You can find the contract code in packages/hardhat/contracts/BatchGraduationNFT.sol. It's also available in the externalContracts.ts file in packages/nextjs/contracts/ (for front-end use in future issues).
Get your Batch Graduation NFT
1. Create your own branch
Before you begin, make sure you're working on a separate branch. Here's how:
Clone the repo to your local machine (If you haven't already)
Navigate to the cloned directory in your terminal.
Create a new branch using git checkout -b [your-branch-name]
💡 You'll notice that the dApp points to the Optimism chain. Check the scaffold.config.ts file to see how it's configured.
3. Understand the graduate Function

Check out the graduate function in the BatchRegistry.sol contract. After performing some validation checks, this function calls the mint function of the BatchGraduationNFT.sol contract to mint your NFT. Review the BatchGraduationNFT.sol contract to see how it works.
4. Set Up a Metadata Contract

You’ll need to deploy a Metadata Contract to set attributes (like color and name) for your personal NFT.
Create a Metadata.sol contract in packages/hardhat/contracts/.
You can interact with the BatchGraduationNFT in the /debug page.
5. Deploy and Interact
Update the BatchGraduationNFT.sol contract with the address of your Metadata Contract.
Once everything is set up, you can call the graduate function on the BatchRegistry contract.
6. View Your NFT:
Check if it appears on OpenSea or other platforms!
✅ Congrats you have now completed the Graduation NFT Challenge! Make sure to share it in the telegram! 🎉
Outline:
Alongside the BatchRegistry contract, a BatchGraduationNFT was deploy, you can see it in the hardhat/contracts folder
Check the graduate function on the BatchRegistry Contract. After doing some checks, it calls the mint function of the NFT contract
As you can see you'd need to deploy a Metadata Contract where you can set some attributes (color and name) for your personal NFT
You can interact with the BatchGraduationNFT in the /debug page (added in externalContracts.ts)
Once you set the address of the Metadata in the BatchGraduationNFT contract, you should be able to call graduate on the BatchRegistry contract.
Explain how they can see their minted NFT (getting the base64 contract, parse and render.... vs opensea?). We (as admins) could also provide some means to it (a hook / page)
Goal
Get your graduation NFT! 🎓
💡 This issue doesn't require you to raise a PR, just get yourself the completion NFT. Create a local branch to work on this.
WARNING: You are only able to mint one NFT on mainnet, so be careful when adjusting metadata and testing to only
graduateonce on mainnet.BatchGraduationNFT contract
The BatchGraduationNFT contract is deployed on Optimism.
