MPCVault Wallet Platform

MPCVault's flagship non-custodial wallet platform is an institution-grade 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.

Core Features

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. The wallet provides a unified address across all EVM chains, eliminating "wrong chain" transfer anxiety and simplifying multi-chain operations.

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.

Governance and Policies

Organizations can implement flexible approval workflows through Simple Mode (for quick setups) or Advanced Mode (for granular, volume-based manager approvals). The platform supports multi-signature requirements for smart contract owner accounts, with clearly decoded transaction details before approval. Transaction simulation shows exactly what will happen to balances before signing, while parameter decoding translates complex smart contract interactions into human-readable text.

Compliance and Certification

MPCVault is SOC 2 Type 2 certified and maintains NMLS License #2357870 (FinCEN ID 31000213664980). 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.

Multi-Asset 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.
