Heimdall Android

WARNING: Under development. Don't use the application with real funds! Application right now targets the Rinkeby test network. Switching to mainnet (or any other ethereum network) can be done by the user but it's its responsibility in doing so.

Goal

The goal of this project is to provide a 2FA-enabled Ethereum Wallet. This can be achieved by using the new Gnosis Safe (the new version of our Multisig Wallet).

You can add multiple devices to the safe and secure your wallet by requiring a set of devices to confirm each transaction. Depending on you security setting and number of devices you can still access your funds even if you loose access to a device.

Deploying and interacting with your Gnosis Safe will also be much cheaper than with our Multisig Wallet.

Roadmap

Current Features

• Deploying and Restoring Safes
• Creating and restoring account access (via mnemonic phrase)
• Transfer funds (ether or tokens)
• Address Book (so you don't need to memorize all addresses)
• Manage Tokens - verify token addresses that you trust so you can access their information easily
• Mnemonic reveal for active account
• Fiat prices for transaction costs (USD)
• Fingerprint support
• Add/Remove owner from deployed safes

To be added

• Trezor support
• Transaction scanning with QRCode
• Integration with external protocols/apps for signing

Setup

Infura

The Json RPC depends on Infura. You need to get an API key and create a file named project_keys with the following contents:

INFURA_API_KEY=<YOUR_API_KEY>

Replace <YOUR_API_KEY> with the key that you get from Infura.

Fabric

This project is integrated with Fabric by default so you need to create a file named fabric.properties inside the app module with the following contents:

apiSecret=<YOUR_FABRIC_API_SECRET>
apiKey=<YOUR_FABRIC_API_KEY>

Replace each field with the respective information (found in Fabric).

If you don't want to setup Fabric for this project you can follow the steps present in this page to disable the integration. We will improve this integration in the future so it can be easily enabled/disabled

Firebase

Heimdall uses Firebase and your build will fail if you don't have the google-services.json file.

This file can be found in the Settings page of the Firebase project.

After getting access to the file, move it to the app module.
