MPCVault is an innovative non-custodial Web3 wallet platform designed for teams and businesses to effectively manage their on-chain assets across various blockchain networks, featuring multi-signature governance and robust cryptographic safeguards. This system allows for collaborative control over treasury management, offering hierarchical permissions and adaptable transaction policies while ensuring that private keys remain undisclosed.

Users have the capability to establish multiple vaults tailored for distinct business needs, including operational accounts, reserve assets, or vesting funds, with each vault hosting its own member roles and policy configurations. Furthermore, it provides a seamless management experience for assets, tokens, and NFTs within a singular interface, showcasing real-time transaction histories and offering exportable records that resemble bank statements, assisting in reconciliation and compliance efforts. This comprehensive approach not only enhances security but also streamlines financial oversight for organizations, ensuring that their digital assets are managed efficiently and transparently.
