React app that connects to user's Metamask wallet and creates an ERC721 "Composition" token containing a given string. In development. Created for educational purposes. In progress.

Git clone this repo locally.

Go to Remix IDE at https://remix.ethereum.org/ and create a new file Composition.sol. Copy-paste the code of the Composition.sol file from this repository. Deploy the contract on Sepolia Ethereum test network (I did not test on other networks, you can do it at your own risk). Then go to Composition.json file of this repo and change the details at the end:

"networks": 
{
	"<here number of the used Ethereum network, 11155111 for Sepolia>": {
		"address": "<here enter number of your newly deployed contract>" 
	}
}

Run: npm run build. This will update the build file of this repo (for more info see: "Getting Started with Create React App" below).

Host this app somewhere, for instance, you can quickly host it on netlify.app. Create an account, drag and drop the build file and it's done.

Go to your app at a given address from Netlify or other hosting page.

Create a new Metamask wallet (please don’t test my experimental app on your primary Metamask wallet, I take no responsibilty for your real finances)

Go to your new Metamask settings and allow visibility of test networks

Change your network to Sepolia.

Then, you need to get some free coins. You can mint some for free here (running this for 1 minute will be enough): https://sepolia-faucet.pk910.de/

Go to your app address, connect your Metamask wallet by clicking Connect Wallet. You will see your public hash key and your ETH balance available.

Enter some text and click Create composition (you can of course enter a link to a hosted, preferrably decentralised file, for example on IPFS)

Wait a little bit (even one minute) until you get an alert stating that you are now owner of the token.

Go to https://sepolia.etherscan.io and enter your public hash key, find the latest transaction and go to More details -> + Click to Show more -> View input as -> UTF-8. You will see your previously written text encoded in an NFT that you now own.

You can add the NFT to your Metamask wallet manually, by providing it the contract number and token number of your NFT.

This is a very quickly created repo, for demonstration purposes in a project, which might contain many bugs, for which I apologise. I intend to further develop this repo in the future, any recommendations are welcome.

This project was bootstrapped with Create React App.

In the project directory, you can run:

Runs the app in the development mode.
Open http:https://localhost:3000 to view it in your browser.

The page will reload when you make changes.
You may also see any lint errors in the console.

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

Note: this is a one-way operation. Once you eject, you can't go back!

If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.

You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.

You can learn more in the Create React App documentation.
