Arbitrum Casinos
Optimistic rollup L2, growing casino adoption
Arbitrum is an optimistic rollup L2 on Ethereum and one of the two major rollup networks (alongside Optimism) that crypto casinos are integrating in 2025-2026. Deposits clear in roughly one second for fractions of a cent, and the chain hosts the same ERC-20 stablecoins as mainnet at dramatically lower cost. Casino adoption is broader than Optimism's but narrower than Polygon's. We flag operators that accept Arbitrum-USDC natively rather than routing through a bridge, which is the distinction that matters most.
