# 8.3 Ecosystem Contribution

Trust Rank is based on usage history, while long-term contributions and actions will be evaluated as Ecosystem Contribution.This feature is planned for future implementation.

**Evaluation factors (planned):**

* NFT holding duration (esp. Genesis, OG, and higher rarities.)
* Staking of SFT or NFTs
* Spending of EVT/Econ (breeding, upgrades, lifespan recovery, etc.)
* Contribution to LP/liquidity pools
* Other metrics (to be announced)

**Reflections:**

* Preferential SFT distribution
* Eligibility for exclusive airdrops

👉 Trust Rank = “daily trustworthiness,” while Ecosystem Contribution = “long-term commitment.”

**Implementation schedule:**

* Ecosystem Contribution will be rolled out **gradually after Mainnet Beta (Open Beta Version) launch**.
* Detailed evaluation items will be announced in GitBook updates.
* Contribution reflection will begin **at an officially announced timing**.
