Network Activity and Adoption: High transaction volumes indicate active network usage and suggest that the network is handling a significant number of transactions, which typically reflects higher user adoption and integration. For instance, Layer-2 networks such as Arbitrum and Base are dominating their ecosystem, accounting for a substantial percentage of the transaction volumes across multiple L2 networks1.

Scalability and Efficiency: L2 solutions aim to alleviate the load from Layer-1 networks by processing transactions more efficiently. Increased transaction volumes on L2s prove their capability to handle more transactions than Layer-1, as seen with Ethereum's L2 networks processing up to 2.5 times the transactions occurring directly on Ethereum2. This capability underscores the scalability benefits of L2 networks.

Cost Implications: Transaction volumes can impact fees. Since L2 networks are designed to reduce costs associated with transactions, high transaction volumes could lead to lower average transaction fees, thereby making the network more attractive for larger-scale operations and microtransactions32.

Economic Activity and Usage: Transaction volume can be used as a proxy for economic activity on the network. Networks like the Bitcoin Lightning Network use this metric to demonstrate faster and cheaper transactions than the Layer-1 network, crucial for enabling decentralized finance (DeFi) applications4.

Market Confidence: Consistently high transaction volumes might signal confidence in the network from both users and developers, indicating that the network has robust security, performance, and reliability to attract regular use5.
