Kine is a decentralized protocol which establishes general purpose liquidity pools backed by a customizable portfolio of digital assets. The liquidity pool allows traders to open and close derivatives positions according to trusted price feeds, avoiding the need of counterparties. Kine lifts the restriction on existing peer-to-pool (aka peer-to-contract) trading protocols, by expanding the collateral space to any Ethereum-based assets and allowing third-party liquidation.
