NFT Contract with Minting and Metadata

• Simple NFT contract.
• Supports minting multiple tokens and addition of metadata for images.
• Bunch of tests to ensure the contract works as expected.
• Based on the ERC721 standard.
• Extends OpenZeppelin ERC721 contract.
• Uses Hardhat for testing and deployment.
• Works on any EVM chain, just setup Hardhat config appropriately.

Making Changes

• Make changes to the contract in contracts/Dogs.sol.
• Parameters are defined in the constructor.

yarn install

Notes

• Don't forget to add your keys to .env
• Don't prefix private key with 0x
• You'll need to host NFT metadata somewhere. Simple web server will do. Or IPFS.
• You can use the mint function to mint tokens.
• Payments accrue in the contract.
• Withdraw payments using the withdraw function.
• Only the deployer of the contract can withdraw payments.

Enjoy!
