Today's episode with Matt from Caldera explores how Rollup-as-a-Service providers are dramatically reducing the cost and complexity of launching L2s, from $15M down to just thousands. Learn about Caldera's strategy for standardizing blockchain infrastructure, their perspective on different rollup stacks (Arbitrum, Optimism, zkSync), and their vision for connecting multiple blockchain clusters through their meta layer.
