Collective Trust Tiers are the very first step towards establishing a connection between one’s positive impact in the ecosystem and access to different types of work, grants, and roles within the Collective.

**Initially, Trust Tiers will be used to:**

- Establish transparent standards for contribution and grant eligibility, specifically:
  - Determining appropriate grant sizes for grants made by the Grants Council
  - Determining funding eligibility for different Alliances proposing [Missions](https://gov.optimism.io/t/token-house-missions/5881/2)
  - Specifying which Alliances may apply for [Foundation Missions (RFPs)](https://github.com/orgs/ethereum-optimism/projects/31/views/1)

- Help people understand the types of contributions (and, over time, Attestations) we think are important for establishing the basis of reputation in the Collective
