This article will walk you through writing and deploying a non-fungible ( ERC721 ) token smart contract using Ethereum and the Interplanetary File System (IPFS) .
The Interplanetary File System IPFS is a
实现文件的分布式存储、共享和持久化的网络传输协议. It is a content-addressable peer-to-peer hypermedia distribution protocol. The nodes in the IPFS network form a distributed file system. It is an open source project developed by Protocol Labs with the help of the open source community since 2014. It was originally designed by Juan Benet.
ERC721 is a smart contract standard interface for non-fungile tokens, (non-fungile tokens) non-fungile tokens are referred to as NFTs.
As NFT brings the blockchain into the public eye, more and more NFT-related applications are being implemented. And now is the perfect opportunity to learn more about NFTs by publishing your own NFTs (ERC-721 tokens) on the Ethereum blockchain!
In this article, we'll cover creating and deploying smart contracts Metamask、Solidity、Hardhat、Pinata 和 Alchemyon the test network using .GoerliERC-721
Step 1: Connect to the Ethereum network
There are many ways to make requests to the Ethereum blockchain, but to make things easier, we're going to Alchemyuse a free account on . Alchemyis a blockchain developer platform that allows us to communicate with the Ethereum chain without running our own nodes .
In this tutorial, we will also use
