Key Share Distribution
MPCVault uses a 3-of-3 multi-party computation (MPC) setup:
All three shares are required for signing. No single party ever has access to the complete private key.
Multi-Cloud Infrastructure
MPCVault operates across multiple cloud providers, each using a different Trusted Execution Environment (TEE):
This orthogonal platform design reduces the risk of compromise - a vulnerability in one TEE technology doesn’t affect the other.
No Counterparty Risk
Unlike centralized custody providers, MPCVault never holds all your key shares. This eliminates counterparty risk - you always know where your assets are and maintain control over them. You can:- Request your key shares from MPCVault at any time
- Designate a Trust to hold encrypted backups for recovery independent of MPCVault
