What is ERC-404? Exploring the Revolutionary ERC-404 Token Standard

In a groundbreaking development, the cryptocurrency world is buzzing with the advent of the ERC-404 token standard. This innovative standard seamlessly merges the functionalities of fungible (ERC-20) and non-fungible (ERC-721) tokens, presenting a promising solution to the liquidity challenges faced by NFTs. The term “ERC-404” is making waves, capturing the attention of enthusiasts and experts alike.

How Does ERC-404 Work?

Picture this: ERC-404 operates by intricately linking each fungible token to a corresponding NFT. Let’s break it down – a project can introduce 100 tokens and 100 NFTs, establishing a one-to-one relationship. When a user purchases a fraction of a token, the related NFT undergoes the burning process, and voila, they possess a fraction of the token. And here’s the kicker – combining token fractions results in the minting of a brand new NFT right into the buyer’s wallet.

Pros and Cons of ERC-404

Now, let’s weigh the pros and cons of this intriguing token standard:


Liquidity: ERC-404 sets out to tackle the age-old liquidity dilemma faced by NFTs, introducing a streamlined buying and selling process.

Fractionalization: Embracing ERC-404 brings forth native fractionalization of NFTs, promising users a superior and more engaging experience.


Unaudited: It’s worth noting that ERC-404 is currently unaudited. This implies potential vulnerabilities that could pose risks to users, emphasizing the importance of cautious exploration.

Projects and Adoption

The pioneer in adopting the ERC-404 standard goes by the name Pandora. This trailblazing project has unleashed 10,000 NFTs known as Replicants, intricately tied to an equivalent number of Pandora tokens. These NFTs, boasting varying levels of rarity, can be minted or burned based on token transactions, introducing a new dimension to the world of digital assets.

Excitingly, numerous projects are dipping their toes into the ERC-404 waters. Peopods Finance, for instance, has seamlessly integrated the Pandora token for yield generation. Teller is leveraging it as collateral for loans, while Wasabi Protocol has boldly listed it for perpetual trading.


In conclusion, the ERC-404 token standard emerges as a beacon of innovation, bridging the gap between fungible and non-fungible tokens while aiming to revolutionize NFT liquidity. As the crypto community eagerly watches, it’s evident that ERC-404 is poised to reshape the landscape of digital assets.
