How Swap Volume and Gas Fees Impact CBDC Exchange Costs | HackerNoon
Briefly

The article evaluates the performance of L2-L3-Exchange versus L1 Mariana in handling transaction costs using simulation outcomes. Key findings suggest that L2-L3-Exchange is more efficient for small and large transaction volumes, mainly due to its strategic minimization of gas fees. The study illuminates the dominance of gas fees in smaller transactions and the influence of price impact in larger ones. Detailed figures illustrate the variances in costs based on transaction volumes and gas fee scenarios, supporting the conclusion of L2-L3-Exchange's competitive edge due to its innovative liquidity management and operational efficiencies.
The results indicate that L2-L3-Exchange consistently outperforms L1 Mariana, particularly for transaction volumes of 10k and 1mn, primarily due to minimized gas fees.
Gas fees dominate the costs for smaller transactions in L1 Mariana, while for larger transactions, the price impact becomes the main driver of total swap costs.
