Root + Impact

Description

• Sellers who have completed multiple NFT sales must call collectUsdcFromSelling individually for each listing. During periods of elevated gas prices, the fixed per-transaction overhead becomes a meaningful economic burden, and the repetitive manual process is a poor user experience compared to the batch-friendly interfaces common in production NFT protocols.

Recommended Mitigation

Add an optional batchCollect helper that iterates over a caller-supplied array of listing IDs, delegating to the existing collectUsdcFromSelling logic and inheriting all its guards.
