Magma is a liquid staking protocol built on Monad, allowing users to stake MONAD tokens and receive gMONAD in return, which can be used in DeFi. The platform distributes staking rewards along with extra APY generated from MEV (Maximal Extractable Value) rewards through blockspace auctions. Magma emphasizes community governance within the Monad ecosystem, allowing members to participate in decision-making and protocol direction.
