Scroll is an Ethereum layer-2 network that uses zero-knowledge rollup technology.
Arbitrum is an Ethereum layer-2 network that batches transactions with optimistic rollup technology and settles them on Ethereum.
Both Scroll and Arbitrum use ETH for network fees, so the same asset can cover gas on each side. Keep a small balance of ETH on Scroll for the transaction and on Arbitrum for whatever you do after arriving.
