RVN Wallet for Android

The next step in wallet security

This wallet is designed to protect you from malware, browser security holes. With AES hardware encryption, app sandboxing, and verified boot, it represents a significant security advance over web and desktop wallets.

beautiful simplicity

Simplicity is the RVN wallet core design principle. A simple list of 12 words is all you need to restore your wallet on another device if yours is ever lost or broken. Because it is deterministic, your balance and transaction history can be recovered from just your backup words. These words are now compatible with the Ravencoin core wallet available here.
