Description:   #NFTs with On-Chain Metadata - Hardhat and JavaScript  Not storing your metadata on the blockchain will make interacting with it from your smart contract impossible, as the blockchain can't communicate with "the external world".  L2 chains such as Polygon are here to help, drastically reducing Gas costs, and introducing a number of advantages that allow developers to expand the functionalities of their applications.  When creating NFTs, is good practice to store the metadata on centralized object storages or decentralized solutions like IPFS, to avoid the humongous Gas fees derived from storing big amounts of data, such as images and JSON Objects, directly on-chain.
