Networks, Rollups & Ecosystems

Network coverage is where Castle Labs connects protocol design to ecosystem outcomes. We write about L2 economics, sequencer and data-availability tradeoffs, incentive design, consumer-app bets, and the strategic positioning of ecosystems like Arbitrum, Starknet, Mantle, MegaETH, and Base. This lane matters to foundations, protocols, investors, and builders because the question is no longer whether blockspace can scale; it is which networks can turn scale into durable demand.
