07.09.2019: Updated to version 0.6.1. Changelog.
This application is not yet published on Google PlayStore, and Android may warn that the signature is not trusted. Most likely you will have to allow installation from untrusted sources in your phone's Settings.
For the application to work, you must have security enabled on your phone - PIN code, fingerprint or another method of blocking unauthorized users from just opening and using your phone.
When you have installed SIGBRO on your Android phone and you open it for the first time, you'll have to swipe through a few presentation screens, and then you'll see this:
Tap the globe to select a language (English is the default).
Or tap the START button to move on to this screen and get started:
SET PIN lets you pick a PIN code that lets you access the app.
Enter your chosen PIN twice.
If your phone supports FINGERPRINT or FACE ID you can use that instead.
QUICK TOUR will show a small overview of what the Sigbro app is about.
Now it's time to scan or enter your existing Ardor account passphrase or register a new Ardor account.
Now pick an option:
I recommend you to set up Ardor account QR codes with SIGBRO OFFLINE.
Download it and use it in an offline environment.
Print the paper wallet, encrypt the passphrase and save it on a USB device.
Scan the passphrase QR with SIGBRO app. If you already have an Ardor account passphrase, you can use SIGBRO OFFLINE to quickly generate the QR code.
For test purposes you can access an online version of the app here ... yeah, that sounds rather paradoxical.
If you already have an Ardor account, you can also manually enter your passphrase into the app. This will only work if your account has a public key.
The SIGBRO app can generate a new account for you.
We do, however, recommend you to use SIGBRO OFFLINE if you have access to a pc. Simply because it makes your life simpler. You don't have to write a long passphrase several times. You just get a QR code to scan. Backing up your passphrase as paperwallet is easier when you can print it. You should NEVER copy-paste an Ardor passphrase and send it anywhere in plain text from your Android phone.
But you decide.
Tap the 'I DON'T HAVE AN ACCOUNT' button in the SIGBRO app.
Tapping 'CREATE ACCOUNT' will generate your private passphrase for you:
Make sure to write it down, EXACTLY as it is shown. You will need it already in the next step.
This is the decentralized blockchain, not some Facebook app, where the company behind stores all information for/about you. If you lose the passphrase, nobody can send you a copy. You will lose your access to the account forever.
Please understand that your Ardor account's passphrase is all that is needed to get full access to your account, and anything in it, and that the creators of the SIGBRO app cannot see, cannot access, and cannot keep a backup of your passphrase for you. The SIGBRO team cannot be held responsible if you lose your secret passphrase.
So DID you do what you were supposed to do? Good, hit VERIFY.
If you didn’t back up the passphrase, you will get no further with this app. There are back buttons of course.
Enter the word that the app suggests, and remember: lower case. An Ardor account passphrase is EXACTLY what you were shown. Now, we have done everything we can to help you protect you against yourself 😉
When you have entered the correct word and hit 'VERIFY': Congratulations!
You are almost done setting up the SIGBRO app, only a few things left:
On the last setup screen you are given the following choices:
1. You can sign up for receiving updates and transaction alerts:
It's an attempt to make your life easier. If you enter an email address, you will receive ONE guide on how to use the app. And then an email every time your Ardor account has an incoming/outgoing transaction. It can be payments, forging rewards, messages you get on the blockchain, dividends you receive, new incoming orders if you run a shop on the Marketplace, etc. Finally, Nxter.org will keep you updated with news about SIGBRO, relevant airdrops, bonuses, and the Ardor blockchain platform. You can opt-out at any time if you don't find the emails relevant.
2. FAUCET: New accounts can get funded (service sponsored by Jelurida):
By ticking this, a smart contract will announce your new Ardor account to the blockchain network (which adds security to it and makes it appear in blockchain explorers), and pay the ARDR fee it costs. You will also get a few IGNIS tokens so you can start using the Ardor platform. The faucet is only for NEW accounts.
Notice that only 1 account per device gets funded. So, if you create an account for testing purposes only, save the faucet for your real account. You can opt-in later - but you can’t opt-in twice. So, if you plan to take SIGBRO for a test ride, I recommend you to switch the app to testnet (in the Settings menu inside the app) and use the testnet faucet on ardor.world instead (testARDR faucet, testIGNIS faucet).
3. Finally - agree to the Terms and Conditions.
Now you can start to USE SIGBRO.
SIGBRO keeps the private key to your Ardor blockchain account safely encrypted.
SIGBRO does not collect private information. We register which Ardor accounts use SIGBRO. We do not collect your phone number, IMEI (your device’s unique serial number), email address, or any other information that can be used to identify you, and we CAN not connect your account to the mobile device you use.
When you use the SIGBRO app to log in to online UI's, your IP address will sent to their server - if it’s a Nxter.org service then your IP is sent to Nxter.org’s servers. If you log in to a website hosted by XYZ, then the XYZ server will get your IP address. You can always hide your IP by using a VPN.
Public blockchains (like Ardor's) are pseudonymous by design. If you link your Ardor account to your identity, all transactions from that account will be linked to your identity. It is up to you to decide whether that's a good or a bad thing for you. The SIGBRO Team (or me personally, at least) promotes and supports the idea of using Ardor accounts as Digital ID with all the benefits that will bring, but we don't make decisions for people - only software.
The SIGBRO app lets you import or create accounts, and use them to log in to wallets, clients, and services, register with membership sites, and prove ownership of your account without ever entering your account's passphrase. Kind of like you can log in with Twitter, Facebook, and Google accounts, but with Ardor you have tokens in your account too, and advanced blockchain features, a full economical framework on blockchain, and complete control over your funds and actions.
The SIGBRO app lets you sign transactions. You can set them up on any SIGBRO-compatible local client or website, and the SIGBRO app always lets you review the transaction details before you sign. You can make payments, cast votes on the blockchain, sign documents, or upload and timestamp files in the blockchain. We aim to make it easier to access and use Ardor's extensive feature-set for both non-tech people and developers.
What you do on the blockchain is registered on the blockchain and forever trackable to the account you use. What you do is YOUR responsibility. SIGBRO only provides one of more ways for you to use your Ardor account and sign transactions that you, yourself, set up, check, and confirm - nobody but YOU can see or control your account, or any transaction you make from your account, before you send it. The SIGBRO team is not responsible and can not be held responsible for any transaction you make on the Ardor blockchain or any of its child chains.
