I am pleased to offer a service that includes the delivery of a Smart Contract written in Solidity that is based on ERC721 Token (NFT). This contract will be connected to a Single Page Application that has been built on React.js. I will utilize the Graph Protocol or another protocol of your preference to index the events. In this service, I will focus on implementing the primary functions of the contract, such as minting and transfer.

To give you a better idea of what to expect, I have attached a screenshot of a sample dapp that has similar features to what will be included in this service. 

However, if you require any special customization, please do not hesitate to reach out to me for further discussion. 

All source codes will be provided as well
