# The extra layer of security Using proven and audited technology and best practices is the way to maximize security. The basic infrastructure on zkRace is built by integrating already existing solutions and practices that have been proven over time. The **encrypted seed phrase**, along with other sensitive data like **addresses**, **keys**, and **account data**, **is securely saved in the user’s local storage**. No online app, website or provider can access any of that secured data - the **user retains total control over their wallet**. To store and manage accounts, **MetaMask’s Eth-Keyring library is used**. We leverage audited and proven open source solutions to minimize the possibility of error. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
