Banner MPCVault is a non-custodial wallet for teams built on multi-party computation (MPC) technology. Unlike traditional wallets where a single private key controls your assets, MPCVault splits your key into three shares distributed across your device and two separate cloud environments. All three shares are required to sign transactions—no single party ever has complete control. Over 1,000 active organizations trust MPCVault to secure their assets, processing more than $2 billion in daily transaction volume. Our customers include leading exchanges, crypto VCs, Web3 firms, hedge funds, and trading desks worldwide.

​
How It Works

When you sign a transaction, all three parties compute their part without ever reconstructing the full private key. This eliminates single points of failure and removes counterparty risk.
