Last week ERC404 attracted a lot of attention, once led to a spike in ethereum gas, at present $PANDORA after a retracement in the $20,000 or so shock, @Pandora_ERC404 proposed ERC404 is a hybrid FT/NFT protocol for NFT fragmentation, today to briefly chat about the development of the NFT splitting track it.With the arrival of NFT summer in 2021, the price of blue-chip NFTs such as CryptoPunk and Boring Ape has risen to the point where ordinary users can’t afford to pay, and the liquidity problem has always been one of the major pain points of NFTs, so the demand for NFT splitting peaked at that time, and this demand has actually been perceived by many project parties at a very early stage.One of the early solutions is NFT crowdfunding, which is generally a centralized way of crowdfunding to buy NFTs, but there are many problems with crowdfunding: for example, the custody of NFTs, not convenient enough for withdrawal or transfer, etc. So the project of fragmentation of NFTs in a decentralized way came into being.
