While Bitcoin cryptocurrency is revolutionizing online payments, Ethereum is now ready to revolutionize any industry that deals with data or transactions of any kind:

• Banking and payments
• Cybersecurity
• Supply chain management
• Networking and IoT
• Forecasting
• Insurance
• Private transport & ride sharing
• Online data storage
• Charity
• Voting
• Government
• Public benefits
• Healthcare
• Energy management
• Online music
• Retail
• Real estate
• Crowdfunding

All the blockchain-based systems such as Bitcoin or Ethereum are software. In order to start using Ethereum, a wallet along with an associated address is required. Once this is in place, a dispatched transaction can be broadcast to the network, where “miners” verify it and add it to the transaction history.

Using Appery.io with Ethereum

Naturally, it’s quite easy to use Appery.io to build a hybrid app hooked up with Ethereum. It just takes a few simple steps to build the wallet and ready the Ethereum setup.

First things first. In order to do anything on an Ethereum network you need to create an account. There are various ways to go about this, but the simplest one, suggested by Ethereum developers, is through the command line tool. Once this is done, a public key and a private key are issued. The public key is your unique address on the network.

After that, if you want to go with your own cryptocurrency, you need to build a smart contract using the command line. This produces a unique smart contract address. Also, make sure that you manifest enough of your own coins on your smart contract.

Next, the easiest way to develop the wallet app is to leverage the Appery.io API Express Ethereum component. With Appery.io, a citizen developer can concentrate on innovation not infrastructure to build the wallet app. The wallet is a two-page app. The first page shows the current balance in various cryptocurrencies as well as a list of transactions. The second page executes transactions. In addition, a sign-in page can be introduced to address security issues. Under the hood, the Appery.io API Express Ethereum services (built into the component) consume the aforementioned account and contract addresses to do the job.

Then, you need to top up your account to start testing the wallet app. In order to obtain free test Ethers, please go to faucet.rinkeby.io.

Finally, start the wallet app. Voilà! Now you are ready to send and receive cryptocoins.
