Introducing stONE — the first liquid staking token for Harmony ONE


At launch, we will delegate ONEs staked with stONE to a handpicked list of 20 validators, but in the long run, we want to use stONE to help improve the decentralization of the Harmony blockchain by onboarding a diverse set of validators.

Our long term vision for stONE is for it to replace ONE as the currency of choice within Harmony. We aim to increase the utility of stONE across the entire ecosystem so that holders can receive staking rewards while also taking advantage of the yields and growing capabilities of DeFi applications on Harmony.

Use Cases

Moreover, Harmony has a lengthy undelegation time of several days, which further increases the friction of staking ONE versus using it with DeFi applications.

Our liquid staking token, stONE, solves these problems by letting the user stake their ONE for rewards, while at the same time receiving a token (stONE) that can be used with in DeFi to earn even more yield.

Furthermore, the stONE backend autocompounds all ONE rewards every hour for you. It is also more tax efficient, as in traditional staking, you create a taxable event every time you collect and compound your rewards.

Instantly Swap for ONE

Additionally, you can become a liquidity provider for the stONE/ONE pair, allowing you to earn trading fees and rewards while creating a liquid market for this trade.

Collateral and Lending

How It Works

The exchange rate for stONE to ONE will gradually increase over time as staking rewards are earned. At a later date, the user can burn their stONE to start an undelegation process and receive their original ONEs plus the earned rewards. The Tranquil protocol takes a 10% fee from the earned rewards.

Please visit our project docs for more details.


While our short term goal is the smooth and stable launch of stONE to validate the system and gain traction, we have an incredibly ambitious roadmap for the project.

Build Utility for stONE

A more close term target is building liquidity for the most common trading pairs, so stONE holders can smoothly perform trades with low slippage without having to swap to ONE.

Validators and Decentralization

We also realize this job is probably too great for us alone, and we will work very closely with both the community and Harmony team to help the entire network prosper.

Mainnet Launch

Additionally, Tranquil will offer an incentivized stONE-ONE pool for Sushiswap, as well as an incentivized stONE lending/borrow market. You will be able to earn extra rewards for stONE on top of the normal staking rewards!
