MKR is the native governance token of the Maker Protocol, a decentralized finance (DeFi) platform built on the Ethereum blockchain. It allows users to create and manage the stablecoin DAI, which is pegged to the U.S. dollar. Holders of MKR can participate in the decision-making process of the protocol, influencing changes to the system and its parameters. MKR tokens are used to maintain the stability of DAI and ensure the overall health of the Maker ecosystem. When the value of DAI deviates from its peg, MKR can be minted or burned to help restore balance. This mechanism helps to keep the system decentralized and resilient.
