Perpetual Protocol is a decentralized exchange (DEX) for trading futures on Ethereum and XDAI. Traders can conduct long or short transactions on more and more assets (such as BTC, ETH, DOT, SNX, YFI, etc.), with a leverage of up to 10 times. Trading is non -custody, which means that traders always retain their assets and in the chain. Perpetual Protocol uses a virtual automatic as a VAMM, which provides the liquidity on the chain and sets predictable pricing through the constant product curve. In addition, Perpetual Protocol designed its VAMMS to make its market neutrality and completely mortgage.
