Compound

Compound is an open-source protocol for algorithmic Money Markets on the Ethereum blockchain.

Compound is a protocol on the Ethereum blockchain that establishes money markets, which are pools of tokens with algorithmically derived interest rates, based on the supply and demand for the token. Suppliers (and borrowers) of an asset interact directly with the protocol, earning (and paying) a floating interest rate, without having to negotiate terms such as maturity, interest rate, or collateral with a peer or counterparty.

Individuals with long-term investments in Ether and tokens (“HODLers”) can use a Compound money market as a source of additional returns on their investment. For example, a user that owns OmiseGo can supply their tokens to the Compound protocol, and earn interest (denominated in OmiseGo).

Compound allows users to frictionlessly borrow from the protocol, using collateralized lines of credit, for use anywhere in the Ethereum ecosystem. Unlike peer-to-peer protocols, borrowing from Compound simply requires a user to specify a desired asset; there are no terms to negotiate, maturity dates, or funding periods; borrowing is instant and predictable.
