Introducing ERC404 – The Merging of ERC20 and ERC721

ERC404, the newest token standard on the block, combines features of both ERC20 and ERC721 standards. This experimental standard has been gaining traction in the crypto community, with an astounding $87 million in trading volume on decentralized exchanges within its first week. Additionally, nearly $1 million worth of ERC404 tokens have been traded on NFT marketplaces. So what exactly is ERC404 and why is it generating so much interest?

The Birth of Pandora 

Pandora, the first project built on the ERC404 standard, offers a unique combination of 10,000 ERC-20 tokens and 10,000 associated “Replicant” NFTs. 

What sets this project apart is the dynamic relationship between the tokens and NFTs. For every full PANDORA token purchased on an exchange, 1 Replicant NFT is minted to the buyer’s wallet. On the other hand, selling 1 PANDORA token results in the connected NFT being burned. 

This creates a constantly fluctuating market for these unique Replicants. And as expected, the demand for these tokens and NFTs has been skyrocketing since its launch.

Merging the Best of ERC20 and ERC721

ERC404 may still be in its early stages, but it is already showing immense potential. By merging the rules of ERC20 and ERC721, this standard allows each Replicant to have properties of both a token and an NFT. This is a significant deviation from fractionalized NFTs, which only allow for partial ownership of an NFT. 

Furthermore, ERC404 improves liquidity for NFTs by enabling users to sell tokens on popular decentralized exchanges like Uniswap, which has substantial liquidity. And when a fungible token linked to an NFT is sold, the NFT gets destroyed, creating a dynamic market for rare Replicants.

The Future of ERC404 

It’s no surprise that ERC404 has already generated high trading volumes and substantial fees for liquidity providers on Uniswap. Marketplaces like Blur have quickly integrated this standard, with other platforms and NFT projects following suit. The potential for ERC404 is endless, and it’s only a matter of time before more projects adopt this standard.


In conclusion, ERC404 is an innovative step towards merging the features of ERC20 and ERC721 standards. With its first project, Pandora, already making waves in the crypto community, it’s no doubt that this new token standard has tremendous potential. 

As more platforms and projects integrate ERC404, we can expect even higher trading volumes and a dynamic market for rare NFTs. Keep an eye out for this new standard as it continues to shape the world of crypto and NFTs.
