Comparing MPC wallets with multisig wallets highlights their unique benefits. Both distribute control, but MPC splits the private key itself, strengthening security by removing single points of failure.

The shift from MultiSig to Threshold Signatures is crucial for secure cryptocurrency approvals. SBI Holdings and Binance‘s CEO prefer Threshold Signatures, predicting they’ll revolutionize custodian services. About twenty providers plan Threshold Signature wallets, supported by five reasons over MultiSig:

  1. Universal Integration vs. Customization: Threshold Signatures seamlessly integrate as standard on-chain signatures, unlike MultiSig’s varied signatures.
  2. Smaller, Cheaper Transactions: Threshold Signatures’ consistent single signature reduces transaction sizes, unlike MultiSig’s multiple signatures, inflating fees.
  3. Enhanced Privacy and Security: Threshold Signatures hide approver details, while MultiSig exposes signatures and security policies.
  4. Simple Key Share Refresh: Threshold Signatures refresh key shares with computation, unlike MultiSig’s complex on-chain process.
  5. Operational Flexibility: Off-chain Threshold Signatures adapt better to security models, regulations, and market demands.


While MultiSig has its place, maintaining it outweighs migrating to Threshold Signatures. Custodians and investors benefit from the security, privacy, flexibility, and efficiency of Threshold Signatures. As the digital asset landscape evolves, the move from MultiSig to Threshold Signatures becomes clearer.
