HOW TO CREATE ETHEREUM WALLET INSTALL
The site will look like this:ĭownload the installation package and install the app manually.
HOW TO CREATE ETHEREUM WALLET CODE
On Android, use a QR code scanner application, like QR Code Reader, to read the URL and visit the site. On iOS, use the native camera app to scan the QR code. Repeat this process for iOS if you work with Apple devices or want a cross-platform BETH transacting experience. After a moment’s wait, the build will finish, and a QR code appears: I’ve left the default information, but you can customize the package name here.
HOW TO CREATE ETHEREUM WALLET FOR ANDROID
To do so for Android (similar to iOS), navigate to your EthereumWallet project from within Service Studio, and tab over to Native Platforms:Ĭlick Configure Android App, which brings you to this next screen:
HOW TO CREATE ETHEREUM WALLET FULL
Unfortunately, Ethereum Wallet requires mobile plugins not provided through OutSystems One, so you must run a full build of this test application to have it work on your device. Then publish Ethereum Wallet to your environment. Under Site Properties > Token, paste your BlockCypher token from step 1 into the default text value for this site property, as shown below. Once installed, open the Ethereum Wallet module and navigate to the data tab. If one fails to install-the Mobile QRCode plugin, for example- download it directly from the Forge before you continue. During installation, Ethereum Wallet will also install several dependencies. Download Ethereum Wallet to OutSystemsĭownload Ethereum Wallet from the OutSystems Forge. To create a token, sign up for a free account at BlockCypher.īlockCypher generates your token immediately after account creation and displays it like so:Ģ. The app will run fine without a BlockCypher token but will prohibit users from sending/receiving BETH. To get Ethereum Wallet running on your devices, follow these steps. To receive BETH the app displays a QR code* address for the sender (also an Ethereum Wallet user) to scan using their camera. We solved this issue by supplying QR codes*, and that’s what I’ve done here. I didn’t expect a user to type all of that without making a mistake, and neither does the rest of the cryptocurrency world. To send BETH, the app needs to work with addresses that look like this: 7eb4b2757e4467498231128d8ea4eff1abff8d59. Their rules limit us to fund no more than 1 BETH at a time, and no test address can contain more than a total of 15 BETH.įor the interface, I provided four main screens: home, receive, send, and settings. For simplicity’s sake, the demo does not allow users to import existing credentials (but that functionality is possible).Īnd since this app uses BlockCypher’s test network, we can use their faucet to magically fund our wallets. On initial launch, Ethereum Wallet creates an address for the device and stores both the address and keys in the device’s native keystore.
My first step was to create an address for each user.
In it, you’ll find the ability to send BETH, receive BETH, check your balance, and more. I built a sample application, Ethereum Wallet, to leverage the BlockCypher network by incorporating the BlockCypher Forge component.

So if you plan to build such an application, consider putting extra thought into security and how to best educate users about their wallets and potential security threats. The end-user is ultimately the weakest security link. MyEtherWallet has an interesting approach: They provide a passphrase, a key store file, hardware wallet integrations, and a print backup that looks like this (don't worry, you won’t have to print anything for this demo).Īlthough MyEtherWallet does not keep any information about the wallets themselves (being a wallet creation and ETH transfer service), sophisticated phishing attacks with bad certificates managed to hack their way into user wallets. On the other, hyper security has led to lost wallet access due to misplaced passphrases. On the one hand, slightly relaxed security (e.g., 2-factor authentication using SMS codes) has led to hacked wallets.
The industry has written a lot about wallet security, but it looks like they’ve yet to reach a de facto standard. I've selected BlockCypher because it allows me to control my private keys and it provides a test network using BETH instead of ETH. Choosing an APIĬoinbase,, and BlockCypher allow you to create a wallet and send transactions through the respective blockchains. Specifically, a wallet to send and receive Ether ( ETH), the digital currency powered by the Ethereum project. Their design ultimately resembled a cryptocurrency wallet and it inspired me to create such a wallet using OutSystems. Recently, I've helped a bank build a POC payment system that works between customers.
