It argues that most LPs lose money from toxic flow and most users prioritize best trade prices, so prop AMMs can offer tighter spreads and lower fees. HiFi uses a single HiFiHook contract that fetches constant price updates via a simple quota interface, so routing to HiFi checks the latest pair price on chain and settles through the selected quota. The speaker reports that on Base with Coinbase BTC USDC, HiFi has the best price about 60 percent of the time for trade sizes, and around 50 percent for sells. They say they applied for an audit grant and are launching as is, citing product market fit.
