Ethereum's Shift from Execution Layer to Settlement Layer

The growth of crypto perpetual futures is transforming Ethereum's role in market structure.

As traders seek low latency and deep liquidity, they are migrating to layer-2 networks like Arbitrum, Optimism, and zkSync. These protocols handle order matching and execution, while Ethereum secures the final state.

The arrangement solves the UX problem without requiring Ethereum to match the performance of Solana or Sui. The payoff for traders is sharper: sub-cent fees and confirmation times measured in milliseconds on some L2s, while still benefiting from Ethereum's deep liquidity pools and battle-tested security.

Ethereum loses direct fee capture when perps volume migrates off mainnet, but it earns less per transaction on the immediate count. Instead, it strengthens its long-term moat by feeding a whole ecosystem of application-specific chains that pay for security.
