npx hardhat run scripts/deploy.js --network mumbai

• Replace the provider in the index.js file inside the loadNFTS() function with the following

/* pages/index.js */

/* old provider */
const provider = new ethers.providers.JsonRpcProvider()

/* new provider */
const provider = new ethers.providers.JsonRpcProvider("https://rpc-mumbai.maticvigil.com")

Demo

• Deployed contract on Polygon Mumbai Testnet using Infura RPC endpoint: https://mumbai.polygonscan.com/address/0x31fa64d843a4e384ce3e6a68d078c67bef884221

• Contract Address: 0x31fa64d843a4e384ce3e6a68d078c67bef884221

You can use the above address instead of deploying your own contract to test the app, but you will have to replace the contract address in the config.js file with the above address, compile the NFTMarket.sol contract for it's abi and still replace the provider as shown above.
