<p>Power-law fits of trading activity for SC-SC transactions, where both sender and receiver are SC.</p>

Plotted on log-log scales, these subfigures display the empirical distributions of trade frequencies alongside their power-law fits. The vertical red dashed line marks the upper threshold, derived by KS distance, beyond which the empirical data begins to deviate from the power-law fit.

These plots highlight the behavior of highly active, automated contract-to-contract interactions, often marked by heavy tails, high thresholds, and variability across time. Such patterns reflect systemic processes or protocol-level dynamics in SC ecosystems.</p>
