# How To **DNOD TMA Gameplay: Simple and Rewarding** The DNOD TMA offers an engaging and straightforward gameplay experience designed to help you earn coins and boost your harvesting rate—crucial for maximizing your rewards during the DNOD token airdrops. Here’s how you can make the most of the app: **Vaults** Vaults are the core feature of DNOD TMA, each with its own cost and specific harvesting rate per hour. By upgrading your vaults, you can significantly increase your harvesting rate. The more you invest, the more you earn, creating a cycle of growth and opportunity. Some vaults come with unique conditions that must be met before you can upgrade them. Keep in mind that these conditions and the vaults’ parameters will change with each reset cycle, adding a strategic element to your gameplay. **Missions** Missions are another way to boost your earnings. Regularly available, these missions are easy to complete and offer free coins as rewards. These coins can then be reinvested into vaults to further enhance your harvesting rate, making missions a quick and efficient way to accelerate your progress. **Invites** Inviting friends to join DNOD TMA is not only a generous gesture but also a smart strategy for earning extra coins. Each successful invite rewards you with a substantial amount of coins, which can be used for upgrades. Additionally, by helping your friends explore the DeFi space, you're building a community. When the full DefiNodal app launches, both you and your friends will have the opportunity to participate in the project’s earnings and governance, making it a win-win situation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
