In this video, we will learn about ERC721 Standard smart contract. The ERC721 standard is a set of rules and guidelines for creating non-fungible tokens (NFTs) on the Ethereum blockchain. ERC721 stands for "Ethereum Request for Comments 721," and it specifies the interface and behavior that NFT contracts should follow to ensure compatibility and interoperability. Unlike fungible tokens (such as cryptocurrencies), NFTs are unique and indivisible digital assets that represent ownership or proof of authenticity of a specific item, such as artwork, collectibles, or in-game assets. The ERC721 standard defines functions for token creation, ownership transfer, querying token metadata, and managing approvals for delegated token transfers. It enables developers to create and interact with NFTs in a standardized way, facilitating the development of NFT marketplaces, decentralized applications (dApps), and other NFT-related services on the Ethereum network.

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 NFT smart contract. The general idea behind the "MyNFT" smart contract is to provide a basic implementation of the ERC721 non-fungible token (NFT) standard. The contract inherits from the ERC721 contract and includes functionalities for creating and managing NFTs. It uses the Counters library to generate unique token IDs and keep track of the current count. The contract allows users to create an NFT by calling the "createNFT" function, which mints a new token, assigns it to the specified recipient address, and associates a token URI (Uniform Resource Identifier) with it. The token URI can be used to retrieve metadata ...

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 Openzeppelin smart contract. The general idea behind the "MyToken" smart contract from OpenZeppelin is to provide a standardized implementation of the ERC20 token standard. It inherits from the IERC20 interface and includes all the necessary functions and mappings required for managing a token's balances, allowances, transfers, approvals, minting, and burning. The contract utilizes the SafeMath library to prevent overflows and underflows in mathematical operations. It allows users to create a custom token by specifying its name, symbol, and decimals. The contract maintains a mapping of token balances for each address and enab...
