Explore how decentralized apps cut out the middleman by enabling direct payments to service providers, using Uber and DEXs like Uniswap as real-world analogies.
Welcome to the beginning of our journey!
Now that you've gone through the fundamentals it's time to get our local environment set up and dive right in!
Attached to this note you will the final project code solution.
Please feel free to use the final code project if you get stuck somewhere and you've already exhausted our Online Discord Community and you need a reference. Remember, the node modules are not downloaded and you will have some configs if you want to get it working and check, but all the final code is attached fresh from the project that I've coded along with you from beginning to end and have it running nicely.
Again, my advice however is not to spoil the real effort here and just keep building and just keep this under your belt BUT please feel free to do as you please because we all have our own time commitments and personal goals, that being said!
Alright, so our KryptoBirdz NFT Marketplace await us and a brand new future internet unknown lies before our path ahead. There is no time like the present ;)
Good luck with your work and I'll see you in the next lesson!
Open the NFT marketplace project, review the folder structure and dependencies, and explore ERC-721, IPFS, and Hardhat setup as you prepare to connect to Polygon.
Set up MetaMask, create a Polygon account, and securely handle a private key in a Hardhat project. Connect to Polygon Mumbai and prepare NFT market and NFT contracts with OpenZeppelin.
Fetches unsold NFT market items by iterating token IDs using the market token struct, unsold item counts, and owner checks, returning the unsold items.
Style the dapp ui with layered css rules, hover transitions, and a background, then build a navigation bar linking to the marketplace, mint tokens, tokens minted, and the account dashboard.
Debug the front end of a React NFT marketplace by loading and displaying minted tokens, fixing a length typo and max width, and validating the buy flow with MetaMask.
Create a my NFTs page that loads the current user's owned tokens via Web3Modal, uses a signer to fetch NFT data, and displays price, image, name, and description.
Conclude by minting and listing tokens in a fully functional NFT marketplace, demonstrating buy/sell interactions, viewing minted assets, and configuring deployments from local to the Mumbai testnet and beyond.
Learn full stack DApp Development by building out from scratch to completion an NFT Marketplace (for minting, buying and selling NFTs live with IPFS data hosting) onto Polygon as a layer 2 Ethereum Solution using the best modern tools and languages.
Join in early on an revolutionary technology implementing global changes to multiple industries and businesses with DApps.
This is the course you've been looking for to get the full picture and functionality for DApp development and what it takes to succeed from testing to successful deployments and upgrades. Are you interested in writing your own Smart Contracts in the context of building a complete DApplication with NextJs and Ethers?
Do you want to learn about Hardhat and Infura, very powerful DApp development tools for connection blockchain to the front end? Do you prefer as a learner to jump right into project and save valuable time by building along a project and advancing your knowledge by being hands on? If so, then this is perfect course is for you!
In this course we build a complete NFT Marketplace DApp from start to finish. Every line of code we write is coded out live in real time and explained (we even go deep into the libraries and frameworks and connect the dots). We start off by installing and initializing everything we need to build a DApp with a local development environment and run through each dependency and library and break it all down. Once we're nice and warmed up, we immediately dive into demonstrating and reverse engineering a fully functional NFT Marketplace example from Nader Dabit.
What you will learn in this course:
Setting up the DApp development environment
Create a Nextjs app using the create-next-app utility to recompose the React library
Compile and Deploy Smart Contracts to Blockchain with Hardhat functionality
Implementing industry standard NFT smart contracts for DApps with the ERC721 OpenZeppelin Contracts
Using functional programming to maintain DApp state
IPFS data hosting with Infura Blockchain Suite Project Management
Implementing an NFT Minting form on the front end to lock in Metadata and Files for the DApp
Looping, iterating, and filtering through hash tables with Javascript and Solidity
Modern Card Design and UI with Tailwind and CSS
Hooking up a web3 provider to the Polygon and Ethereum network
Running full unit testing with Chai
And much more along the way!
Course Set up and Tools
This course develops its DApp project and source code with Visual Studio Code, a free (and pretty sweet) text editor for code. You can of course use your preferred IDE and any operating system you like... well as long as it's either Max OSX, Windows or Linux.
Is this the right course for you?
This course is straight to the point, time sensitive, and focuses on completing the project at hand (the reasons and explanations for the code and how it works) as the primary. Pretty much all of this course in its entirety is just building out our DApp NFT Marketplace and stopping to explain the techniques and library connections along the way. If you are the type of person who gets the most out of learning 'by doing', then this course will be for you.
It's important to please note that we do not start from zero coding knowledge. While you can jump in with beginner or intermediate skill level, you will need to have some basic JavaScript, web development and blockchain knowledge (please see my complete Solidity Course from Zero to Expert if you wish to start at the very beginning). If you have web development experience with other frameworks and languages besides React or JS then you should be fine as well. This course is essentially a demonstration on all the modern tools and patterns required to build a successful Dapp that you can then easily deploy on Blockchain's main network.
