Developers Unveil Alternative ERC-404 called DN-404

On February 12th, crypto developers released an alternative implementation to the experimental ERC-404 token standard DN-404. This rival version seeks to achieve the same capabilities as ERC-404 in a more efficient manner.

The premise of ERC-404 was creating a single contract that can act as both a fungible and non-fungible token. However, the developers behind DN-404 argue this introduces inefficiencies and breaks standards. 

Instead, DN-404 uses two separate contracts – an ERC-20 token and paired ERC-721 NFT. By splitting the functionalities, the developers claim potential issues can be reduced while retaining the core benefit of native NFT fractionalization.

We haven’t benchmarked it vs cellmates, so I can’t speak to that side of things. I can say that it averages about 20% gas savings vs erc404. DN404 is built for full backwards compatibility with everything that’s been built for 721s, 20s, or both.

“The result is that everything returns to the way it should be. The ERC-721 and ERC-20 contracts both exist, and both function as standalone products, but under the hood, they run on shared 404 rails,” explained one of the pseudonymous developers.

The developers estimate that the modular approach of DN-404 could enable a 20% reduction in transaction fees associated with ERC-404. However, they caution that risks remain as the code is currently unaudited.

Unlike the ERC-404 launch, an actual implementation of the token-NFT hybrid has not yet occurred using DN-404. But given interest around 404, the developers decided to open-source their take for the community’s benefit.

ERC-404 was introduced on February 2nd by the Pandora team to much fanfare. By allowing NFT fractions to be freely split and merged, novel applications like NFT indexes, tokens with changing supplies, and dynamic NFTs become possible.

However, controversy emerged around significantly increased gas fees on Ethereum after the ERC-404 token launch, sparking backlash and leading to projects like DN-404. The rival promises similar capabilities but with optimized efficiency.
