Renzo (REZ) is used in several key ways within the Renzo protocol:

1. Governance Voting: REZ tokens are used to vote on governance proposals, which cover various aspects of the protocol, such as risk management, deposits, collateral assets, operator whitelisting, and treasury management.

3. Staking and Yield Enhancement: By using Renzo, users can maximize their returns compared to traditional staking methods. The protocol manages operator nodes and distributes rewards based on the staked assets.

4. Community Engagement: REZ tokens are allocated to community campaigns, including the ezPoints Campaign, which incentivizes users to participate in the ecosystem.

Overall, Renzo (REZ) plays a central role in managing the protocol, enhancing yields, and promoting community engagement.
