Each user can get the 100% rewards to a maximum of 1,000 RLUSD holdings, with a validity of 7 days.

The total reward pool of event 1 is 100,000 RLUSD, Rewards will be distributed on a first-come, first-served basis based on the order of users’ initial holdings of RLUSD. Once you receive the 100% reward quota, you will be guaranteed that reward for 7 days.

3. Reward Distribution: Accrued rewards, if any, will be deposited into the user's Funding Account at the intervals specified on the event page.
