Creating Klaytn Blockchain Applications - ERC721 Tokens

It's time to learn about Non-Fungible Tokens (NFTs). We will learn about the types of tokens used in blockchains and create a non-fungible app that digitally items YouTube thumbnails using non-fungible tokens (ERC-721) and allows you to buy and sell them with other users.

These NFTs have the potential to be applied to various industries because each token has its own unique characteristics and value. For example, in the gaming industry, tokenizing items can be used to clearly establish ownership, solve problems of duplication and forgery, and manage collectibles by digitally converting them into assets.

In the future, even certificates and personal data will be digitized, tokenized and managed through blockchain, and the era will come when ownership of digital assets will be clear.

3-line summary of learning objectives 📖

  • Using the payment function of the Klaytn blockchain and IPFS
  • Create ERC721 tokens and buy/sell smart contracts using Solidity
  • Complete your blockchain application by connecting it to the frontend (JavaScript & jQuery).

This will help these people 🔍

  • Developers interested in Clayton
  • For those of you wondering what a non-fungible token (NFT) is?
  • People who are sensitive to new technologies and trends

Kakao Clip Wallet also handles non-fungible tokens (NFTs).

    The course content is very good. However, it is very hard to follow because it is an old version. I am sweating because I have to modify it one by one to make it work, starting from webpack to caver-js, etc. ㅜㅜ Please update it.

      Drizzle was posted by someone else, so I corrected it. But what the hack? Even the most stubborn people achieved this on their own (or with the help of students who worked hard to find solutions for each lecture). The explanations for each method or contract in each lecture were good, but the effort to identify the problems was entirely up to the students. Programming classes are meaningful when they code themselves and the results shown in the lecture are consistent, and students will be satisfied only when they gain confidence to utilize them. Can you have a satisfactory course and results by downloading samples with many problems? There were no appropriate answers or solutions to the comments in the lecture, even though they were posted 1-2 years ago. Please think about it again and pay. The programs and libraries mentioned in this lecture have too many problems. 1. connect-privkey-to-provider(@truffle/hdwallet-provider module update due to installation) 2. webpack.config.js settings (fallback-related resolve settings, plugin webpack.ProvidePlugin settings) etc. 3. Other problems encountered while running truffle migrate, truffle compile, npm run 4. Execution problems caused by conflicts with various low-version modules written in package-json Compilation or deployment problems keep occurring and there is no solution for them. (In other words, program execution errors keep occurring.) They fool me with the preview sales that they will create non-apps and dapps, but they only show me the results with lots of errors, so it's frustrating and a waste of my money. There is absolutely no error check for this lecture. Those who are thinking of paying, please reconsider. There is no program that can be used through this lecture, and the program utilization for Klaytn IDE that appears at the very beginning is also on YouTube. I've been running npm and node for a week and reinstalling them, but nothing has improved. I'm just disappointed that other students are talking about the answers they posted as if they were their own solutions.

        Sorry. It must have been hard. You said it was a sales technique, but it is absolutely not a sales technique. This is a course that I made with all my heart and soul two years ago. I have organized all the solutions, so if you refer to it, I believe you will be able to persevere even if your development skills are minimal! Many people have already persevered recently.. I will answer. https://www.inflearn.com/questions/370615 By the way, is drizzleConnect a hack? I have never used it in my lectures... It seems that you took out your frustration on another lecture and took it out here. ------------------------------------------------------------------------------------------------------- Update I should have answered more sincerely as a beginner, but I was busy and left Inflearn for a year. I sincerely apologize to all the students for this. I started answering again two months ago, but I think it would have been better if the students had at least asked questions and left 1 point. I was willing to help you enough. If you leave a 1 point and say something that is not related to the course (drizzleContext), I have no choice but to respond, and since you recently revised your score, it seems like you left it impulsively. I decided that rather than going through the current situation and revising each problem one by one, I could help students faster by asking for help from someone who recently finished it. If you are disappointed with this, then there is nothing I can do. It is heartbreaking to think that it is a waste of money, but thanks to you, I think I will visit Infraon often to leave questions. And if you leave your account number, I will refund you directly.

        Thank you for the great lecture. It was good to learn the overall structure, Solidity, and how to understand and use Caver.js. There may be some parts that beginners may get stuck on, but you can complete the course if you look for them. Thank you for the great video, and I will check out the latest lecture soon.
