Tranquil Finance is an algorithmic money market and liquid staking protocol on the Harmony ONE blockchain. The money market allows users to supply and borrow assets while receiving or paying interest in a completely permissionless and decentralized way. Borrowing and lending interest are set based on market demand, and loans are over-collateralized to ensure solvency.

Another feature in Tranquil Finance is the liquid staking token, stONE, which allows the user to stake ONE for rewards while also being able to use it in Harmony's DeFi ecosystem, such as using it as collateral on Tranquil Lending.
