Problem
Managing on-chain assets across multiple blockchains can be complex and insecure for teams, often requiring the sharing of private keys and making it difficult to enforce compliance policies. Existing multi-signature solutions may not support all asset types or provide the same address across different EVM chains, leading to operational inefficiencies and increased risk.
Solution
MPCVault is a non-custodial, multi-chain wallet that uses multi-party computation (MPC) and multi-signature technology to provide a secure and efficient way for teams to manage on-chain assets. The platform eliminates the need to directly handle private keys by generating key shares independently in multiple locations, including the user's phone. MPCVault supports the same address across all EVM chains and manages all asset types without whitelisting requirements. Its policy engine allows for flexible multi-sig policies and access control based on transaction volume and destination addresses.
Target Audience
MPCVault targets Web3 companies, DeFi protocols, and other organizations that need a secure and efficient way to manage their on-chain assets across multiple blockchains.
