When you hear about NFTs, you might think of digital art or profile pictures. But behind every NFT is a standard—a shared rule set that makes it work across platforms, wallets, and marketplaces. These standards are the foundation that allows NFTs to be created, traded, and owned in a secure and compatible way. If you’re interested in building, collecting, or trading NFTs, it helps to understand what these standards are and why they matter.
You don’t need to be a developer to appreciate how standards shape your experience in the NFT space. Knowing what’s under the hood gives you more confidence when choosing projects, evaluating assets, or building your own ideas.

What Are NFT Token Standards?
An NFT token standard is like a blueprint. It tells blockchain networks how NFTs should behave, how they can be transferred, and what data they carry. These rules ensure that NFTs are more than just random files on a blockchain—they are consistent, traceable, and usable across many systems.
Without a shared standard, every project would have to build its own rules from scratch. That would make it hard for wallets and marketplaces to understand and interact with each asset. Standards simplify the process, allowing for broader adoption and better support.
Think of it like this: If every outlet had a different shape, you’d need a different plug for every device. Token standards are what make it possible to have one kind of plug that fits into many systems.
ERC-721: The First NFT Standard
ERC-721 is the original token standard that brought NFTs into the spotlight. Introduced in 2018 on the Ethereum blockchain, it defines how each token is completely unique. Every ERC-721 token has its own ID and metadata, making it ideal for art, collectibles, and gaming assets.
Most popular NFT projects, including CryptoPunks and Bored Ape Yacht Club, use ERC-721. It’s widely supported and easy to integrate with platforms like OpenSea. But because it treats each token as a separate contract entry, it’s not always efficient when you’re dealing with lots of items at once.
Still, if you want to create a 1-of-1 artwork or a limited-edition collection, ERC-721 is one of the most trusted formats out there.
ERC-1155: A More Flexible Option
ERC-1155 was created to handle more complex use cases, especially in gaming. It allows you to create both fungible and non-fungible tokens in one smart contract. That means a single collection can include unique NFTs and interchangeable items, like in-game currency or shared gear.
For example, a game might use ERC-1155 to mint one-of-a-kind weapons as NFTs and also offer standard tokens for power-ups. This flexibility makes it cheaper and faster to mint and transfer items.
Because ERC-1155 reduces the amount of data stored on-chain, it’s often more efficient than ERC-721 for large-scale projects. It’s also easier to batch transactions, which saves gas fees.
ERC-998 and Composability
ERC-998 is a lesser-known standard that adds a layer of composability to NFTs. It allows NFTs to own other tokens—both fungible and non-fungible. That opens up new ways of bundling assets.
Imagine owning a digital house (an NFT) that includes furniture (other NFTs) and even some tokens for in-game currency. ERC-998 lets all of those assets travel together as one unit.
This kind of nested ownership hasn’t seen as much mainstream adoption yet, but it offers interesting possibilities for virtual worlds, metaverse assets, and advanced collectibles.
Solana, Flow, and Other Blockchains
While Ethereum-based standards like ERC-721 and ERC-1155 are the most widely used, other blockchains have their own token formats. Solana, for instance, uses Metaplex standards. Flow, the blockchain behind NBA Top Shot, has its own way of handling NFTs through Cadence, its native smart contract language.
These alternative blockchains are often faster and cheaper to use, which is why they attract gaming projects and large-scale collectibles. However, they may not be as broadly supported as Ethereum standards, so cross-chain compatibility can sometimes be an issue.
Still, many developers are building bridges and tools to make NFTs more portable across different ecosystems.
Why Standards Matter to Everyone
For creators, standards make it easier to launch projects without reinventing the wheel. Artists and developers can focus on design and experience instead of coding complex backend rules. Standards also open the door to automatic listing on marketplaces, built-in wallet support, and access to analytics tools.
For collectors, standards offer consistency. Whether you’re buying a token on OpenSea, storing it in MetaMask, or viewing it in a gallery app, you know what to expect. You also get transparency—each token ID, contract, and transfer can be verified.
For developers, standards reduce time-to-market and bugs. They also offer security benefits, since widely used standards are battle-tested and reviewed by the community.
The Future of NFT Token Standards
As the NFT space matures, new standards will likely appear to address emerging needs. For example, creators want better royalty enforcement, and collectors want more secure storage. Projects are already exploring ideas like on-chain metadata, time-based ownership, and dynamic NFTs that change based on external data.
Standards are evolving to keep up with new use cases—whether it’s identity verification, gaming economies, or ticketing systems. Some developers are pushing for modular smart contracts that allow easier upgrades without breaking compatibility.
There’s also growing interest in cross-chain standards that let NFTs move between networks without losing their history or features. These efforts could make NFTs more flexible and reduce fragmentation across ecosystems.
Staying Informed and Involved
If you’re working with NFTs, it’s good to stay informed about changes in standards. You can follow updates on GitHub, track what developers are proposing in forums, or join discussions in Discord and Telegram groups.
You don’t have to be a coder to care about token standards. Even if you’re just collecting or supporting projects, knowing the basics helps you make smarter decisions.
Understanding standards means you’ll know what kind of rights you hold, what tools are available to you, and how secure or future-proof your NFT might be. In a space where innovation moves fast, a little knowledge can go a long way.
NFT token standards are the glue that holds the ecosystem together. From ERC-721 to new blockchain-specific formats, these rules ensure that NFTs are readable, reliable, and interoperable. Whether you’re minting your first piece or building a full project, understanding these standards helps you connect with a wider audience and operate with confidence.
