开源软件介绍：

Full stack NFT marketplace built with Polygon, Solidity, IPFS, Web3, Ether, Tailwind & Next.js

This is a full stack project with both frontend and backend connected.

Helping you to see how things are put together and not just writing solidity, or just interacting with a contract, etc but actually building the whole thing and testing it end to end.

Another interesting thing about this project is that we will be working with an Ethereum Scalability Solution like Polygon which helps us achieve things with cheap transaction fees.

We will be working with:

1. Hardhat: for the solidity development environmrnt
2. Ether: for client library to interact with chain
3. IPFS: for files uploads and files downloads
4. Web3 module: to enable us choose a wallet to work with...(Metamask etc)
5. Chai: for testing
6. OpenZeppelin/Contract: to inherit the ERC721 contract functionality.
7. NextJS: for our frontend app.
8. Tailwing: to simplify our styling.
9. Axios: for fetching data from library.

KEY NOTES:

1. look at the .gitignore file and find 3 key ignored files: provide yours to enable you run this app e.g

• a. .infuraId - get an ID from infura and place it here

• b. .secret - copy the private key of the wallet you intend to use and place it here

• c. config.js - when you run npx hardhat run scripts/deploy.js --network localhost/mumbai/mainnet the contract address will automatically appear there.

• d. NOTE: should the network fails when you using (`https://polygon-mumbai.infura.io/v3/${infuraId}`) at your index.js file, please copy and paste the full network including your ID and it will pass through.
