# Meta-Swap

Meta-Swap is an innovative mechanism of Fracton, referring to the One-Stop Swap for multiple token standards. Users can freely swap among ERC-20(hiNFT), ERC1155(People’s NFT), and ERC721(Original NFT) at a constant ratio in Meta-Swap. In addition, Meta-Swap can be seen as a reserve vault for every hiNFT collection. 

Users can Meta-Swap hiNFT to a randomized original NFT at the ratio of 1:1,000,000.
