Uniswap flash loan

Flash swaps can be used to improve the efficiency of levering up using lending protocols and Uniswap. Consider Maker in its simplest form: a system which accepts ETH as collateral and allows DAI to be minted against it while ensuring that the value of the ETH never drops below 150% of the value of the DAI Flash swaps, as done on Uniswap, don't have flat fees (yet) but rather take a swap fee. This can be seen as a free loan compared to a flash loan because the swap fee is taken out of the trading order- we do not have to make a separate payment. Last point of difference: we can pay back flash swaps in either asset we're exchanging Flash loans can remove this obstacle to reduce the costs to loan interests, trading fees, and (blockchain) transaction fees. A wash trading endeavour to increase the 24-hour volume of the ETH/DAI market of Uniswap by 50% would for instance cost about 1,298 USD (with a flash loan from dYdX)
