Definition ∞ Rollup transaction volume refers to the total number of operations processed on layer-2 scaling solutions known as rollups. These solutions batch multiple transactions off-chain and then submit a single, compressed proof to the main blockchain, significantly increasing throughput and reducing costs. High rollup transaction volume indicates effective scaling and active usage of decentralized applications on these secondary layers. It serves as a key metric for layer-2 adoption.
Context ∞ The current discussion around rollup transaction volume often centers on its role in alleviating congestion on mainnet blockchains, particularly Ethereum. Growing volumes on rollups signal successful scalability efforts and a shift in user activity towards more efficient environments. A critical future development involves the continued growth and interoperability of various rollup solutions, further distributing network load and making blockchain interactions more economical for a global user base.
