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