ERC-404 The New Token Standard

ERC-404 The New Token Standard

The ERC-404 token standard represents an innovative experiment within the Ethereum network, aiming to combine the features of fungible tokens (like those of ERC-20) and non-fungible tokens (similar to ERC-721) into a singular, hybrid form. This allows assets to be both uniquely identifiable and divisible, offering a new way of representation on the blockchain. Let's explore the intricacies of ERC-404 tokens, their operational mechanics, their potential impact, and some notable ERC-404 initiatives worth noting.

Ethereum stands as the blockchain with the second-largest market cap, having significantly contributed to the evolution of blockchain technology and the wider cryptocurrency sphere. Its success is largely attributed to its adaptability, made possible through the use of smart contracts and programmable codes. These features facilitate the development of a variety of applications and decentralized finance (DeFi) products.

Token standards serve as the foundational guidelines for token creation, each designed with distinct features and intended uses. The ERC-404 token standard emerges as a cutting-edge development, exciting many with its innovative combination of fungibility and non-fungibility, paving the way for a new era of digital assets.

What Is the ERC-404

The significance of ERC-404 cannot be overstated. In essence, it transforms the concept of NFT ownership. Rather than owning an entire digital artwork, ERC-404 enables you to possess a portion of it, akin to holding a share in a valuable asset without the necessity of acquiring it outright. Furthermore, this standard facilitates multiple wallets holding interests in a singular NFT, expanding possibilities for using these fractions as loan collateral or asserting ownership in the digital domain.

The architects of ERC-404, known by the pseudonyms "ctrl" and "Acme", have crafted this token standard as a response to the community's needs. They've streamlined the process, eliminating the need for convoluted third-party protocols. However, it's important to note that ERC-404 is still in the proposal stage, akin to a novel dish that's being perfected before its official menu debut. The aim is to secure its place in the Ethereum ecosystem through a formal Ethereum Improvement Proposal (EIP).

Despite its unofficial status, the excitement around ERC-404 is palpable. Pandora, the inaugural token leveraging this new standard, has seen a meteoric rise in value, heralding the creation of a new sub-asset class within the cryptocurrency market. This buzz has spurred other projects to launch their ERC-404 tokens, contributing to a burgeoning ecosystem of innovation and speculation.

In essence, ERC-404 represents a groundbreaking fusion of fungible and non-fungible elements, heralding semi-fungible tokens that allow for fractional ownership of digital assets. This innovation not only enhances the liquidity of NFTs but also paves the way for fresh DeFi applications and strategies for digital asset management and trade. Through this, ERC-404 introduces a dynamic layer of versatility, liquidity, and programmable rarity to digital assets on Ethereum, embodying a new frontier in the NFT landscape and beyond.

How ERC-404 Tokens Work

Behind the scenes, ERC-404 tokens utilize smart contracts to orchestrate the distribution and proprietorship of underlying non-fungible tokens (NFTs). Each ERC-404 token signifies a distinct portion of an NFT, with the entirety of the supply reflecting the aggregate of these portions. Participants have the option to procure individual tokens or gather sufficient quantities to "burn" them, thereby acquiring the complete NFT in exchange. Here's an in-depth examination of the workings of ERC-404 tokens:

  • Fusion of ERC-20 and ERC-721: ERC-404 tokens are engineered to operate as both fungible (like ERC-20 tokens) and non-fungible (like ERC-721 tokens) assets. This dual functionality is achieved by associating each fungible token with a specific NFT, melding the traits of both types of tokens.
  • Fractionalized Ownership of NFTs: A pivotal attribute of ERC-404 tokens is their facilitation of fractional ownership over NFTs. By linking a fungible token to an NFT, it becomes possible to divide the NFT into smaller, exchangeable segments. This framework significantly boosts the NFT market's liquidity and makes it more accessible.
  • Flexible Minting and Burning Mechanisms: The trading of a fractional token that represents a segment of an NFT triggers the dynamic minting or burning of the associated NFT. Selling a part of a token leads to the burning of the linked NFT, whereas accumulating enough fractions to complete a whole token results in the automatic creation of a new NFT. This adaptable process ensures the fluid transfer and alteration of NFT ownership and attributes in alignment with the transactions of the underlying fungible tokens.

