ERC404: An Analysis of the Experimental Asset Standard Merging FT and NFT
In-depth Analysis of ERC404: A New Asset Class with Both Potential and Risks
Introduction
Every round of the cryptocurrency bull market brings new asset issuance methods and technical standards. From Ethereum's ERC20 to ERC721, and now to the recent BTC chain inscriptions, the market continuously sees innovation. This article will introduce the experimental standard ERC404 on the Ethereum chain and its first asset, Pandora.
ERC404 implements a corresponding interchangeable relationship between FT and NFT, while utilizing the bilateral liquidity of ERC20 and ERC721. Each FT will automatically mint an NFT; if there is less than one, it will not be minted. Buying, selling, or transferring integer FT will trigger the destruction and re-minting of NFTs, randomly generating new NFT attributes. Users can also directly trade NFTs to retain specific NFTs.
It should be noted that ERC404 is currently still an experimental standard and has not yet been formally incorporated into the Ethereum standards. As the first ERC404 asset, Pandora carries a higher risk, and investment should be approached with caution.
Pandora Case Study
Project Introduction
Pandora was launched on February 2nd, issuing 10,000 PANDORA ERC20 tokens, corresponding to 10,000 "Replicants" NFTs. Pandora can be traded on platforms such as Uniswap and OpenSea.
NFTs are divided into 5 rarity levels, distinguished by colors. When trading FT, the NFT will increase or decrease accordingly. Each time an NFT is regenerated, the rarity is randomized. Directly trading NFTs will not change their rarity.
market data
As of March 2:
On Uniswap V3:
Comparison of FT and NFT
The total trading volume on DEX is $870 million, while the NFT trading volume is only $6.6 million ### 10.7% (. The core liquidity of Pandora primarily comes from Uniswap V3 AMM pricing.

) Coin Distribution
Among the top 10 addresses holding tokens, the top 3 are the official multi-signature wallet, Uniswap V3 LP, and Sablier V2 LockupLinea contract. The chips are relatively dispersed, mainly distributed in the range of 19000-27000.

ERC404 Technical Principles
) lossy encoding scheme
ERC404 utilizes a lossy encoding scheme to use the same data structure "AmountOrId" for the quantity of ERC20 tokens and the IDs of ERC721 tokens in contract storage.

) main defect
When burning multiple NFTs, it is not possible to control which specific NFT is destroyed; the last acquired NFT will be destroyed according to the LIFO mechanism.
Due to the need to monitor multiple balances and NFT ownership, gas consumption is relatively high.

) Pseudorandom Number Design
Pandora uses NFT IDs as a source of pseudo-random numbers, granting different attributes and rarity. In fact, it is "drawing cards" in a preset order.

Comparison with NFTFi
ERC404 cleverly utilizes existing facilities of NFTs and FTs to establish bilateral liquidity, featuring new characteristics such as "card drawability", "native fragmentation", and "AMM liquidity", which significantly differ from mainstream NFTFi business models.

Summary and Outlook
ERC404, as a new asset class, cleverly combines the advantages of NFTs and FTs, establishing bilateral liquidity. In the future, it may be applied in scenarios such as full-chain GameFi and functional NFTs, but market validation is still needed.
