Overview
An MPC wallet uses multi-party computation to split signing keys across devices without ever combining them. It distributes security across multiple parties. It is an alternative to hardware wallets.
How It Works
The private key is split into shares held by different devices or parties. Transactions require a threshold of shares to sign, computed without reconstructing the full key. This reduces single points of failure.
Why It Matters
MPC wallets offer strong security with better usability than hardware wallets, and are used by institutions and dapps. They eliminate single-key compromise. They are a growing category in custody.
