What is the best "order book type" (i.e. not using bonding curve ala Uniswap) DEX out there? I got asked the question and I am surprised I could not come up with a name 👀 I initially would have said 0x but I think they pivoted away from that vision...
Dydx I think Solana has some CLOBs Ethereum block timess are too long and it's too expensive to keep updating chain state with the latest order book prices
Onchain order books are hard to do efficiently, though there’s some progress here: https://www.youtube.com/watch?v=xUosFwSdVU0&t=51m14s Hybrids like CowSwap (and I think UniswapX) do off-chain decentralized order matching, but fall back to AMMs.
