Learn how to implement an NFT marketplace (Ethereum, Polygon) using jQuery.

Web3 development, where to start? 🤔 From knowledge content to practical coding, to create a solid Web3 infrastructure with more developers, DSRV provides guides on various mainnets and smart contracts. Web3 dApp and contract development, which was difficult to start because of the difficulty in finding information, now let's learn step by step with Dev Playground! 👩‍💻

We will give you a complete understanding of the entire Dapp development process, from setup to smart contracts and actual web production.

This course uses the Klaytn blockchain, created by Ground X, a subsidiary of Kakao. It covers the content required to create decentralized apps with Klaytn and introduces Klaytn's development ecosystem, including how to use the blockchain SDK (e.g., caver-js) provided by Klaytn.

This course is a hands-on practical session where you will build your own NFT marketplace using Solidity smart contracts, frontend technologies, and web3.js. Students will implement all marketplace features—from NFT minting to selling, buying, and deleting—and deploy them directly to the latest testnets: Ethereum Sepolia, Polygon Amoy, and Kaia Kairos. Additionally, you will learn how to use IPFS for the decentralized storage of NFT images and metadata, allowing you to experience a production-ready DApp architecture that goes beyond a simple demo. ✨ Key Features of This Course Full-Stack Learning: Covers React UI, smart contract writing, and multi-chain deployment all at once. Up-to-Date Environment: Supports Sepolia, Amoy, and Kairos testnets with MetaMask integration. Master the Core NFT Process: Image upload (IPFS) → Metadata creation → Minting → Marketplace trading. Practical & Hands-on: Gain real-world service development experience, including transaction handling, UX design, and multi-chain support.

Anyone can easily issue NFTs, even without programming knowledge. Anyone can easily issue NFTs, even without drawing.

You will learn how to create basic NFTs, buy and sell NFTs using React and Solidity (ERC721). You will learn how to write smart contracts and how to connect smart contracts written using React to the web.

In this course, you will learn the Solidity language for creating smart contracts.

Through this lecture, you will learn about the structure of the blockchain platform Klaytn and create a blockchain application (BApp) using the tool.

Sui is a layer 1 network that is friendly to both users and developers. It aims for wide usability through fast speed and low transaction costs. As an official education partner of Sui, Weldon Studio will guide you through the specific process of development and use through the network.

This course will teach you how to create your first smart contract and a simple voting dApp using Ethereum and Solidity.

This text lecture claims to be a 'Bible' and is a material that has tried to correctly contain such basic contents.
