The header demonstrates the fact that a container is much more than just a GUI component:. This container might look simple at first with only a logo and a network selector. Does it even need to be in its own container? The answer is that in eth-hot-wallet every network communication-related action and state management is done inside the header container. More than enough for any container.

The modal includes some basic input verification, like amount and Ethereum address check. It does not use Saga. We separated it into a new container to reduce clustering the state of the homepage container. Token Chooser appears when the user wants to select what token the wallet will manage. Since the appearance of the ERC20 standard EIP20 , it was obvious that tokens were going to be an important part of the Ethereum ecosystem.

The Ethereum wallet was designed with a unified design approach in mind. Under the hood, the API for sending Ether and sending tokens is quite different. So is checking the balance, but they will appear the same on the GUI. To send Ether, we need to use native functions provided by the web3. More on this issue later. Using Redux store as a single source of truth greatly benefits the wallet. GUI actions and user-triggered flows can be relatively easily managed by actions and reducers provided by Redux.

Aside from keeping the UI state, the Redux store also holds the key-store object a partially encrypted JavaScript object supplied by eth-lightwallet. This makes the keystore accessible throughout the app by using a selector. Redux-Saga is what makes the entire setup shine. In the case of Ethereum wallet, by using Saga we get a comfortable way to handle asynchronous actions such as rest API calls, keystore actions, Ethereum blockchain calls via web3.

All the requests are cleanly managed in one place, no callback hell, and very intuitive API. When using eth-lightwallet, the password needs to be provided during the initiation of the hd-wallet. We can ask the user to confirm the password and the seed or generate a new set on its behalf.

Alternatively, we can ask the user for their own existing seed and password. Eth-hot-wallet implementation is based on the following code to generate random but human-readable strings :. After the user has accepted the password and the seed, we can use the values and generate the new wallet.

The lightwallet keystore vault JSON object is encrypted, and it requires from us an external passwordProvider to safely keep the encryption key. The keystrore object is always encrypted. The app is responsible for safekeeping the password and provides it with any action.

When the wallet is loaded for the first time, it will check if there is a keystore in local storage and will auto load it to Redux state if so. At this point, we can read the public data of the keystore but not the keys. To display public data before the user enters the encryption password, we need an additional operation mode: loaded and locked.

In this mode, the wallet will display the addresses and fetch the balances but will not be able to perform operations such as sending transactions or even generating new addresses. When using Web3. However, to properly integrate it into our saga. The Ethereum blockchain does not provide primitives that encapsulate token functionality, nor should it. Every token deployed on Ethereum is, in fact, a program that corresponds to the eip20 specification. Since the Ethereum virtual machine EVM is Turing complete with some restrictions , every token might have a different implementation even for the same functionality.

When we are sending a token on Ethereum, we are interacting with a smart contract. We will store the erc20 ABI as part of our JavaScript bundle and instantiate a contract during the program run-time:. After contract setup, we can easily interact with it programmatically using the Web3.

After the creation of contract instance, we can access the contract functions by calling the desired function straight from JavaScript:. See Web3. We will promisify the tokenContract. It is possible to use es6-promisify or similar instead of writing the promise directly, but I prefer the direct approach in this case. The example is provided by another project.

It is an important feature and should be used extensively. The new version of Web3. Enter the PromiEvent : A promise combined event emitter. This API is far more informative and elegant than the one provided with 0. We will see how we can integrate it into our web app with the help of Saga. The motivation is to update the application state Redux store once a change to the transaction state is detected. Once the channel and the handler are both ready and the user initiates the transaction, we need to register to the generated events:.

In fact, we don't need a new channel for each transaction and can use the same channel for all types of transactions. The full source code of this example can be found here. There are several ways to watch for blockchain changes. It is possible to use Web3. In eth-hot-wallet, the wallet is polling the blockchain periodically for balance changes and Coinmarketcap API for price changes. When building web apps using JavaScript and npm, it might be tempting to add new packages without analyzing the footprint increase.

Eth-hot-wallet uses webpack-monitor to display a chart of all the dependencies and the differences between each build. It allows the developer to see the bundle size change clearly after each new package is added. Webpack monitor also can help in finding the most demanding dependencies and might even surprise the developer by highlighting the dependencies that do little for the app but contribute a lot to the bundle size.

If someone obtains your seed phrase, they can take over your wallet. When you open the app, it will take you to the wallet interface. In the first tab, Wallet, you can see the balance of all available coins and your wallet addresses for different currencies.

You have the option to sort the tokens by volume or hide zero balances. In the Settings tab, you can change your password and store private keys securely in an encrypted form. You can also import an external wallet into the Atomic Swaps Wallet, but you have to enter a private key. You can also use the wallet to connect to another decentralized exchange or import external wallets.

We'll go over 4 features in this article and how to use them. For Ethereum:. A wallet address is 42 characters in length and always starts with the prefix 0x. This applies to all cryptocurrencies, not just Ethereum. Each time you create a wallet, you need to create a seed phrase. It usually consists of 12 random words in a particular order. Not only are the words important, but so is the order. Jot it down and place it somewhere for safekeeping. This is your one and only chance to set up your passphrase.

This phrase allows you to regain access to your wallet if you forget your password or get a new device and you need to re-download your wallet. You also need the phrase to activate your old wallet on your new phone or tablet. You should have created your seed phrase to transfer your wallet to another device. You must ensure your crypto is as secure as possible. Your wallet must have a private key to generate a public key and identify your wallet on the network.

You also need to store it in a safe place, like your seed phrase. Learn how to store it properly in our blog post. The public key is a hashed version of your private key only available for decryption in one direction and for one time. The public key is decrypted to show the private key and send funds to the correct address. This one-way encryption is called hashing, and it's the most prevalent form of encryption in the cryptocurrency world.

In the crypto world, fees are ever--present. Atomic Wallet has zero fees for exchanging, send,ing, or receiving cryptocurrencies. Ethereum is second only to Bitcoin, the first cryptocurrency.

A portion of these fees also goes to the miners verifying the transaction blocks. Ethereum has Miners receive rewards in Ethereum to keep mining. When Ethereum first debuted in , it had around 72 million tokens. That said, once Ethereum moves from Proof-of-Work to Proof-of-Stake , the number of new ethereum tokens created will dramatically decrease.

This, combined with proof-of-stake, will likely create a supply shock and push up the price. Please do your own research before you invest in any asset. In the Ethereum 2.
