Ethereum’s Big Move, ERC-6551: How This Upgrade Will Reshape the NFT Segment

Just a month ago, an eccentric Ethereum Improvement Proposal (EIP) surfaced, poised to revolutionize the technical design and economics of non-fungible tokens (NFTs). ERC-6551 has the potential to pave the way for new generations of NFTs while advancing the tooling of existing collections like Apes and Mutants.

What’s Inside the ERC-6551?

ERC-6551, introduced a mere five weeks ago as just a proposal, might open up a world of previously unseen opportunities in the NFT and digital identity realms. The Spartan Labs team acknowledges the significant implications this EIP carries.

Co-authored by the founders of CryptoKitties, the groundbreaking NFT collection, ERC-6551 enables non-fungible tokens to control ERC-4337-enabled cryptocurrency wallets. This means that NFTs can conduct transactions, store assets, and interact with decentralized finance (DeFi) protocols, essentially functioning as regular non-custodial wallets. The possibilities that arise from ERC-6551-powered NFTs are truly boundless.

Empowering Transparent Ownership and Interaction with DeFi

The ERC-6551 proposal introduces a paradigm shift by allowing NFTs to interact with DeFi protocols. With the ability to control wallets, NFTs can engage with decentralized financial applications. This functionality empowers NFT owners to utilize their tokens for various DeFi activities, such as lending, borrowing, and yield farming. Additionally, the integration of NFTs with wallets enables transparent ownership and the display of Proof of Attendance Protocol (POAP) tokens in a tamper-proof manner, enhancing the authenticity and value of the NFT ecosystem.

Creating Immersive Decentralized Gaming Experiences: One exciting application of ERC-6551-powered NFTs lies within decentralized gaming. By associating NFTs with in-game wallets, these tokens become integral components of the gaming experience. This integration enhances the immersion for players across different generations, providing unique benefits and interactions within the gaming environment. From collectibles to in-game assets, ERC-6551 paves the way for a new level of engagement and ownership in decentralized gaming ecosystems.

Current Status and Future Prospects: As of now, the ERC-6551 proposal, officially named “Non-fungible Token Bound Accounts,” is labeled with a “Draft” status on the Ethereum Foundation’s portal for EIPs. The proposal’s progress indicates ongoing discussions and evaluations by the Ethereum community to refine and solidify its technical and economic aspects.


ERC-6551, the visionary Ethereum Improvement Proposal, is set to emerg as a game-changer for NFTs, smart contracts, and wallets. With its ability to enable NFTs to control wallets and interact with DeFi protocols,
