NFT20 is a decentralized exchange and protocol for tokenizing NFT projects as ERC20 tokens to make them tradable on decentralized exchanges such as UniSwap or Sushiswap. Anyone can add their NFT to the appropriate pool and receive ERC20 token derivatives representing that NFT project that can be traded on dexes right away. By creating a secondary market of ERC20 derivatives of NFTs, NFT20 hopes to address the liquidity problem in the NFT space. Addressing this problem allows for arbitrage opportunities, allows investors to gain price exposure to NFT projects without identifying and buying individual NFTs, and allows for fairer price setting and easier trading of NFTs by collectors and newcomers alike.
