and signing. Private keys are never fully assembled, removing the single point of failure that attracts attackers and auditors' scrutiny.

Reduce engineering and security overhead by 70%+ by outsourcing complex cryptography and key lifecycle management. Our managed service includes 24/7 monitoring, automatic backups, and seamless key rotation.

Build with built-in compliance. Our architecture supports role-based access controls (RBAC), transaction policy engines, and detailed audit logs essential for FinCEN, Travel Rule, and future regulatory frameworks.

Process thousands of transactions per second with our horizontally scalable signing nodes. Achieve sub-second finality for user withdrawals and settlements, matching traditional payment rail performance.

Support any blockchain (EVM, Solana, Cosmos) and integrate with any L2 or rollup through our unified API. Add new networks in hours without re-architecting your core custody layer.

We conduct a deep-dive analysis of your existing payment stack and business logic to design a secure, scalable MPC architecture. This includes threat modeling, key management strategy, and defining clear integration points.

Our engineers deploy a production-ready MPC wallet infrastructure using audited libraries (e.g., GG20/GG18). We handle key generation, distributed signing ceremonies, and secure enclave setup for your specific chain support (EVM, Solana, etc.).

We build and integrate the core payment processing logic—batch settlements, multi-signature transaction flows, and fraud detection hooks—exposing a clean REST/WebSocket API for your front-end and back-end systems.

Every component undergoes rigorous unit, integration, and penetration testing. The final system is reviewed by our internal security team and prepared for external audit, with all findings remediated before launch.

We deploy the complete system to your staging environment and execute end-to-end payment simulations with real transaction volumes. This phase validates performance, reconciliations, and monitoring alerts.

We manage the production deployment, key ceremony, and initial transaction monitoring. Your team receives full documentation, and we provide 24/7 SRE support with defined SLAs for incident response and system health.
