About Lesson

Welcome to this brand new course about blockchain. In this course, and in the upcoming ones, we will make you familiar with everything you need to know about blockchain. We will also teach you some of the latest blockchain coding skills so that you can enter the fascinating world of decentralized applications.

In this video, we will learn about ERC-20 token smart contract. The general idea behind the “ERC20Token” smart contract is to provide a standardized implementation of a fungible token on the Ethereum blockchain. This contract allows for the creation and management of tokens with a specific name, symbol, decimals, and total supply. Users can transfer tokens from one address to another, and the contract ensures that the sender has sufficient balance. It also includes functionality for approving and managing allowances, which allows third-party addresses to spend tokens on behalf of the token owner within a specified limit. By adhering to the ERC-20 token standard, this contract enables interoperability and compatibility with various decentralized applications (dApps) and exchanges within the Ethereum ecosystem.
