This article is a comprehensive 2025 guide to Multi-Party Computation (MPC) wallets, explaining their security advantages over traditional wallets, comparing leading providers like Zengo and Fireblocks, and helping both individual and institutional users choose the best secure crypto wallet for their needs.
TL;DR: As crypto threats grow more sophisticated, Multi-Party Computation (MPC) wallets offer advanced security by splitting private keys into encrypted shares, preventing single points of failure. This guide explains how MPC wallets work, compares leading providers like Zengo and Fireblocks, and helps individuals and institutions choose the best secure crypto wallet for 2025.
The cryptocurrency ecosystem is one of rapid, ruthless evolution.
In 2024, hackers stole $2.2 billion worth of digital assets, underscoring the relentless threat of wallet breaches, phishing schemes, and malware attacks. The security of traditional wallets is being outpaced by the growing scale and sophistication of cybercrime, and as hackers get more creative, so should our means to protect our funds.
Secure crypto wallets have become indispensable for asset protection in this day and age, and Multi-Party Computation wallets, colloquially known as MPC wallets, are among the most advanced options in the market today. They work by harnessing advanced cryptography to fragment private keys across several parties, providing an extra layer of security to keep your digital assets under multiple locks and keys.
The following guide will explore the mechanics, benefits, and application of MPC wallets, spotlighting key providers such as Zengo and Fireblocks, and providing detailed reviews on the different services available today for both private individuals and institutions.
What Are MPC Wallets?
Multi-Party Computation wallets represent the next step in crypto security. Unlike traditional wallets, which use a single key system associated with a seed phrase for access, MPC wallets use a special algorithm to create multiple encrypted parts of the key, called shares, which are then stored separately among different parties and devices. In order to access the funds, a number of holders of these shares must cooperate to authorise access (known as the Threshold Signature Scheme, TSS), thus ensuring that no single party can greenlight transactions on their own.
This can work in one of two ways. For individual users, the separate key shares may be distributed between the user’s main device, such as a computer or smartphone, the wallet provider’s server, which can request special information (such as facial recognition) to the user in order to authorise a transaction, and an optional third backup device, like a secondary phone. Two of these shares would be required to greenlight a transaction, so individual users would simply need to do a facial recognition scan or have both primary and secondary devices at hand to give the OK.
For institutions, meanwhile, the different shares can be split among the devices of multiple people, which inherently adds a higher degree of security to their digital assets by splitting authorisation among multiple decision makers. The system is also designed to prevent any single party from possessing the complete key, as a complex, secret algorithm is required to put the pieces together, drastically reducing the risk of theft or loss.
Compared to traditional, single-key wallets, MPC crypto security provides a considerable boost to asset safety. Traditional wallets may be more user-friendly (though this varies from wallet to wallet!), but a single mishap like a hacked email, stolen smartphone, or phishing attack can easily result in a user’s funds being irreversibly stolen. With an MPC wallet, meanwhile, only one of multiple key shares would fall into the wrong hands, while the rest would remain safe and sound.
Multisig vs MPC Wallets
Multisig wallets are a step above traditional wallets in terms of security. They use a multiple-key system to authorise access and sign transactions, and are generally considered to be more transparent as all key activity is recorded on-chain. However, there are key differences that make Multi-Party Computation wallets a safer option.
Firstly, MPC wallets have a single key that is cryptographically split into shares, rather than multiple keys spread between devices. This difference is critical, as hackers only need to acquire the keys in multisig wallets, while in MPC wallets, they need both the key shares and the cryptographic algorithm to put them together.
Secondly, as multisig wallets use multiple keys, each key leaves its own registry on the blockchain with every transaction, potentially exposing dangerous metadata. MPC wallets, meanwhile, carry out the entire authorization process off-chain, as instead of needing multiple keys, there is only a single key at work that needs to “come together” for transactions to go ahead.
Over the past few years, multiple institutions have made the jump from multisig to MPC wallets precisely because of these benefits. Corporate needs for that extra layer of privacy and security made MPC wallets ideal to protect both their digital assets and financial data, making them very attractive for banks, fintech companies, and Web3 developers.
MPC wallets offer great security systems with no single point of failure. Like the door of a bank vault, the multiple key share requirement ensures no single entity can abscond with the funds, and the off-chain authorisation system prevents any metadata from leaking into public records.
Why Use an MPC Wallet in 2025?
The cryptocurrency landscape in 2025 is vibrant with opportunities and fraught with challenges. If 2024 proved anything, it’s that high-profile hacks, phishing attacks, and crypto scams are still on the rise, and secure crypto wallets have become a must. Multi-Party Computation wallets handily address the security concern while retaining high compatibility and functionality, making them very attractive for both individual users and institutions alike.
Rising Cyber Threats
Artificial intelligence has been revolutionary for cybercriminals. From the use of highly advanced chatbots to trick users, to the integration of AI in the coding of sophisticated malware, hackers have been harnessing these new technologies in increasingly alarming ways. And given the online nature of the cryptocurrency market, crypto users are among the most targeted demographics. For an individual investor, the loss of their wallet key or falling victim to a scam can irreversibly wipe out years of hard work in an instant.
MPC wallets are the perfect solution to this problem. The multiple key share system can prevent an attacker from taking control of the user’s wallet by stealing a single key, and the off-chain authorisation protocols ensure no blockchain scraper can obtain any metadata from any of the key shares.
Retail vs Institutional Use
Whether you are a private investor or part of an institution, MPC wallets offer substantial security benefits over traditional wallet services.
For retail users, Multi-Party Computation wallets simultaneously improve and simplify security by combining the strengths of multi-factor authentication with the elimination of seed phrases. In most cases, funds in traditional wallets are stolen via malware, phishing, or social engineering, exploiting security systems, or tricking users into handing over their keys. With MPC wallets like Zengo, however, a security breach would only compromise a single key share, keeping your crypto intact, and the complete lack of seed phrases means users cannot be deceived into giving them away.
For institutional use, meanwhile, wallets such as Fireblocks provide robust infrastructure tailored to businesses, securing vast asset portfolios under MPC crypto security protocols. The splitting of key shares also allows for multiple decision makers to have simultaneous custody of the institution’s wallet, ensuring, first, that no single person can take control of the funds for themselves, and second, that should one member of the institution be hacked, the wallet will remain shut tight.
Key MPC Wallet Benefits
- Privacy: Unlike multisig wallets, which reveal transaction approvals on-chain, Multi-Party Computation wallets sign transactions off-chain, ensuring user anonymity.
- Security: By eliminating single points of failure, MPC wallets greatly reduce the risk of unauthorized access. Even if a device is lost or a server is hacked, funds remain secure without the threshold number of shares.
- Usability: Modern MPC wallets like Zengo and Fireblocks balance advanced cryptography with user-friendly designs, making them accessible to novices and experts alike.
As digital asset security becomes a larger and larger concern, MPC wallets position themselves as the leading choice for secure crypto wallets in 2025. Whether you are a retail user wishing to protect your personal investments or the manager of a corporate portfolio, MPC wallets offer the most secure and trustworthy service in the market today.
