Earned Liquidity rewards are linearly claimable with the target deposit. For example, Luke's contribution requirement to earn the full MANTA rewards is 100 DOT. If he deposits 50 DOT into MantaPay over the course of the event, he will be able to claim 50% of his rewards. The deposit rewards are cumulative over the event period. In other words, Luke can deposit 50 DOT on day 1 of the event, and 50 DOT on day 10 of the event, and it will count as a total 100 DOT deposited during the event, which unlocks the full 100% of his rewards.
