The ERC token is developed on the basis of Ethereum. The platform consists of a blockchain that stores transactions, and a virtual machine that encodes smart contracts that guarantee their execution. The standard simplifies the creation of projects in a decentralized registry, optimizes the operation of the network. Coins based on the Ethereum blockchain are designed to represent a developed project or technology. This financial asset is created with the help of smart contracts. A company conducts ICO and issues a token for sale to investors and initial offering. The goal is to raise capital to launch and develop the project. The disposal of tokens, payment of commission for smart contracts are carried out for ETH or BTC, thus increasing the demand for these currencies. Standard ERC tokens are unified. They play the role of cryptocurrency, assets, and digital shares. It is important that they comply with the accepted address format. Token shares are profitable as they yield income in the form of dividends. In addition, the owner participates in the management of the company, controls the transfer and consumption of coins, keeps track how many assets are held on the accounts in the defined period. ERC - the official unified protocol, designed to solve the issue of compatibility of different coins and improve the functioning of the network. The standard token on the Ethereum blockchain is characterized by the following properties:. In addition, cryptocurrency experts from Soft-FX recommend using three functions for identifying coin parameters: symbol, name, and dimension. Smart contracts involve the use of additional functions. For example, empowering an investor to vote for a project. It can easily expand the functionality and add the right options for the project to the smart contract. It contains the information on compliance with the terms of the contract and the specified set of functions. It is prohibited to change or not to comply with the contract requirements. If a developer does not include all the standard parameters, compatibility with ERC and interaction with other functionality will be incomplete. The contract and related information can be found contained in the blockchain. Payments are performed automatically, and the blockchain protects transactions. The smart contract is not free of vulnerabilities. The mistake made at its development leads to the loss of means. An add-on is being developed to reject a transaction that does not meet the requirements of the contract. It is recommended to register and create a wallet on the official website.

General information about a token Coins based on the Ethereum blockchain are designed to represent a developed project or technology. Properties of the standard ERC - the official unified protocol, designed to solve the issue of compatibility of different coins and improve the functioning of the network. The standard token on the Ethereum blockchain is characterized by the following properties: Makes assets interchangeable; Used on compatible platforms, projects, exchanges; Ensures operation with compatible decentralized applications DApps ; Simplifies transactions with the receipt and sending of coins; Interacts with other currencies, smart contracts; The standard tokens based on the blockchain are decentralized and open source. Protocol Functions When creating a token and building a smart contract, there are 6 simple but obligate functions: Control of the initial number of coins and issue; Assignment of the initial quantity to the company's address and to the owner of the ICO; Sending assets to investors, recording the balance; Distribution of coins among users for transactions, verification of their movement; Checking the remaining balance; Control the adequacy of the currency at the address for transmission. The ERC standard has its pros and cons, as a large number of identical signs are created. Technical specifications of the smart contract Smart contract, written in the form of code, performs the following actions: Conducts transactions, transfers tokens; Confirms cost; Tracks account balance.

Ever since Ethereum was introduced in the blockchain space with its presence in , Vitalik Buterin, a Canadian-Russian programmer, has brought forth new decentralized applications dApps. Many people believe that smart contracts are a new concept and 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. Ethereum is also one of the blockchain platforms that can execute arbitrary code so that you can perform any program on Ethereum. The Ethereum Blockchain is a potential distributed infrastructure that facilitates you to complete projects using smart contracts. Before discussing how to create a smart contract on the Ethereum platform, you need to understand the Ethereum blockchain and how it runs smart contracts. 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. The functionality of EVM is restricted to virtual machines; for example, it cannot make delayed calls on the internet or produce random numbers. Therefore, it is considered a simple state machine. Writing programs in assembly language do not make any sense, so, Ethereum required a programming language for the EVM. 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. Solidity is a smart contract programming language on Ethereum. Developed on the top of the EVM, it is similar to the object-oriented programming language that uses class and methods. It allows you to perform arbitrary computations, but it is used to send and receive tokens and store states. It would be best to have a good understanding of Solidity programming language to efficiently write an Ethereum Smart Contract. Smart Contracts are the business logic or a protocol according to which all the transactions on a Blockchain happen. 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 and 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 deployed smart contract similarly at a particular address by entering the accurate data along with Ethereum to call the compiled and deployed Solidity function. It can also be defined as a collection of code stored in the blockchain network, defining conditions to which all parties within the contract should agree. We will be sharing the example of Ethereum smart contract creation using the Solidity programming language. So, it is first essential to understand what is Solidity. Solidity is a Javascript-like language developed specifically for creating smart contracts. It is typed statically and supports libraries, inheritance and complex user-defined types. Solidity compiler converts code into EVM bytecode which is sent to the Ethereum network as a deployment transaction. 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 ethers in your Ethereum wallet to deploy 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. It will ask you to create a password. After you create a password, it will send you a secret backup phrase 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. You should either write this phrase on a piece of paper securely or store it safely on an external encrypted hard drive where no one could find it. 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. You can add as many Ethers you want to the test network. Once the dummy ethers are added to the wallet, you can start writing smart contracts on the Remix Browser IDE in the Solidity programming language. The remix is the best option for writing smart contracts as it comes with a handful of features and offers a 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. 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 tokens will be stored in the wallet of a 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 would be able to see the number of tokens there. Steps to test an Ethereum smart contract Try to run all your smart contract methods like transfer, totalSuppy and balanceOf in the above smart contract example. These methods are present at the right-hand side of the remix window and you can run all the processes 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 running the totalSupply method. Steps to deploy Ethereum Smart Contracts To make your smart contract live, switch to the main ethereum network at metamask. Add some real ethers. Now again, deploy your smart contract using remix as mentioned in the above steps. Select your smart contract. Select the same compiler version that you selected at remix to compile your code. Click Verify. It will take a few minutes and your smart contract will be live if no issue occurs. You can now run your smart contract methods at Etherscan. Tools and Technologies required for implementing Ethereum Smart Contracts Truffle It is an Ethereum development framework that allows developers to write and test smart contracts. Written in JavaScript, Truffle contains a compiler for the Solidity programming language. Truffle Contract is a JavaScript library that allows importing of compiled smart contracts.
