The Grass project airdrop incentivizes early participants by rewarding them with tokens based on their contributions and engagement. The allocation mechanism prioritizes active users, such as those providing data, running nodes, or participating in governance. By distributing tokens proportionally to effort and involvement, Grass ensures fair recognition of early supporters. This approach not only fosters loyalty but also encourages continued participation, driving ecosystem growth. Additionally, tiered rewards and vesting schedules help maintain long-term commitment, balancing immediate incentives with sustainable development. Overall, Grass's airdrop strategy effectively aligns early adopters' interests with the project's success.
