Arbitrum OneArbitrum Nova
An Ethereum optimistic rollup operated by Offchain Labs — the largest L2 by TVL.
Arbitrum One inherits Ethereum L1 security via fraud proofs and a 7-day challenge window for withdrawals. It hosts the largest stablecoin yield surface outside L1: Aave v3, Compound v3, Pendle, and GMX-adjacent strategies. See Optimistic rollup.
