The batched auction is an off chain order book that is query a bi. There are solvers trying to find matchings, basically m right now it's not really centralized yet. They can get the order flow and they can even so in the protacle, they can also execute the settlement transactions. So they have access to to the entire order book. And are basically then trying craft solution to this multidimensional batch auction problem. It's multi dimensional, a auction with kind of lot of different liquidity sources where trades could come from.
Earlier this week, I did a deep dive on a new DEX trading protocol called CowSwap, which combines many good features into what is possibly the most complete trading experience in Defi.
First, you no longer publish a fee-paying transaction to the public mempool. Instead, you sign a transaction and submit it off-chain to the CowSwap relayer, which handles all the execution. For you, this means you can safely set a very low slippage tolerance because you only ever pay a fee if your trade succeeds.
Second, and this gets us to real innovation, CowSwap looks for so-called “coincidents of wants” or CoWs before sending your order to the regular on-chain exchanges. For example, if one trader wants to buy ETH at a certain price and another wants to sell it, these two can be matched without paying any LP fees. Off-chain solvers can look at this orderbook and submit optimal matchings that among others, guarantee that all trades in a certain batch have to settle at the same uniform price. Because there’s no point in reordering trades that have the same price, this also eliminates MEV as well.
Only after all coincidents have been exhausted, CowSwap sends the rest of the order to the on-chain exchanges via smart routers like 1Inch
If you didn’t get all of that immediately, don’t worry - neither did I, and that’s why I invited Felix Leupold from CowSwap and Gnosis to answer my remaining questions. Please enjoy my conversation on CowSwap with Felix Leupold.
