Security is a major concern when it comes to cryptocurrency wallets, with the loss or misplacement of a private key potentially leading to huge losses. This presents a significant hurdle for the widespread acceptance and continued adoption of Web3 technologies. To address these challenges, Web3 developers are turning to innovative solutions like multi-party computation (MPC) and multi-signature wallets. But what is an MPC wallet? And what is a multisig wallet? If you’re looking for the answers to these questions, join us in the article as we explore the intricacies of both these wallet types!


In today’s article, we’ll dive into the ins and outs of MPC and multisig wallets. In doing so, we’ll explain what they are, how they work, and highlight the advantages they offer in the digital asset space.

Nonetheless, let’s get right into it by answering the question, ”What is an MPC wallet?”

What is an MPC Wallet? 

Multi-party computation (MPC) wallets are smart contract wallets leveraging advanced cryptographic protocols to enable multiple parties to collectively control and manage digital assets on a blockchain network. This is accomplished by splitting a wallet’s private key into numerous shares, which are distributed to various stakeholders that together generate transaction signatures!  

So, how do MPC wallets work? 

To understand how MPC wallets work, we initially need to briefly break down the basics of multi-party computations. In short, MPC technology allows multiple parties to jointly evaluate and compute a function using private data without ever having to reveal their individual inputs. To clarify this, let’s look at a simple example. 

Imagine the following scenario: Rob, Bob, and Sam want to find out who has the highest salary, but they don’t want to disclose to one another what they individually make. This is possible with an MPC protocol, where they can calculate the highest salary using their inputs without revealing any private information.

In the context of MPC wallets, the private key is split into several shares that are divided amongst various stakeholders. These stakeholders then collectively contribute to generating transaction signatures using MPC technology, meaning they never have to reveal their part of the key to the other participants. Consequently, there isn’t a time when the private key is fully reconstructed in one place.

In summary, an MPC wallet splits the private key into numerous shares and divides them among multiple stakeholders. Together, the participants can generate a transaction signature without ever reconstructing the complete private key in one place. This significantly boosts security and improves flexibility! 

Benefits of Using an MPC Wallet 

Using an MPC wallet provides loads of benefits, and in this section, we’ll look at three prominent examples: 

  • Enhanced Security: As MPC wallets divide private keys into multiple shares – which are distributed among various participants – it significantly improves security as this approach removes the single point of failure conventional Web3 wallets have. 
  • Improved Flexibility: MPC wallets enable more flexibility when it comes to access control and permission settings. This allows users to define roles and responsibilities for each participant, a particularly useful feature for organizations that need strict control over their digital assets. 
  • Cost-Efficiency: MPC wallets typically require fewer on-chain transactions compared to – for instance, multisig wallets, making them cheaper to set up, maintain, and manage. 

What is a Multisig Wallet? 

Multisig wallets – short for ”multi-signature wallets” – are cryptocurrency wallets requiring several signatures – from different people or devices – to manage funds and execute transactions. This approach significantly enhances security and is often used for managing shared funds! 

So, how do multisig wallets work? 

In short, a multisig wallet leverages smart contracts to distribute multiple private keys and define rules for usage, such as the minimum number of signatures required to execute transactions. Any participant in a multisig wallet can typically initiate transactions. However, it will remain pending until the necessary number of private keys has been used to sign the transaction. 

Requiring multiple signatures mitigates the risks of malicious actors taking control of the funds, as they can’t do much even if they get their hands on a private key. What’s more, since control can be distributed among multiple participants, it opens up the opportunity for users to manage shared funds more efficiently. 

All in all, a multisig wallet distributes two or more private keys and requires multiple signatures to manage funds and execute transactions. This significantly improves security and opens up the opportunity for users to manage funds collectively in a safe manner! 

Benefits of Using a Multisig Wallet 

Like MCP wallets, multisig wallets also provide many benefits, and down below, you’ll find three examples: 

  • Improved Security: Since multisig wallets require more than one private key to execute transactions, it minimizes the risks of losing funds if one of the keys gets into the wrong hands. In essence, multisig wallets remove the single point of failure most conventional wallets have. 
  • Cooperation Between Parties: Multisig wallets facilitate shared control over funds and assets, which is perfect for organizations, partnerships, and other groups where the decisions about asset movement should be a collective process. 
  • Reduced Risk of Fraud: Multisig wallets need more than one signature to execute transactions, minimizing the risk of one participant acting maliciously by trying to steal funds from the wallet. 

MPC Wallet vs Multisig Wallet 

Now, with an overview of both MPC and multisig wallets, let’s compare them to highlight their similarities and differences!

Both MPC and multisig wallets serve to enhance the security, flexibility, and control over digital assets by involving multiple parties in transaction approvals. Yet, they are not the same, as they operate using different underlying mechanisms.

MPC wallets leverage a cryptographic technique where one private key is divided into multiple shares that are distributed among participants. From there, the parties jointly perform computations required to, for instance, sign transactions. In doing so, the private key is never reconstructed in its entirety. 

Multisig wallets, on the other hand, require several signatures from multiple parties to authorize transactions. As such, rather than dividing the private key into shares, these wallets distribute multiple separate keys to involved participants. 

So, while MPC and multisig wallets serve the same purpose and both involve multiple parties in the transaction process, they differ significantly in how they handle private keys. In essence, MPC wallets rely on splitting the private key, while multisig wallets distribute individual keys to each participant.

Summary: What are an MPC Wallet and a Multisig Wallet 

In today’s article, we kicked things off by diving into the intricacies of MPC wallets. In doing so, we learned that an MPC wallet is a smart contract wallet splitting its private key into shares that are distributed to multiple stakeholders. The stakeholders can then collectively generate transaction signatures without ever having to reconstruct the full key in one place.

From there, we additionally explored multisig wallets, where we learned that they are cryptocurrency wallets requiring multiple signatures from different people or devices to execute transactions and manage funds. This is possible by distributing numerous private keys and defining clear usage rules through smart contracts.

Next, we compared MPC and multisig wallets to one another, where we learned that they both serve the same purpose. However, they operate using different underlying mechanisms. MPC wallets split the private key into fragments, while multisig wallets use multiple private keys to sign transactions.
