When can I unstake O3 ?

Staked O3 is not available to unstake until the next mining period

  • Ice Age Mining (Ethereum): After 500,000 Ethereum blocks (around 10 weeks).

  • Ice Age Mining (BSC): After 1,600,000 BSC blocks (around 8 weeks).

  • Ice Age Mining (HECO): After 1,600,000 HECO blocks (around 8 weeks).

How to claim the staking rewards?

All mining rewards are in a locked state.

  • On the Ethereum, you need to provide the O3/USDT trading pair on Uniswap V2 and stake the UNI-LP to unlock O3.

  • On the BSC, you need to provide the O3/BUSD trading pair on PancakeSwap V2 and stake the CAKE-LP to unlock O3.

  • On the HECO, you need to provide the O3/HUSD trading pair on MDEX and stake the HMDX-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.
