## When can I unstake O3 ?

Staked O3 is not available to unstake until the next mining period **(after 500,000 Ethereum blocks, around 10 weeks).**

## How to claim the staking rewards?

All mining rewards are in a locked state. you need to provide the O3/USDT trading pair on Uniswap and stake the UNI-LP to unlock O3. 

You can claim the O3 rewards whenever you want. However, the more frequently you claim, the longer it takes to unlock. We recommend holding longer and claim all in once.
