Integrated availability data availability via Arbitrum, Optimism, Polygon, StarkWare, and ZkSync

These chains include Arbitrum, Optimism, Polygon, StarkWare, and zkSync. Users can opt in or out of using Avail for data availability. This is a necessary service for these “rollup networks” to hide the large amounts of data generated by every transaction that occurs. A key driver of DA solutions is that they can provide a cheaper and faster way to store data than the main Ethereum blockchain.
