Example: If a user completes their 90th qualifying day on April 10th 2026, their reward will be unlocked on that date. Each tier is tracked independently. Users may unlock greater reward amounts if they reach and maintain higher tiers later within the campaign window. Example: If a user deposits $1,000 on Day 1 and qualifies for that tier, then later deposits an additional $3,000 on Day 10, they will unlock both Tier 1 and Tier 4 if both tiers meet the 90-day AUM rule.
