Implementation of Ethereum Request for Comment (ERC20) Token

Abstract

Blockchain technology has been an essential aspect for research due to its, peer to peer nature, distributed nature, and decentralization, some of its applications are Supply chain, Healthcare System, Real state, etc. Ethereum is a distributed public blockchain network that focuses on running the code of any decentralized application. A smart contract is a computer program having self-verifying, self-executing, tamper-resistant properties. Initial Coin Offering (ICO) is a process similar to crowdfunding, in which companies raise funds from investors, who, in exchange receive tokens or digital assets. This paper deals by explaining the proposed model, different functions of ERC20 standard, the different tasks performed by each function and implementing various functionalities of ERC20 Token in Solidity.
