Scroll vs Arbitrum L2 Fees

**Scroll** and **Arbitrum One** are popular Ethereum L2s with low fees. Both inherit L1 security via rollups, but differ in proof systems, ecosystem maturity, and bridge UX.

Step by step

1. List your protocols

DEX, lending, and NFT venues may exist on one chain only.

2. Benchmark weekly spend

3. Plan L1 exits

Canonical withdrawals can take days; factor opportunity cost.

Scroll vs Arbitrum

  • Scroll: zk-rollup design; growing ecosystem; check bridge routes.

Common mistakes

  • Bridging to wrong address format
