Ethereum is home to an array of token standards, each designed for specific use cases, playing crucial roles in its continuously expanding ecosystem. The constant pursuit of innovation drives the development of digital assets, creating new and creative token standards. Among the latest innovations is the experimental token standard known as ERC-404. This standard merges the features of ERC-20 and ERC-721 tokens to form a semi-fungible digital asset. This development marks a significant leap in token versatility, broadening the scope for asset ownership and exchange on the Ethereum blockchain.
What is ERC-404?
By incorporating the characteristics of both ERC-20 and ERC-721 token standards, ERC-404 enables developers to create fractionalized NFT collections. This approach facilitates a new type of digital asset that combines the benefits of fungibility and non-fungibility, broadening the possibilities for NFT utilization and ownership.
Each ERC-404 token corresponds to a particular NFT. When an individual achieves full ownership of a token, the corresponding NFT is minted and sent directly to the owner's wallet. If the owner decides to sell a portion of this token, the associated NFT is then burned.
Subsequently, if a wallet accumulates enough fractional parts of the token to constitute a full token, a new NFT is automatically minted to reflect this complete ownership. This mechanism allows for the fluid exchange of fractionalized NFT ownership while maintaining a direct link to the physical or digital asset.
Before the introduction of ERC-404, fractionalized NFTs existed, but were not as efficient as they could be. Typically, this process relied on an intermediary entity to lock the NFTs in a wallet and issue tokens representing ownership shares of that NFT. These fractionalized tokens could then be traded freely. However, ERC-404 enhances the user experience (UX) by making it more seamless. It streamlines the fractionalization process by natively integrating the fractionalization component directly into the asset. This approach allows ERC-404 to eliminate the need for seemingly redundant intermediary layers, thereby simplifying the process and reducing the steps required for users.
Potential Risks
Due to its recent introduction, ERC-404 is not yet an official token standard. Unlike established standards such as ERC-20 or ERC-721, ERC-404 has not been formalized through the traditional Ethereum Improvement Proposal (EIP) process, nor has it undergone a comprehensive external audit. The development team is in the process of drafting an EIP for the ERC-404 standard, although a timeframe has not been disclosed. Consequently, concerns have been raised by other developers regarding gaps and potential risks in the current iteration of its smart contracts. Some of these concerns have been acknowledged and are being addressed by the team.
Mantle's Role in the Evolving Landscape
Since the introduction of ERC-404 tokens, there has been a significant uptick in Ethereum's transaction volume, driven particularly by NFT and ERC-404 related transactions. This increase has significantly strained the network, leading to higher gas fees due to the additional computational resources required to process ERC-404 transactions. The escalation in gas fees emphasizes the need for the network to manage high volumes of transactions efficiently and in a cost-effective manner.
With its modular architecture, Mantle Network presents a promising solution to the high gas fees associated with the Ethereum network. Mantle Network ensures that transaction costs are significantly reduced by utilizing $MNT as the currency for gas fees. Consequently, the design of Mantle's architecture enables the platform to support the introduction of new and innovative token standards that may increase transaction volume, potentially resulting in higher-than-average gas fees.

Enter DN-404
The introduction of ERC-404 presented the ability to create fractionalized NFTs. Following this advancement, a new token standard, DN-404, emerged to build on the inherent drawbacks of ERC-404 tokens. Unlike ERC-404, which aimed to address these issues through a single contract, DN-404 uses a novel approach that separates ERC-721 and ERC-20 functionalities into distinct contracts — a "base" ERC-20 and a "mirror" ERC-721.
The primary functionality resides in the base contract, which operates as a fully compliant ERC-20 token. It tracks user balances and manages the minting/burning of mirrored NFTs. NFT minting occurs as an address accumulates a certain amount of base units, and if the balance drops below this threshold, their NFT is burned.
On the other hand, the mirror contract behaves like a standard ERC-721 token. The outcome is a seamless integration where both ERC-721 and ERC-20 contracts maintain their distinct functionalities as standalone entities yet operate on a unified infrastructure. This allows for efficient interoperability within the ecosystem. Protocols can precisely identify the type of asset being transferred because each contract address follows just one standard.
Final Thoughts
The introduction of ERC-404 represents a significant milestone in the evolution of NFTs, promising to redefine the principles of digital ownership. As this token standard undergoes a potential formal vetting process, it could herald a new era in digital asset management and trading. Furthermore, the introduction of ERC-404 has catalyzed innovation among developers, leading to the creation of alternative versions of the token standard, such as DN-404. This highlights how innovations like ERC-404 have inspired further innovation within the space.
