MPC wallet,
key management & policy engine
Control over keys. Control over operations.
Zero third-party reliance.
Your keys never exist in one place
Private keys are the most sensitive component of digital assets. The Vault protects them through multiple independent layers, supported across all deployment models.
MPC Cryptography
The Vault uses true threshold MPC, a T-of-N signature scheme where each private key is split into shares distributed across client devices and TEE-secured servers. The key is never assembled in full at any single point, eliminating the risk of theft even in the event of a breach.
TEE Technology
Trusted Execution Environment (TEE) provides hardware-level isolation for key operations. Even if the surrounding server infrastructure is compromised, operations inside the TEE remain protected, and key shares cannot be extracted.
Your Sole Control
Private keys are generated and stored within the client’s own perimeter. The Vault infrastructure never has unilateral access to keys or the ability to sign transactions without client authorisation.
Multi-party computation wallet architecture is supported across all three deployment models, In-house, Cloud and Hybrid, with the same security guarantees at every level.
A policy engine that governs every fund movement
Structural governance enforced before any key share activates.
Step-by-step: how every transaction is governed
A multi-user wallet only delivers security if the approval process is strictly enforced.
Admins configure rules, limits, and quorums.
Authorised user creates a request. Initiators cannot approve.
Auto-check against predefined rules. Non-compliant requests are instantly rejected.
Routed to designated approvers based on policy quorum.
MPC key shares sign across devices and TEE servers.
Submitted to the blockchain.
Complete visibility across every wallet and operation
Audit-ready architecture with deep operational visibility built for regulated environments.
Comprehensive audit trail
Every operation captures initiator, approvers, timestamps, and device identifiers.
End-to-end monitoring
Full visibility across all wallets for compliance and finance teams.
Cryptographic integrity
Tamper-resistant databases ensure audit logs cannot be altered retroactively.
Complete attribution
Nothing is anonymous. Every decision is tracked to a specific user & device.
Same security architecture, deployed your way.
Choose where The Vault runs. The MPC key management and policy engine operate identically in every configuration.
