Hodl GRS Wallet - The easy and secure groestlcoin wallet for Android
This is the Android port of the Hodl GRS Wallet iOS app, which can be found here.
Unlike other Andriod Groestlcoin wallets, Hodl is a standalone Groestlcoin client. It connects directly to the Groestlcoin network using SPV mode, and doesn't rely on servers that can be hacked or disabled. Even if Hodl disappears, the app will continue to function, allowing users to access their money at any time. You can also recover Hodl's backup up recovery key in other Groestlcoin wallets if necessary as we follow BIP standards for wallet generation.
Hodl utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is Hodl's core design principle. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. Hodl is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
- Simplified payment verification for fast mobile performance
- No server to get hacked or go down
- Single backup phrase that works forever
- Private keys never leave your device
