Follow tokenURI from a contract to the name, attributes, image, animation, and nested dependencies a marketplace renders.
Learn how NFT metadata and storage work
Practical guides to NFT metadata, IPFS and Arweave storage, fully on-chain NFTs, and the contract controls that can change a collection.
NFT storage
Compare on-chain data, IPFS, Arweave, gateway URLs, and ordinary web hosting by integrity, mutability, and availability.
On-chain NFTs
Separate on-chain ownership from on-chain metadata and media, and identify the dependencies that still remain.
NFT contract control
Understand owners, roles, multisigs, timelocks, proxies, and the practical power each controller may retain.
