Yeah, incentive didn't always relate to giving away your token. I have also participated in some projects based on arbitrum that have even issued their arbitrum future tokens and these tokens can be exchange for the real arbitrum once arbitrum launch its own token. These projects were using arbitrum futures token as incentives too. since you were based on arbitrum and it would be so good if you were trying to reach arbitrum to make a partnership with it or at least have some projects that launched in arbitrum as your partner.

I hope that you can get what you want from there. good luck.
