About Arbitrum
Arbitrum One is an optimistic rollup that batches Ethereum transactions and posts proofs to Ethereum mainnet, inheriting security while offering 10–30× cheaper execution. Block times are sub-second inside the rollup; withdrawal to L1 takes ~7 days due to the optimistic challenge window (a swap sidesteps this by paying out natively, not by bridging).
