0x protocol

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.
