The world #kripto is currently being shocked by the emergence of a new trend, namely ERC-404 standardized tokens. Even though it is still in the experimental stage and has not been fully audited by external parties, this token has managed to attract the attention of investors.### Getting to know ERC-404ERC-404 is an unofficial #Ethereum token standard that gained popularity thanks to the Pandora project. Currently, Pandora's capitalization stands at US$234 million, with token #PANDORA having a value of US$29,000, an increase of 10,000% since its launch on February 2. ERC-404 combines the advantages of ERC-20 (ordinary tokens) and ERC-721 (NFT), where each purchasing one token will get one NFT. It is important to note that ERC-404 transactions are valid in integer multiples, for example, one token gets one NFT, two tokens get two NFTs, and so on. ### Risks of ERC-404 Tokens Despite offering innovation, ERC-404 also has some risks things to consider: 1. Unrecognized Status: ERC-404, although following the ERC standard format, is not yet recognized as an official Ethereum standard, it is only experimental.2. Can't Choose NFT: Users purchasing ERC-404 tokens on Uniswap cannot choose which NFT to acquire, presenting a practical challenge.3. Potential for Manipulation: There is a risk of manipulation of NFT scarcity, with predictable algorithms, unfairly influencing the market and distribution.4. Experimental Stage: ERC-404 is still in the experimental stage, so investors are cautioned against being too tempted by hype and FOMO, while evaluating long-term practicality and stability. While ERC-404 promises greater NFT flexibility, it is important for market participants to consider the risks -these risks before fully adopting this mechanism.