ERC-404 Tokens Use Cases

By introducing the concept of fractional ownership, ERC-404 tokens have the potential to greatly enhance the liquidity of NFTs. This innovation facilitates the trading of NFT portions without the necessity for a direct counterpart interested in acquiring the full asset, effectively overcoming a notable challenge in the conventional NFT marketplace. The innovative integration of fungible and non-fungible elements heralds exciting opportunities for NFT initiatives and uses, encompassing but not confined to:

  • Art & Collectibles: Fractional ownership opens the door to wider access to costly art pieces or scarce collectibles, making it more inclusive.
  • Real Estate: The tokenization of property assets through fractional ownership simplifies investment entry, making it more accessible.
  • Gaming & Metaverse: Assets within games or virtual lands can be segmented and exchanged with greater ease, enhancing the trading experience.
  • Decentralized Funding: It allows for the fractionalization of equity in startups or ventures, enabling community-based funding opportunities.

Top ERC-404 Projects

The ERC-404 token standard, which merges the features of both ERC-20 and ERC-721 tokens, has sparked the development of several noteworthy projects within the Ethereum network. Key players such as Pandora (PANDORA), DeFrogs (DEFROGS), and Monkees (MONKEES) stand out for their creative use of the ERC-404 standard.

Pandora (PANDORA)

Pandora, pioneering the use of the ERC-404 standard, demonstrates the potential of this innovation by linking each token to an NFT, thus enabling the fractional ownership and exchange of NFTs in a unique manner. This approach enhances the NFT market's liquidity and accessibility, allowing for the trading of NFT fragments as tokens, addressing some of the liquidity challenges traditionally associated with NFTs.

After its introduction, PANDORA quickly reached a peak value of over $32,000, showcasing the appeal of the ERC-404 trend. Although its price has decreased since that peak, it remains significantly above its initial trading price of $1,500.


Inspired by Pandora's success, DeFrogs capitalized on the ERC-404 standard with its series of 10,000 frog-themed Profile Picture NFTs (PFPs). Purchasing a DeFrogs token is equivalent to minting an NFT, with the project taking advantage of the standard's liquidity features to enable smooth token and NFT exchanges.

DEFROGS experienced a price surge to over $3,500, though not as dramatic as PANDORA's, and has since adjusted in value. Currently, DEFROGS trades at approximately $1,255.

Monkees (MONKEES)

Monkees, a recent addition to the ERC-404 ecosystem, offers a collection of monkey-themed PFPs and has experienced notable growth shortly after its launch. By leveraging the ERC-404 standard, Monkees facilitates the trading and ownership of NFTs, tapping into the growing interest in this new token type.

Other projects, such as Punks404 (PUNK) and EtherRock404 (ROCK), also make use of the ERC-404 standard, though they vary in their market presence and trading activity. These projects collectively underscore the versatility and potential of the ERC-404 standard in enriching the Ethereum ecosystem with innovative solutions for NFT trading and ownership.

The First ERC-404 Airdrops

The buzz around ERC-404 is unmistakable, with a flurry of projects quickly adopting this innovative trend by launching their ERC-404 token variants. Some projects have even enhanced their appeal by distributing a portion of their tokens to Pandora holders through airdrops, sparking additional interest in the token and generating excitement for these initiatives. Furthermore, a select few have expanded their horizons to other blockchains such as Arbitrum and Solana, striving to lead in new environments.

Heightening the excitement, prominent exchanges like OKX, Binance, and Bybit have endorsed ERC-404 tokens, announcing their integration into their Web3 wallets.
