Groestlcoin is excited to announce our new HTML5 instant wallet, JSWallet. We've listened to the community and have created a fast, easy, sexy wallet for iOS.
                                   
Sticking to our core philosophy we neither hold nor have access to users' Groestlcoins as all keys and info are stored client-side. Moreover, should our site ever go offline your wallet can be easily imported into another wallet system.
                                   
Create a wallet in under 5 seconds by moving your finger on the device without having to provide any user information. The client-side input of the motions generate entropy (randomness) which is couple with a random generator to create a Groestlcoin wallet.

You can consider JSWallet a hot wallet where your secret URL is your key, a key that can be further secured with a password should you so choose. JSWallet generates a brand new wallet with a public key. Look in the URL/address bar and you will see a random-looking string starting with '#' or hash – the code after the hash is your brain wallet seed, and is a 'secret link' not visible anywhere other than on your local browser. Either copy the full URL somewhere safe or bookmark it for future access.

Features
• No logins required
• Optional passwords
• Works on multiple devices
• Create a brainwallet
• Groestlcoins stored on client-side
• Written in HTML5
• Takes only 5 seconds
• Set your preferred fiat currency
• Export private key
• Export brainwallet key
• Set custom fee
• Easter egg 1 (fake send): Enter "vapor" in the amount box
• Easter egg 2 (huge balance): Enter "ballin" in the amount box
• Easter egg 3 (huge balance with sound): Enter "baron" in the amount box
• Easter egg 4 (play turn down for what): Enter "tdfw" in the amount box
• Easter egg 5 (stop playing sound): Enter "stop" in the amount box

Create your own URL by using a brainwallet. A brainwallet refers to a random passphrase that only you know. This allows you to easily remember your URL and type it on any browser to retrieve your wallet. Choosing a secure passphrase is critical. Typically a good passphrase is:
• At least 10 words long
• Use letters, capitals, numbers, and spaces
• Never been written in a book, song, or password system
• Easy for you to remember
• Impossible for someone to guess

It is appreciated if feedback of the following is provided:
1.  Can you receive coins? (small amounts to avoid losing them)
2.  Can you send coins?
3.  Can you scan a QR code from another phone?
4.  Do you hear a sound when sending and receiving?
5.  Does it work on all (mobile) iphone versions?
6.  Does the transaction takes couple of seconds?
7.  Does it calculate exchange rates properly?

Important:
Export your private key

Now Groestlcoin testnet addresses and their corresponding private key can be conveniently generated in a web browser.
If you leave/refresh the site or press the "Generate New Address" button then a new private key will be generated and the previously displayed private key will not be retrievable. Your Groestlcoin private key should be kept a secret. Treat a paper Testnet wallet not like cash.
Check your balance by going to https://chainz.cryptoid.info/grs-test and entering your Groestlcoin Testnet address.

Features
• Offline single Address creation.
• Offline bulk Address creation.
• Offline brain Address creation.
• Offline vanity Address creation.
• QR code support
• In browser Key (re)generation.
• Ability to view wallet details by entering the private key.

Live version available at http://www.groestlcoin.org/testpaper.html. But it is recommended to download the testnet paperwallet offline and run it on your pc. Open testpaper.html to get started.

It is appreciated if feedback of the following is provided:
1. Are you able to create a single address?
2. Are you able to sweep private key?
3. Are you able to lookup the address on the testnet blockexplorer?
4. Are you able to send funds to the testnet address?
5. Are you able to scan the QR code with the android/blackberry testnet wallet?
6. Are you able to create bulk addresses?

There is no warranty and no party shall be made liable to you for damages. If you lose coins due to this app, no compensation will be given. Use this app solely at your own risk.

Warning:
For Bulk Wallet we recommended using Google Chrome, it's the fastest.
Requires IE9+, Firefox, Chrome or sufficient JavaScript support.
Mobile Safari only works with iPhone4 or newer devices. Older devices timeout while executing JavaScript.
DO NOT use Opera Mini it renders JavaScript output server side, therefore they might record the private key you generated.
BIP38 most likely will not work on mobile devices due to hardware limitations.

An update in 4 hours ( based on clock on GRS website). Any information about projects or does someone know what we can expect about this update?

I'd be pleased to read a little report on this, yes.

Hey, elcha. You'd do best to ask this question on the Telegram channel.

And Merry Christmas

when are the renewals?

How do i mine this coin? what miner is people using?

seems GRS will be 10USD soon

So what is the difference between the two? And what is an example of a "privacy coin" in your mind?

Just sold all my GRS.
After speaking to devs on Discord, it has been concluded with certainty, GRS is NOT a privacy coin.
They merely have privacy features.   

impressive features, nice combo of two great projects. now testing ...

This looks amazing, great news!

GRS Samourai Wallet gives you the privacy you want -
No need for Verge, PIVX or Monero:

https://twitter.com/SamouraiWallet

Hi guys, looked at the groestlcoin webpage, features, wallets etc. and I think this coin has a bright future. The competitors might be vertcoin and verge. Best regards and hoping GRS will fly !
