Layer 2 solutions, such as Optimistic Rollups or zk-Rollups, help Ethereum restaking platforms scale by offloading transaction processing from the main Ethereum chain. This reduces congestion, minimizes gas fees, and enhances transaction speeds. By using these solutions, restaking platforms can handle more users and higher transaction volumes without compromising performance. Layer 2 also enables more efficient smart contract execution, allowing Ethereum to scale while maintaining security and decentralization.
