Maker is a peer-to-contract lending platform enabling over-collateralized loans by locking Ether in a smart contract and minting Dai, a stablecoin pegged to the US dollar. Dai's stability is achieved through a dynamic system of collateralized debt positions, autonomous feedback mechanisms and incentives for external actors. Once generated, Dai can be freely sent to others, used as payments for goods and services, or held as long term savings.
