Universal Market Access (UMA) has launched their Synthetic Token Builder on Rinkeby testnet that allows the creation of tokens to track the price of anything from the S&P500 to number of Twitter followers an account has. The dApp works by creating a token that is overcollateralized with $DAI. The collateralization ratio will fluctuate based on the price of the underlying instrument, and if it drops below the requirement it will be liquidated for a penatly.
