fantom-foundation/fantom-mobile-app

Mobile wallet and payments application for Fantom Opera chain. Deprecated in favour of Fantom-PWA-Wallet.

Fantom Wallet

Introduction

This is the repository for the Fantom Wallet mobile application.

Technology Stack

• React v16.4.1
• React-Native v0.56.0
• Redux v4.0.0
• react-navigation v2.11.2

Installation

You will need Node.js, Watchman, the React Native command line interface, and Xcode.

Node, Watchman We recommend installing Node and Watchman using Homebrew. Run the following commands in a Terminal after installing Homebrew:

brew install node@10
brew install watchman

The React Native CLI Node.js comes with npm, which lets you install the React Native command line interface.

npm i react-native

Alternatively, you can use yarn:

yarn global add react-native-cli

Setup

• git clone https://github.com/Fantom-foundation/fantom-mobile-app.git
• cd FantomWallet

npm install
npm run jetify

Alternatively, use yarn:

yarn install
yarn run jetify

iOS SETUP

Xcode

The easiest way to install Xcode is via the Mac App Store. Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.

run on iOS using command

react-native run-ios

or you can run directly from xcode.

ANDROID SETUP

1. Download and install Android Studio

Android Studio provides the Android SDK and AVD (emulator) required to run and test your React Native apps.

• Android Studio requires the Java SE Development Kit(JDK), version 8. You can type javac -version in a terminal to see what version you have, if any.

$ javac -version
javac 1.8.0_111

• The version string 1.8.x_xxx corresponds to JDK 8.

2. Install the AVD and HAXM

Choose Custom installation when running Android Studio for the first time. Make sure the boxes next to all of the following are checked:

> Android SDK
> Android SDK Platform
> Performance (Intel ® HAXM)
> Android Virtual Device
> Then, click "Next" to install all of these components.

• If you've already installed Android Studio before, you can still install HAXM without performing a custom installation.

3. Install the Android 6.0 (Marshmallow) SDK

Android Studio installs the most recent Android SDK by default. React Native, however, requires the Android 6.0 (Marshmallow) SDK. To install it, launch the SDK Manager, click on "Configure" in the "Welcome to Android Studio" screen.

For more detail visit: https://facebook.github.io/react-native/docs/getting-started

4. run using command

react-native run-android

Running on Device

To run the app on device, please follow instructions here

fantom-mobile-app's Issues

I should be able to copy address by clicking on text of address

Make it so I can easily copy the address when I select the text:

Remove from "Fees" screen

Test transfers on Testnet and wallet functionality

Here is the genesis account for the testnet with some existing FTM testnet coin:

Pub: 0xFD00A5fE03CB4672e4380046938cFe5A18456Df4
Priv: 50c4bf4dde1f383a172f52cb4624f089f685e67e00c6741a3ae03826c99cf082

You should first go through wallet creation process (which already exists) then transfer coin from the account above to that address (testing the transfer function) then you can test transferring between different wallets on different phones.

Thus, you should have working:

1. Testnet transfers, and

2. Ability to add wallet accounts to the testnet.

Is there anything else I'm missing?

Change text for "Captcha Verification"

"Please enter the corresponding phrases out of the 12 back-up phrases shown previously (from left to right)"

Merge latest code to master

Address Book Functionality

On the "Address Book" screen, i.e:

After payment is send to an address, save that address in the address book (i.e use AsyncStorage, so save the data onto the phone itself). You save a name to be associated with that particular address, but the name won't be save onto the blockchain, but into the phone itself.

You can also manually add to the address book:

And save to AsyncStorage too.

QR Code Scanning?

Change Fantom logos

The white and black logos should be the following:

Black:

White:

redirect to create wallet screen if not wallet is present

if no wallet private key can be found ie.

  getMasterKey() {
    const masterKeyTest = AsyncStorage.getItem('masterPrivateKey');
    console.log('getMasterKey');
    console.log(masterKeyTest);
  }

Returns False , the redirect to createWallet screen to create a new wallet.

If it returns True, redirect to home screen.

