Subaddresses are a built-in Monero protocol feature rather than a third-party add-on. They enable users to create distinct addresses for various purposes—such as separating freelance client payments, mining rewards, or business income—without the burden of managing multiple wallets or recovery phrases. Because these addresses are cryptographically linked to a single wallet, all funds remain accessible through one master recovery key.

Beyond simple organization, the privacy implications are significant. To an external observer, payments sent to different subaddresses appear unrelated, preventing the public linking of transactions that occurs when reusing a single address. Guarda’s implementation keeps this process non-custodial, ensuring that users maintain full control over their private keys across the wallet’s desktop, mobile, and web applications. By removing the technical friction typically associated with Monero’s advanced features, Guarda provides a practical solution for users who require more than just basic storage from their digital asset management tools.
