Our company is going to implement a simple NFT mint. The artwork is ready. The website is available, with only basic web3 integration. Your job is to create / provide a smart contract and plug it to the front-end. It is on an ethereum layer 2, so the contract will be in solidity. There is no element of randomness, it's a single picture. There is a finite amount of mint, after which no NFT can be minted again. Also needs to be transferable.
