Now it’s potential! That’s as a result of a brand new token normal, ERC-6551, simply arrived, and it propels Ethereum NFTs into a brand new realm of utility and performance.
Your favourite collectible can now instantly personal property, work together with web3 apps, and higher function your onchain identification. We’re entering into an thrilling period right here, so let’s get you up to the mark on the fundamentals of ERC-6551 for at present’s put up!

A Newbie’s Information to ERC-6551 📥
The fundamentals of ERC-6551
The relevance 🧠
ERC-6551, a brand new token normal, launched on the Ethereum mainnet on Might seventh, 2023. It considerably enhances the capabilities of ERC-721 NFTs by permitting them to function as their very own sensible contract accounts, making them extra versatile and practical than ever earlier than.
The why ❓
The motivation for ERC-6551 comes from the rising use of NFTs as a type of onchain identification. Till now, ERC-721 tokens could not act as brokers or personal different onchain property, which was out of sync with real-world use instances of non-fungible property.
Accordingly, ERC-6551 addresses this by granting every ERC-721 token the complete capabilities of an Ethereum account, whereas sustaining compatibility with present ERC-721 contracts. That is finished by deploying distinctive sensible contract accounts, termed “token sure accounts,” for every ERC-721 token through a permissionless registry.
Notice that it’s additionally potential for a single NFT to personal a number of token sure accounts through ERC-6551. On this sense, an NFT can now include a number of wallets and so forth.
The how 🔩
The system launched in ERC-6551 is primarily manufactured from 1) a permissionless registry for deploying token sure accounts, and a pair of) a regular interface for interacting with these accounts.
The what 🪪
Something you are able to do together with your common Ethereum pockets, now you can do with an ERC-721 NFT due to the ERC-6551 normal. In fact, the fundamentals could be utilizing your NFT to retailer different NFTs, commerce ERC20s, and many others. But that is simply scratching the floor!
For instance, let’s say you’ve been racking up NFT wearables in a brand new web3 sport. As an alternative of holding these in your common Ethereum pockets, now you can retailer them within the NFT of your alternative, e.g. your participant avatar from that very same sport. Not solely is that this funner and extra acquainted on a psychological stage, however later if you happen to’re prepared to maneuver on from the sport, you might think about promoting the participant avatar + accrued wearables as one cohesive unit on an NFT market through ERC-6551.
That’s only one hypothetical illustration, however there actually are tons of prospects right here. As one other instance, PFP tasks can now incentivize and enshrine deal with the expanded utility of their collectibles by airdropping rewards to any holders of their assortment with token sure accounts.
Additionally, the truth that ERC-6551 permits NFTs to have a number of token sure accounts and helps multi-chain token sure accounts gives extra layers of utility which are certain to kick off new waves of experimentation and innovation all through the NFT area.
The caveats 🤔
Not all NFT tasks are supported. Specifically, tasks whose sensible contracts don’t depend on an ownerOf methodology aren’t suitable with the ERC-6551 normal, e.g. CryptoPunks.
Past missing complete ERC-721 help as proposed, ERC-6551 additionally raises two essential security implications that may require some vigilance across the NFT ecosystem:
🚨 Avoiding Fraudulent Habits: Decentralized marketplaces have to be cautious of potential scams. For example, a situation the place a person sells an NFT that supposedly holds a specific amount of ETH, solely to withdraw the ETH after the sale, leaving the client with an empty account. Some steered methods to forestall such scams embrace monitoring token sure account nonces and guaranteeing asset commitments stay intact throughout a transaction. Nevertheless, stopping fraud just isn’t instantly addressed in ERC-6551 and requires implementation on the market stage or through exterior sensible contracts.
🔄 Stopping Possession Cycles: ERC-6551 may probably result in a scenario the place an NFT is transferred to its personal token sure account, inflicting all property in that account to change into completely inaccessible. This types an “possession cycle” which is complicated to forestall onchain as a result of infinite search area required. Whereas it is exterior the scope of ERC-6551 to implement prevention of those cycles, it is really useful for apps to take interface measures to restrict such transfers.
What individuals are saying 💬
• Benny Giang, ERC-6551 co-author and co-founder of Future Primitive: “The thought is straightforward … what if NFTs had their very own wallets? Impressed by Soul Sure Tokens (SBTs) our thought is the inverse and we name it Token Sure Accounts (TBAs) As an alternative of an NFT bounded to a pockets, we’ve got wallets bounded to NFTs.”
• Gami, Nouns DAO member and founding father of Gnars DAO and Tings DAO: “ERC6551 (Token Sure Accounts) is how I’ve thought of my Nouns ever since becoming a member of [Nouns DAO]. Hope to see us get behind it someway … Makes the ‘entreprenouner’ idea totally potential. Nouns could possibly be offered together with what they’ve acquired and constructed throughout their journey.”
• 0xBeans.eth, Solidity engineer: “ERC-6551 might be one of many extra fascinating utility stage Ethereum Enchancment Proposals … Numerous fascinating properties come up similar to tradable accounts … ENS is one step in the direction of onchain identities, full Ethereum accounts owned by NFTs is the subsequent step in my view. This EIP goes hand in hand with EIP4337 (account abstraction). The reference implementation basically create2s ETH accounts and bounds them to a token.”
The way to use ERC-6551 📂
Tokenbound is an open-source suite of instruments centered across the ERC-6551 normal, and one of many providers it supplies is an account explorer interface that you should use to deploy ERC-6551 accounts and work together with others.
In case you’re concerned about deploying a token sure account to your NFT of alternative, you’ll comply with these steps:
Go to https://tokenbound.org and join your pockets of alternative
Click on the “My NFTs” button
Choose your required NFT and press the “Deploy Account” button
Affirm the deployment transaction together with your pockets, and watch for the transaction to finish
That’s it! You’ll now see a “Use Pockets” possibility within the dashboard of your chosen NFT; on the time of writing I obtained a “Coming quickly…” message, so search for full performance to be rolled out briefly order
Certainly, take into account that ERC-6551 simply arrived on mainnet, so the tooling round it’s simply starting to be developed. Count on to see all types of “person expertise” and “person interface” developments right here going ahead. Within the meantime, I like to recommend taking a while to evaluation the FAQ on the backside of tokenbound.org earlier than diving in.

The large image 🤯
The arrival of ERC-6551 is a historic milestone within the NFT area and opens up a world of recent prospects by turning NFTs into their very own sensible contract accounts. This brings significantly extra versatility to NFTs, however it additionally aligns them extra carefully with real-world use instances, making them extra sensible and relatable for customers. Zooming out, look ahead to elevated ERC-6551 adoption and experiments within the months forward!
Moreover, now anytime skeptics say NFTs can simply be “right-click saved,” we now have token sure accounts inside NFTs that make this cost that rather more baseless. You’ll be able to copy and save an image, certain, however you possibly can’t copy and save the contents inside 😉
