How are Private Keys Stored in Crypto Wallets

Updated: Jul 19



Private keys are a crucial component of cryptocurrency ownership, and their security is of utmost importance. That’s why the MPC, Multi-Party Computation, is game-changing in 2023. This technology involves breaking up the private key into several shares, which are then distributed among different trusted parties. This ensures that no single party has access to the complete private key, making it more secure. Additionally, the shares are encrypted using a secure algorithm, so it’s impossible for hackers to access them as they have to attack multiple parties at the same time in order to breach the security wall.


Fascinating right? Fortunately, Nativ wallet, using CYBAVO’s MPC, also implements this unique approach to store private keys.

“CYBAVO”, A Service provider of MPC Technology

CYBAVO is a reliable provider of MPC and blockchain solutions, offering an all-in-one solution for blockchain management with on-premise key storage and MPC technology to ensure full protection of private keys. As a subsidiary of Circle, CYBAVO's innovative solutions provide a seamless experience for clients without compromising security and speed.


Nativ wallet utilizes CYBAVO's world-class security, combined with a user-friendly interface, to provide the best of both worlds—an easy and secure wallet for users of every generation you might not find somewhere else in South East Asia.



Non-MPCand Hardware Wallet: The drawbacks

Some might ask “Why is it so important to have MPC these days while we have other options that are more secure?” Well, there is the fact that storing cryptocurrency on non-MPC custodial platforms and hardware wallets can be risky due to potential vulnerabilities such as phishing, malware, supply chain attacks, and hardware vulnerabilities. Furthermore, although cold wallets offer increased security, they sacrifice convenience and can still be breached if users make mistakes. On the other hand, MPC-based solutions offer a new approach to securing digital assets, distributing trust among multiple parties and making it more difficult for attackers to compromise security.


As previously mentioned, Nativ's crypto wallet sees this pain point of choosing between security and accessibility. Therefore, it comes with a better alternative that offers a balance in a pendulum, combining top-tier MPC private key keeping technology and a well-designed UX/UI for a smooth user experience in the app.



Multi-Party Computation (MPC) in short

In essence, Multi-Party Computation (MPC) is a technology that allows multiple parties to work together without revealing data to others in the group. MPC works by merging private keys with the secret sharing principle called Threshold Signature Scheme (TSS), which enables secure data sharing and transactions without the need to provide real keys to a custodian (Nativ). With MPC, private keys are split and shared among different parties, eliminating a single point of failure. In fact, this technology can be used in various industries, especially cryptocurrency, to ensure the highest level of security for private keys.


Nativ is an MPC-based service provider that offers a secure key vault for private keys with support for over 4 main cryptocurrencies (BTC, ETH, USDC, USDT, ) and more to come!




How your Private key is actually stored

At Nativ, the private key of your crypto wallet will be encrypted, split, then kept between 3 main parties, in this case—you, Nativ wallet, and CYBAVO cloud, with each adding their section of the key without revealing or accessing the other parts of the key. This ensures that the private key is still safe and even more secure than ever despite the fact that your money is only protected by a 6-digit PIN—not the whole 24-seed phrase as in other traditional crypto wallets. Rest assured that no single party can access or manipulate it when your assets are in Nativ wallet





Interesting Wallet in The Market Several other wallets also use MPC to store private keys, and each of these wallets has its pros and cons.

One of the major advantages of Casa Wallet is its robust security, which makes it an ideal option for individuals and businesses seeking to safeguard their digital assets.

It supports multiple cryptocurrencies and allows users to purchase crypto directly from the app. One of the main advantages of ZenGo is its easy-to-use interface, which makes it an excellent option for beginners. Additionally, the wallet does not store users' private keys, which adds an extra layer of security. However, ZenGo may not offer the same level of advanced security features as other wallets, and some users may find its fees to be relatively high.


4.Fireblocks Wallet

Overall, all five wallets offer high levels of security through the use of MPC technology. However, they differ in terms of user-friendliness, supported cryptocurrencies, and pricing; yet none of them offers something in between except Nativ wallet that focuses on a user-friendly interface with sufficient necessary functions to save, spend, and earn cryptocurrency for everyone.
