#ERC404 , an experimental and unofficial Ethereum token standard, combines the functionalities of #ERC20  (fungible tokens) and ERC-721 (non-fungible tokens or #NFTs ) into a single standard12. Unlike traditional NFTs, which exist as one-for-one assets, ERC-404 allows multiple wallets to directly own a single NFT. In the future, this specific exposure can be tokenized and used for purposes such as taking out loans or staking holdings1. The recent launch of #Pandora , the first token based on ERC-404, has sparked significant interest in this novel approach. Pandora’s value skyrocketed from $250 to as high as $32,000 within a week, with a trading volume of $76 million in the past 24 hours1. Other projects have also embraced ERC-404, issuing their own versions of these tokens and creating a new sub-asset class in the crypto market. Major exchanges like OKX and #Binance have announced support for ERC-404 tokens on their Web3 wallets, further legitimizing this experimental standard1
