Definition

MPC (Multi-Party Computation) wallet is a cryptocurrency wallet technology that uses cryptographic protocols to enable secure wallet management without traditional private keys. Instead of a single private key, the key is distributed across multiple parties using mathematical algorithms.

Key Points

  • Security: No single point of failure - private key is split across parties
  • Accessibility: Enables secure on-chain activities without key management complexity
  • Mobile-friendly: Suitable for mobile cryptocurrency applications
  • Custody: Self-custodial model maintains user control

How MPC Works

  1. Private key is split into multiple shares using mathematical Secret Sharing schemes
  2. Transactions require signatures from multiple parties
  3. No single party ever sees the complete private key
  4. Users can recover wallet via recovery phrases (sharding)
