Polysynth Protocol is the first Polygon-based DEX that allows for the trading of perpetual futures contracts on assets such as cryptocurrencies, stocks, and commodities. Polysynth provides a scalable virtual market maker (VMM), which the company claims provides several advantages over traditional orderbooks or automated market makers (AMMs) because it's not using the collateralized debt position (CDP) model like AMM. Some advantages include access to liquidity, low slippage, and better quotes.
