Perpetual Protocol is a decentralized exchange (DEX) for futures on Ethereum and xDai. Traders can go long or short with up to 10X leverage on a growing number of assets like BTC, ETH, DOT, SNX, YFI and others. Trading is non-custodial, meaning traders always retain possession of their assets, and on-chain. Perpetual Protocol utilizes a virtual automated market maker (vAMM), which provides on-chain liquidity with predictable pricing set by constant product curves. Furthermore, Perpetual Protocol designed its vAMMs to be market-neutral and fully collateralized.
