Ethereum wallet tutorial
Many people believe that smart contracts are a new concept and were invented with the Ethereum Blockchain Platform. No use of artificial intelligence is implied. A smart contract is a set of promises specified in digital form, including protocols within which the parties perform on these promises. His work later inspired other scientists and researchers, as well as Vitalik, who developed Ethereum. Before we go deeper into the creation and deployment of the Ethereum smart contract, it is essential to understand the Ethereum platform and how it works. Blockchain platforms allow developers to create and run smart contracts.

Building A Crypto Trading Platform
Ever since Ethereum was introduced in by Canadian-Russian programmer, Vitalik Buterin, it has brought forth new decentralized applications dApps.
Many people believe that smart contracts are a new concept and have been invented with the Ethereum Blockchain Platform. However, they date back to when computer scientist, Nick Szabo, coined the term and defined them as:. No use of artificial intelligence is implied. A smart contract is a set of promises, specified in digital form, including protocols within which the parties perform on these promises. His work later inspired other scientists and researchers, including Vitalik.
Before we go deeper into the creation and deployment of an Ethereum smart contract, it is essential to understand the Ethereum Virtual Machine and Gas. The purpose of EVM is to serve as a runtime environment for smart contracts built on Ethereum. Consider it as a global supercomputer that executes all the smart contracts. As the name indicates, Ethereum Virtual Machine is not physical, but a virtual machine. In the Ethereum Virtual Machine, Gas is a measurement unit used for assigning fees to each transaction with a smart contract.
Each computation happening in the EVM needs some amount of gas. The more complex the computation is, the more the gas is required to run the smart contracts. Smart Contracts are the business logic or a protocol according to which all the transactions on a Blockchain happen. The general objective of the smart contract is to satisfy common contractual conditions. For example, if we want to create our own token on Ethereum, we need to develop smart contracts according to which all the calculations on our token would happen.
It is a stand-alone script written in Solidity, compiled into JSON, and deployed to a particular address on the blockchain. Just like we can call a URL endpoint of a RESTful API to run some logic through an HttpRequest, we can execute a deployed smart contract similarly at a particular address by entering accurate data along with Ethereum to call the compiled and deployed Solidity function.
Smart contracts can be deployed to the decentralized database for a fee proportional to the storage size of the containing code. It can be also be defined as a collection of code stored in the blockchain network, defining conditions to which all parties within the contract should agree upon.
Solidity compiler converts code into EVM bytecode, which is sent to the Ethereum network as a deployment transaction. Such transactions have more fees compared to smart contract interactions, and the owner of the contract must pay them.
MetaMask acts both as an Ethereum browser and a wallet. It allows you to interact with smart contracts and dApps on the web without downloading the blockchain or installing any software. Though MetaMask is currently available for Google Chrome browser, it is expected to launch for Firefox too in the coming years. Once it is downloaded and added as a Chrome extension, you can either import an already created wallet or create a new wallet.
You must have some amount of Ethers in your Ethereum wallet to deploy an Ethereum smart contract on the network. Install MetaMask in your Chrome browser and enable it.
Once it is installed, click on its icon on the top right of the browser page. Clicking on it will open it in a new tab of the browser. Click on Create Wallet and agree to the terms and conditions by clicking I agree to proceed further. It will ask you to create a password.
After you create a password, it will send you a secret backup phrase that can be used for backing up and restoring the account. Do not disclose it or share it with someone, as this phrase can take away your Ethers. Next, ensure that you are in the Main Ethereum Network.
The above networks are for testing purposes only; note that the Ethers of these networks have no real value. In case you want to test the smart contract, you must have some dummy Ethers in your MetaMask wallet. For example, if you want to test a contract using the Robsten test network, select it, and you will find 0 ETH as the initial balance in your account.
To proceed, you need to click request 1 ether from faucet and one ETH will be added to your wallet. You can add as many Ethers as you want in the test network. Remix is the best option for writing smart contracts, as it comes with a handful of features and offers comprehensive development experience. Open Remix Browser, and click on the plus icon on the top left side next to the browser to create a.
Select a version of the compiler from Remix to compile the solidity Ethereum smart contract code. Deploy the smart contract at the Ethereum test network by pressing the deploy button at the right-hand side of the Remix window. Wait until the transaction is complete. After the transaction commits successfully, the address of the smart contract would be visible at the right-hand side of the Remix window. At first, all the ERC20 token will be stored in the wallet of the user who is deploying the smart contract.
To check the tokens in your wallet, go to the MetaMask window, click add tokens, enter the smart contract address, and click ok. You should be able to see the number of tokens there. Published at DZone with permission of Akash Takyar. See the original article here. Thanks for visiting DZone today,.

Gas In the Ethereum Virtual Machine, Gas is a measurement unit used for assigning fees to each transaction with a smart contract.
What Is a Smart Contract? What Is Solidity? Download the MetaMask Chrome extension before you start writing smart contracts. Steps to Develop an Ethereum Smart Contract 1. For example, I have added one ETH in this scenario. It is usually used for writing smaller sized contracts. Syntax and error highlighting. Functions with injected Web3 objects. Static analysis.
Integrated debugger. Integrated testing and deployment environment. Deploy directly to Mist or MetaMask. Create a. Deploy Your Contract Deploy the smart contract at the Ethereum test network by pressing the deploy button at the right-hand side of the Remix window. Test an Ethereum Smart Contract Try to run all the methods of your smart contract like transfer, totalSuppy, and balanceOf in above smart contract example.
These methods are present at the right-hand side of the Remix window, and you can run all the methods from there itself. Try to transfer some tokens to other Ethereum wallet addresses, and then check the balance of that address by calling the balanceOf method. Try to get total supply by calling the totalSupply method. Add some real Ethers. Now, again deploy your smart contract using remix, as mentioned in the above steps.
Select your smart contract. Now you need to verify your smart contract here, click verify contract. Copy your smart contract code and paste it at Etherscan. Select the same compiler version that you selected at remix to compile your code. Check optimization to Yes if you had selected optimization at remix; otherwise, select No. Click Verify. It will take a few minutes, and your smart contract will be live if no issues occurs. You can now run your smart contract methods at Etherscan.