Round to 4 decimal places

Whenever we are displaying FTM amount.

QR Code scanning of desktop app qr code does not work

Add validation for checking wallet address (EIP-55)

Integrate the following check from the EIP-55 standard:

https://ethereum.stackexchange.com/questions/1374/how-can-i-check-if-an-ethereum-address-is-valid

/**
 * Checks if the given string is an address
 *
 * @method isAddress
 * @param {String} address the given HEX adress
 * @return {Boolean}
*/
var isAddress = function (address) {
    if (!/^(0x)?[0-9a-f]{40}$/i.test(address)) {
        // check if it has the basic requirements of an address
        return false;
    } else if (/^(0x)?[0-9a-f]{40}$/.test(address) || /^(0x)?[0-9A-F]{40}$/.test(address)) {
        // If it's all small caps or all all caps, return true
        return true;
    } else {
        // Otherwise check each case
        return isChecksumAddress(address);
    }
};

/**
 * Checks if the given string is a checksummed address
 *
 * @method isChecksumAddress
 * @param {String} address the given HEX adress
 * @return {Boolean}
*/
var isChecksumAddress = function (address) {
    // Check each case
    address = address.replace('0x','');
    var addressHash = sha3(address.toLowerCase());
    for (var i = 0; i < 40; i++ ) {
        // the nth letter should be uppercase if the nth digit of casemap is 1
        if ((parseInt(addressHash[i], 16) > 7 && address[i].toUpperCase() !== address[i]) || (parseInt(addressHash[i], 16) <= 7 && address[i].toLowerCase() !== address[i])) {
            return false;
        }
    }
    return true;
};

Search "Address Book" Functionality does not work

When you click "all" it should input in the "Price" field the whole balance you can transfer

Sending does not work

Getting this error:

Some error occurred when selecting “all” to send

Change "Available" to "Available to Transfer"

Remove "(1,000\ = 1.00002312FTM)", alert bell on top left, the donut icon to the left of the settings icon

"Billing Amount" not working for Facebook Messenger

Billing amount on QR code should never show "undefined"

"Change from "FP" to "FTM"

Save public, private and master private key to storage

Address name should be editable

Display something where it says “no transactions” (save details locally for now?)

Add a "send" icon for each address book entry

So when you click on it, will redirect to "send" screen with the "address to field" already populated:

https://www.dropbox.com/s/4k0tlqxytplstbv/Screenshot%202018-08-29%2019.11.16.png?dl=0

Text should be "Please check if the above information is correct."

Only valid numbers (including decimal points) should be valid

This should not be allowed:

"Add Contact" Does not work

Leads to

Add push notifications

Every time payment is received.

Scanning QR Code crashes app

When I try to scan a QR Code using the QR Code scanner. the app crashes and exits.

Please fix asap.

Should be “Favourites”

Implement endpoints to new testnet

I need you to connect the app also to the new testnet endpoints.

Please see the following documentation:

// node.js
const axios = require('axios');

const EthereumTx = require('ethereumjs-tx')
const privateKey = Buffer.from('50c4bf4dde1f383a172f52cb4624f089f685e67e00c6741a3ae03826c99cf082', 'hex')

const txParams = {
  nonce: '0x00',
  gasPrice: '0x09184e72a000',
  gasLimit: '0x27100',
  to: '0xFD00A5fE03CB4672e4380046938cFe5A18456Df4',
  value: '0x00',
  data: '0x',
  // EIP 155 chainId - mainnet: 1, ropsten: 3
  chainId: 1
}

const tx = new EthereumTx(txParams)
tx.sign(privateKey)
const serializedTx = tx.serialize()
const hexTx = '0x' + serializedTx.toString('hex')

axios.post('http://18.221.128.6:8080/sendRawTransaction', hexTx)
.then(function (response) {
  console.log(response.data);
})
.catch(function (error) {
  console.log(error);
});

I need you to implement for transfers.

