The Oxen Wallet allows you to safely store and spend your Oxen how you wish. The Oxen Wallet is powered by remote nodes provided by the Oxen community and the Oxen team. Remote nodes allow you to synchronize with the blockchain without having to store all of the downloaded blocks on your device. The Oxen Wallet that you download on the Google Play Store is built from open source code hosted on Github here https://github.com/oxen-io/oxen-mobile-wallet. We welcome any feedback or contributions to our Github by creating issues or pull requests.
