How is metadata stored in pfp NFT?

Metadata in pfp NFTs (Profile Picture Non-Fungible Tokens) is typically stored on-chain using various methods. One common approach is to incorporate metadata as a JSON object within the token's smart contract. This allows for the inclusion of various details such as the image URL, its attributes, rarity, and even additional relevant information. The metadata can be stored in a Metadata URI field within the contract, often pointing to an IPFS (InterPlanetary File System) or HTTPS link containing the metadata JSON file. The metadata JSON structure usually follows specific standards like the ERC-721 or ERC-1155 metadata standards, ensuring interoperability and compatibility across different platforms and wallets. By storing metadata on-chain, pfp NFTs can retain their unique information and characteristics, enabling efficient management and recognition within the blockchain ecosystem.
