Android Groestlwallet released

We’ve listened to the community and have created a fast, easy, sexy wallet.
Sticking to our core philosophy we neither hold nor have access to users’ Groestlcoins. Moreover, should groestlwallet ever get removed from Google Play it can be easily imported into the iOS version of groestlwallet or MultiGroestl HD.

Groestlwallet is designed to protect you from malware, browser security holes, even physical theft. With AES hardware encryption, app sandboxing, keychain and code signatures, groestlwallet represents a significant security advance over web and desktop wallets, and other mobile platforms.
Simplicity is groestlwallet’s core design principle. Because groestlwallet is “deterministic”, your balance and entire transaction history can be restored from just your recovery phrase.

Groestlwallet implementations:
BIP-0032 to implement a hierarchical deterministic wallet
BIP-0039 to implement a mnemonic code of mnemonic sentence for the generation of deterministic wallets (process for turning in into a BIP-0032 seed)
