Prop AMMs can work for virtually any asset class. Today, Solana spot routers require DEXes to expose two interfaces: - getAmountOutGivenAmountIn [R] - swapAmountIn [W] A more opinionated router could instead require: - getBestPrice [R] - getAmountOutAtPrice [R] - swapAmountInAtPrice [W] In an integrated router-DEX landscape, on-chain routing looks almost identical to orderbook matching. With the right interfaces, the matching algorithms can also be asymptotically equivalent. There is no correct solution here: different matching algorithms influence trader behavior, and liquidity dynamics emerge from the resulting microstructure. The mechanics of matching are orthogonal to asset-specific derivative concerns (such as margin, settlement, and funding). As a result, a Prop AMM–based matching engine can serve as a general-purpose primitive, suitable for trading almost anything.

Why would going viral for something completely unrelated convert to sales for something completely different?
