Eris Protocol is a DeFi platform focused on liquid staking and yield optimization, primarily in the Crypto Defi Cosmos ecosystem, which serves as a core "engine" for liquidity alliances, notably the Terra Liquidity Alliance (TLA). It enables users to stake assets, receive liquid derivative tokens (like ampLUNA or arbLUNA), and use them to earn multiple, simultaneous yield streams—such as staking rewards and LP fees—to bootstrap deep liquidity for partner protocols.
