GRS

GRS is a fast, easy, sexy wallet. Sticking to our core philosophy we neither hold nor have access to users' Groestlcoins.

GRS is a real standalone Groestlcoin client. There is no server to get hacked or go down, so you can always access your money. Using SPV mode, GRS connects directly to the Groestlcoin network with the fast performance you need on a mobile device.
GRS is designed to protect you from malware, browser security holes, even physical theft. With AES hardware encryption, app sandboxing, and verified boot, GRS represents a significant security advance over web and desktop wallets.
Simplicity is GRS's core design principle. A simple backup phrase is all you need to restore your wallet on another device if yours is ever lost or broken. Because GRS is deterministic, your balance and transaction history can be recovered from just your backup phrase.