Thanks,

Viewing ETH balance not working and transaction list not working

All Etherscan APIs can be found here: https://etherscan.io/apis#accounts

View ETH Balance: please follow "Get Ether Balance for a single Address".

View transaction list: please follow "Get a list of 'Normal' Transactions By Address"

Add recovery wallet functionality from seeds

1. Create a new screen based on existing designs that requires you to input 12 words in order (the mnenomic phrases).

2. Take the inputted words, and generate a new seed:

        menmonicPromise.then((mnemonic) => {
            const seed = Bip39.mnemonicToSeed(mnemonic); //creates seed buffer
            const mnemonicWords = mnemonic.split(' ');
            this.setState({
                mnemonicWords,
                seed: seed,
                loading: false
            })
        });

3. Follow the HD wallet creation process as before, i.e:

  walletSetup() {
    if(!this.checkValidation()){
      return;
    }
    const root = Hdkey.fromMasterSeed(this.state.seed);
    const masterPrivateKey = root.privateKey.toString('hex');
    const addrNode = root.derive("m/44'/60'/0'/0/0"); //line 1
    const pubKey = EthUtil.privateToPublic(addrNode._privateKey);
    const addr = EthUtil.publicToAddress(pubKey).toString('hex');
    const address = EthUtil.toChecksumAddress(addr);
    const key = {
      'root': root,
      'masterPrivateKey': masterPrivateKey,
      'addrNode': addrNode,
      'pubKey': pubKey,
      'addr': addr,
      'address': address
    };

    const hexPublicKey = EthUtil.bufferToHex(pubKey)
    // Save masterPrivateKey to device DO NOT USE IN PRODUCTION
    this.saveMasterKey(masterPrivateKey, hexPublicKey);
    this.props.setMasterPublicKey(masterPrivateKey, hexPublicKey);
    // Save pubKey generation
    // this.savePublicKey(pubKey);

    this.props.navigation.navigate('HomeScreen');
    /*
       If using ethereumjs-wallet instead do after line 1:
       const address = addrNode.getWallet().getChecksumAddressString();
    */
  };

Remove "122,000\", change text

On the screen below:

Remove "122,000"

Change text from "(The wallet will show you recent transactions)" to "(Your recent transactions will be displayed here)"

QR Code and text below should contain public key, not private key

The above looks like my private key.

My private key should not be viewable on the app anywhere!

Fix `estlint app` errors

Please fix all lining errors identified by running eslint app:

✖ 545 problems (545 errors, 0 warnings)
  314 errors and 0 warnings potentially fixable with the `--fix` option.

"Billing amount" should state "FTM" as well

For example, instead of just "Billing amount: 500" it should be "Billing amount: 500 FTM".

Documentation on developer app installation on own iOS and Android Devices

Please add documentation on how a developer can install the app on their own devices, i.e iOS and Android.

all field text should be lower case

When I type into each text field, the first letter is already capitalised, and hence the phrase does not pass.

It should always be lower case by default.

Change text for "Secret Mnemonic" screen

"Please write down this new mnemonic, and keep it secret."

Remove "All previous mnemonic will become invalid."

"You may lose your account if your mnemonic is known by others."

Mnemonic formatting on iPhone X and all phones needs to be 3 columns long

Make sure all code, like functions, are commented.

Add "sendTransction" Functionality to "send" screen

For the "Send" screen:

Please get the following to work with it:

  transferMoney (from, to, value){
    Web3.eth.sendTransaction({
    from: from,
    to: to,
    value: Web3.toWei(value, "ether"),
    }, function(err, transactionHash) {
        if (err) {
            console.log(err);
        } else {
            console.log(transactionHash);
        }
    });
  };

"Address Book" delete functionality not working

Ether Balance does not show on main screen

I recently received 1 Ether (From this Ropsten Ethereum Faucet) as show in this transaction: https://ropsten.etherscan.io/tx/0x9b6e5c0b6eb1245416591e22def071bf921766fd07e9803b8eb0f80113750436

However it does not display on the mobile app:

"Address Book" Favourite functionality does not work

QR Code Scanning?

How can I scan a QR code?
