ArbitrumDAO puts real power in the hands of its community. It governs one of the most active and liquid blockchain networks, processing billions in monthly transaction volume and controlling a vast onchain treasury. Unlike protocols where decisions rest with a foundation or core team, ArbitrumDAO empowers its community to make binding calls on everything from protocol upgrades to treasury spending. 

Decentralized governance thrives on participation, and in ArbitrumDAO, it’s never been easier to get involved. You can spend a few minutes reading and discussing Forum posts, delegate your voting power, take on the role of an active delegate, apply for grants to build ecosystem projects, or contribute professionally to organizations advancing Arbitrum’s mission. That’s what makes ArbitrumDAO unique: there’s a place for every kind of contributor, and together, these roles reinforce one another, creating a resilient ecosystem and one of the strongest models of decentralized governance in action.

Below, we'll walk through each of these roles in detail: what they involve, how to get started, and what you can expect as you grow your participation.
