Originally launched as Melon Protocol in 2017 and rebranded in 2021, Enzyme is a decentralized asset management protocol built on Ethereum and also deployed on Polygon. It enables individuals and communities to create, manage, and invest in customizable on-chain investment vaults. The protocol is non-custodial, meaning users always retain control of their assets. Enzyme provides a transparent and automated framework for portfolio management, including features for trading, yield farming, and lending, with enforceable on-chain rules for fees and risk management. The core development and maintenance of the protocol are led by Avantgarde Finance AG.
