MPC Node Suite

Safeheron MPC Node Suite is a fully privatized, white-label MPC key management solution that enables businesses to build their own MPC wallet applications with complete data ownership and privacy.

Product Overview

The MPC Node Suite delivers enterprise-grade Wallet-as-a-Service infrastructure, allowing crypto exchanges, payment service providers, and self-custody platforms to embed institutional-level MPC wallet capabilities directly into their own products. Built on open-source MPC-TSS algorithms in C++ that have undergone rigorous third-party security audits, the suite is battle-tested with over $150 billion in asset transfers and zero asset losses.

• Client-Side SDKs: Embedded MPC Node SDKs for browsers, Android, and iOS enabling seamless cross-platform wallet applications
• Intel SGX TEE Integration: Secure enclave protection throughout the entire lifecycle of cloud-based key shard management
• Open-Source Algorithms: World's first open-source mainstream MPC-TSS library implementing GG18, GG20, and Lindell 17 protocols

Supported Business Scenarios

• Keyless Wallets: Build 2/2 or 2/3 MPC-TSS threshold wallets with open-source algorithms and key shard recovery protocols
• Financial Platforms: Institutional-grade infrastructure for payment and financial service applications
• Self-Custody Service Providers: Infrastructure for companies building self-custody products for their end customers
• Cold Wallet Solutions: Fully offline signing infrastructure for maximum security requirements
