Layer-2 networks such as Arbitrum, Optimism, Base, and zkSync now process a large share of Ethereum activity, often settling transactions for a few cents instead of several dollars. Total value locked across leading L2s has grown into the tens of billions.
By bundling many transactions into a single proof posted to Ethereum, rollups deliver speed and low cost without sacrificing the security of the base chain. For users, this means faster swaps, cheaper transfers, and a smoother on-chain experience.
Data points are approximate and change rapidly.
