What is an MPC Wallet?
MPC (Multi-Party Computation) wallets use cryptographic techniques to split private key control across multiple parties. No single party ever holds the complete key, yet transactions can still be authorized.
How MPC Works
Private key is mathematically split into shares
Each party holds one share
Threshold of parties required to sign (e.g., 2-of-3)
Key shares never combined; signing happens distributedly
Advantages Over Multi-Sig
No on-chain footprint: Looks like regular transaction
Flexible policies: Easy to change signers
Cross-chain: Works across all blockchains
Key refresh: Can rotate key shares without changing address
