### tl; dr
* 0x request-for-quote (rfq), mev proof + zero slippage trades
* all communication happens off-chain until settlement, making the system extremely gas efficient for market makers
* trades are impossible to front-run or sandwich: no mev
* trades have zero slippage, zero fees (aside from gas), and are settled at a predetermined price
* highly capital efficient (max trade size = balance of market marker)
* rfq liquidity is composable
* off-chain orders, on-chain settlement
* the `txOrigin` field must be set and enforces that the order can only be filled by the specified address - it is impossible for any other trader or bot to front-run the trade.
