So far some of the pure onchain ways and incentive mechanisms are
1) @agentcookiefun : DM people and shaemlessly request them to engage with your announcement
2) @qrcoindotfun : Get attention and your launch tweet or product page.
3) @kaitoai : Incentive for people to talk about your product.
4) @noiceapp : Incentives for people to engage with your launch tweet
