A little more clarity
Good questions.
Clear answers.
Where do the rewards come from?+
Each pool distributes SAPPHIRE supplied by the team before the reward period. Rewards are shared in proportion to stake. Deposits are not lent out or used in an external yield strategy.
Is this computer mining?+
Sapphire Mine is a mining-themed staking interface. Your computer does no mining work. Keeping the page open or clicking more often does not increase rewards.
How much can I earn?+
Your reward rate follows your share of the selected pool. The SAPPHIRE pool shows token APR; ETH and USDG pools show SAPPHIRE emissions per day. Rates change with participation and stop when the funded period ends. Token rewards do not guarantee a dollar profit.
Can I withdraw at any time?+
There are no protocol lockups or cooldowns. Withdraw your original asset and claim accrued SAPPHIRE separately, or use Exit all to do both in one transaction. Transactions require ETH for gas.
What should I know before staking?+
The contracts are experimental and have not been independently audited. Smart contracts and tokens carry risk, and SAPPHIRE’s market value can change. Use a wallet that supports Robinhood Chain and review each transaction before signing.
