Multi-signature wallet

Advantages:

Clear logic and widely applicable to the current blockchain ecosystem.

Completely operated on the chain, with high transparency.

Disadvantages:

Depends on on-chain functions and has high execution costs.

Private keys need to be managed separately and are vulnerable to single point attacks.

MPC Wallet

Advantages:

High privacy and security, the private key never leaves the sharded storage.

It saves on-chain operation costs and is more suitable for large-scale applications.

Disadvantages:

High implementation complexity and reliance on advanced cryptography algorithms.

Specialized infrastructure is required to support multi-party computation.

Summary

Multi-signature wallet: more suitable for scenarios that require high transparency and complete on-chain operations, such as DAO or on-chain governance.

MPC Wallet: More suitable for applications that pursue privacy and security and optimize off-chain costs, such as enterprise-level asset management or high-security personal wallets.

Choosing the right solution based on your needs is the key!
