 Now that stablecoins and synthetic assets have been defined and classified, you might be wondering what makes XST stand out from the rest?
 
-XST helps to solve the problem of XOR liquidity by creating synthetic assets backed by a variable amount of XST and pegged to a target index (e.g., a currency). XST is minted/deminted to always guarantee the value of the pegged index. The first index implemented is linked to the value of DAI and will be called XSTUSD.

 Normally, algorithmic stablecoins derive their value from smart contracts linked to oracles that determine current prices, however, XSTUSD's value is currently derived from the price of XOR-DAI.
