Layer 2 · Ethereum
Optimistic rollup that settles Ethereum transactions at lower cost.
Aragon provides contracts and tooling for running an organisation on-chain: a permission system, proposal and voting plugins, and a treasury. Its plugin architecture lets a DAO change how it governs itself without redeploying, which matters because governance requirements rarely survive first contact with a real community.
