When you buy an NFT, you're not just getting a picture—you're getting a verified piece of digital property, and that’s all thanks to NFT standards, technical rules that define how non-fungible tokens are created, tracked, and transferred on blockchains. Also known as token standards, these protocols are the backbone of true digital ownership. Without them, every NFT would be a lonely file with no way to prove it’s real, unique, or yours.
Two main standards dominate the space: ERC-721, the original NFT standard on Ethereum that gives each token a unique ID and full ownership control, and ERC-1155, a more flexible standard that lets one contract handle both unique and multiple identical tokens. ERC-721 is what powers most collectibles like CryptoPunks and Bored Apes. ERC-1155 is used in games and platforms where you might own 100 of the same item—like a rare sword or skin—and 1 of another, like a legendary armor set. The difference isn’t just technical—it changes how you use, trade, and even earn from NFTs.
These standards don’t exist in a vacuum. They connect directly to how NFT data is stored. Many early NFTs just linked to a JPEG on a server that could vanish tomorrow. But newer projects use Arweave, a permanent, decentralized storage network that keeps NFT files alive forever, or IPFS, a peer-to-peer system that avoids single points of failure. That’s why some NFTs hold value years later while others turn into broken links. It’s not about the art—it’s about the standards behind it.
And it’s not just about art or collectibles. NFT standards are now being used for fan tokens like VATRENI, access passes, event tickets, and even real-world asset representation. The same rules that let you prove you own a digital monkey also let you prove you own a seat at a concert or a share in a piece of real estate. That’s why regulators and big companies are watching closely. The future of digital ownership isn’t about hype—it’s about reliable, open protocols that anyone can build on.
What you’ll find below are real examples of how these standards play out in the wild—some working as intended, others collapsing under bad design. You’ll see how airdrops tied to NFTs succeeded or failed, how storage choices made or broke projects, and why some tokens vanished while others kept their value. This isn’t theory. It’s what happened when real people used these standards—and what you need to know before jumping in.
NFT standards like ERC-721 and ERC-1155 define how digital assets are created, transferred, and displayed on blockchains. They determine cost, compatibility, and usability-making them critical for collectors, creators, and developers.
