What are MPC Wallets? Secure your assets with the most notable MPC Wallets


What are MPC Wallets?

MPC stands for Multi-Party Computation, where multiple parties that hold separate private data, evaluate a computation without disclosing the confidential information. Applying this technology to digital wallets: with MPC Wallets, the private keys are broken down into multiple shares, encrypted, each held by a separate party. This means the private keys are not stored in one place, but across multiple parties in different locations.

Traditionally, private keys are mostly stored in either hot or cold wallets, for example:

  • Hot wallets: Metamask, Trust Wallet, exchanges, etc.
  • Cold wallets: Ledger, Trezor, etc.

However, with these storage methods, the keys are at risk of Single Point of Compromise (SPoC), and are vulnerable to attacks. In these cases, the hacker only needs to successfully attack one point of compromise, and the private keys will be gone, along with the assets stored inside those wallets.

How does an MPC Wallet work?

In simple terms, here’s how MPC works:

  • A number of participants will each hold a piece of private data;
  • The participants can use their private data to compute a public function, while keeping their own pieces of data private.

For example, considering you and two other friends want to know who has the highest salary, while keeping your specific salaries private. Each of you can give your salary details to a mutual trusted friend, then he or she can determine the highest one without revealing each person’s income.

The same applies to private keys in MPC Wallets:

  • Your Private Keys will be divided in multiple encrypted parts, decentralized and independently held by multiple parties, each blind to another;
  • When the key is needed, MPC is required to confirm that all parties (or a certain number of parties) approve the request before it is executed;
  • This ensures no individual can collect all pieces to form the complete private key, while also preventing hackers from making transactions, even when they have the control over the user’s device.
