On August 31, 2021, Arbitrum went live on mainnet! This means it’s available to migrate funds and begin using the many DeFi apps that have already launched on the Layer 2 Rollup scaling solution.

**Harry Kalodner** and **Steven Goldfeder** return to *State of the Nation* to discuss what this means for the crypto space. Gas Markets, onboarding directly to Layer 2, the user experience, and the march towards decentralization are all themes. Layer 2 Summer is still intact!
