Hackathon participants should consider each one of the stages of onboarding: How is the project enabling users to earn free tokens simply and easily in Telegram? What are the referral mechanics so new users can share the project with their friends? Does the project have step-by-step onboarding into their products so users can learn to use them by exploring? What incentives should they provide to make their liquidity pools the most attractive to traders?

It's crucial for projects participating in The Open League Hackathon to consider the implementation of their own token within the TON ecosystem, as we are keen on stimulating liquidity pools and offering financial rewards to those who provide liquidity. This approach is designed to enhance the project's ecosystem by ensuring better liquidity management and incentivizing user participation through rewards.

By combining accessibility for new users and depth for experienced ones, projects should leverage Telegram Mini Apps to provide secure and permissionless financial services, promoting financial freedom and inclusivity.
