Layer-2 (L2) solutions are transformative technologies built atop primary blockchain layers (layer-1) to enhance scalability, speed, and cost-efficiency. By leveraging innovations like rollups and sidechains, L2 networks address the limitations of layer-1 blockchains—such as Ethereum’s 15 TPS bottleneck—while maintaining security and decentralization. Below, we explore the 10 most promising L2 projects poised to shape the crypto landscape in 2025.
1. Polygon (MATIC)
