Multi-Party Computation (MPC) is a key feature of Gridlock's mobile wallet that enhances security by preventing theft from any individual node in the network. MPC works by dividing the user's private keys into shares that are distributed across multiple parties. Each party holds only a portion of the private key and has no complete access to the user's assets. This means that even if one party's node is compromised, an attacker cannot gain full access to the user's private key or steal their crypto. To complete a transaction, a certain threshold of parties must collaborate and contribute their key shares. This threshold ensures that no single party can perform a transaction alone without the involvement of others. By distributing the private keys in this way, Gridlock's wallet eliminates the risk of a single point of failure, making it extremely difficult for any individual node to steal the user's crypto assets. This advanced MPC technology provides a high level of security and gives users peace of mind when managing their digital assets with Gridlock. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.gridlock.network/guardians/all-about-guardians/why-cant-a-guardian-steal-my-crypto.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
