Pandora’s Experimental ERC-404 Standard Grabs Attention

The Pandora project went live on February 2. It launched a new, experimental token standard named ERC-404.

The new standard combines the popular ERC-20 (token standard) and ERC-720 (NFT standard). It is open-sourced for creators and developers.

Per GitHub, ERC-404 is an experimental, mixed ERC20 / ERC721 implementation with native liquidity and fractionalization. “While these two standards are not designed to be mixed, this implementation strives to do so in as robust a manner as possible while minimizing tradeoffs,” the team said.

As a collection, Pandora comprises 10,000 so-called Replicants enabled by ERC-404. Replicants are generative avatars. Each is attached to a PANDORA token.


When a Pandora ERC404 is sold or transferred, it’s corresponding replicant is destroyed and a new one is generated in it’s place.

There are 5,318 Replicants on the OpenSea marketplace. The lowest price is currently 11 ETH, and the highest is 100 ETH.

As for the token, the team said that PANDORA is the first token built on the ERC-404 standard. The price of PANDORA is currently $24,626, up 135.% over the past 24 hours.


Pandora stresses that the standard is “entirely experimental and unaudited,” though they completed some testing. It later stated that an independent audit is underway.

All that said, many people still have questions about the project’s specifics, while some question the very existence of ERC-404.

Meanwhile, other collections have also started experimenting with the new standard.

Excited to see more established ERC721 collections build with ERC404. 2% of the collection will be airdropped to our holders

— Pandora (@Pandora_ERC404) February 7, 2024

The first of many @rugged_dot_art is an experiment deployed by the team at @floorprotocol, a protocol that was early to exploring NFT liquidity solutions for ERC721s.

We’re extremely excited that they’re excited about ERC404. Bullish on real, experienced teams.

— Pandora (@Pandora_ERC404) February 7, 2024

The team also announced a partnership with Vector Reserve.

Our inbox is on fire but we’re doing our best to get back to all of the projects that are building with ERC404 without losing focus on delivering value to our holders.

If your project is planning an airdrop or any incentives for Pandora holders please make sure to let us know!
