MPCVault Institutional Custody Platform

MPCVault's flagship institutional custody platform is an enterprise-grade, non-custodial digital asset management solution designed for teams and businesses requiring multi-chain, multi-asset, and multi-signature capabilities. The platform provides comprehensive treasury management across Bitcoin, Ethereum, BNB Smart Chain, Solana, Base, Tron, Arbitrum, Optimism, TON, Sui, Aptos, Polygon, and all EVM-compatible networks.

Security Architecture

Built on patented multi-party computation (MPC) technology (US Patent 12362918B2), MPCVault splits private keys into three encrypted shares distributed across the user's device, Google Cloud (AMD SEV secure enclave), and Microsoft Azure (Intel SGX secure enclave). All three shares are required to sign transactions, with no single party ever holding the complete private key. The platform features periodic key rotation that automatically refreshes key shares to new values, invalidating any stolen shares. Patented MPC-based hardened derivation ensures that a compromise on one chain never risks assets on another chain.

Institutional Compliance

MPCVault is SOC 2 Type 2 certified and maintains NMLS License #2357870 (FinCEN ID 31000213664980), meeting institutional compliance requirements. The platform provides organization key share export functionality, allowing organizations to obtain a copy of their wallet's private keys to maintain absolute sovereign control and eliminate platform lock-in.

Governance and Controls

The platform enables purpose-built vaults with independent access controls, allowing organizations to segregate assets by function, team, or project. Each vault supports hierarchical management with role-based access controls, enabling organizations to add accountants with read-only access to transaction histories for seamless auditing without compromising security. Organizations can implement flexible approval workflows through Simple Mode (for quick setups) or Advanced Mode (for granular, volume-based manager approvals).

API and Integration

MPCVault provides comprehensive REST and gRPC APIs with a Client Signer SDK for programmatic signing, enabling organizations to build automated workflows and integrate digital asset operations into their existing systems. The API supports flexible account, key, and asset management through a unified interface, with official support for Go, Java, .NET, iOS, and additional languages. The platform offers no-complexity MPC setup that can be configured in minutes rather than days.

The API includes built-in security controls such as comprehensive audit logs, IP allowlist rules, transaction amount limits, and callback verification checks. All API communications maintain the same end-to-end encrypted architecture as the web and mobile platforms, ensuring zero-trust security across all access methods. The API provides access to 19+ built-in blockchain networks plus custom EVM network support, serving over 100 million API calls with consistent performance and reliability.

Multi-Asset and Multi-Chain Support

The platform supports all asset types across all blockchains without whitelisting requirements, including newly minted tokens. This universal support ensures organizations can manage emerging assets without delays or permission requirements. The wallet provides a unified address across all EVM chains, eliminating "wrong chain" transfer anxiety and simplifying multi-chain operations.
