The Digital Asset Wallet Revolution: A Multidimensional Comparison of Popular MPC Wallets

Validated Project

The landscape of digital asset wallets is undergoing significant transformation. With the advent of Web3, there have been increasing infrastructure requirements and notable challenges. Digital wallets, being primary access points to digital assets, are often the targets of malicious attacks and face problems such as lost private keys. This has led to a demand for more secure and user-friendly decentralized wallet solutions. In response, numerous crypto companies are striving to develop wallet products that resonate with contemporary needs, signaling the evolution toward the Wallet 2.0 era.

Two innovations in this space, MPC wallets and smart contract wallets have been recognized as next-generation solutions, particularly in addressing the challenge of private key management.

MPC wallets, with their compatibility, privacy, and cost-effectiveness, are increasingly being viewed as promising off-chain solutions for near-term implementation. This is evident from the emergence of consumer-facing products like UniPass and ZenGo. Additionally, seasoned industry entities such as ChainUp Custody are integrating MPC technology into their digital asset custody services.

The question arises: Why is there a growing interest in MPC wallets? How do they stand out when compared to conventional wallets? Several entities are participating in this domain, each offering unique features. This exploration aims to provide insights into the essence of MPC wallets, trace the journey from Wallet 1.0 to 2.0, and highlight the potential benefits of the emerging wallet generation for the industry.

1. The Decentralized Private Key Approach of MPC Wallets

1.1 What is an MPC Wallet?

MPC, or "Multi-Party Computation," is a cryptographic technique that originated in 1982. It involves multiple participants collaboratively achieving a computational goal without any trustworthy third party. Each participant only knows their computational results and cannot access any information from other participants.

The integration of MPC technology with digital asset wallets achieves the goal of "decentralizing mnemonic phrases/private keys."

In the design of an MPC wallet, the private key is split into multiple segments and shared among various decentralized entities or platforms. Importantly, each of these participants holds only a piece of the private key, remaining unaware of the segments others retain. When a transaction demands a private key signature, these individual segments are collaboratively assembled to execute the sign-off. This decentralized approach to private key management effectively addresses concerns over its safekeeping. Thus, even if a fragment of a user's private key were compromised, intruders would remain unable to access the wallet's contents.
