}HIP-3 Backstop
Raw fills absorbed by the backstop of a dex
Paginated stream of fills executed against the backstop address of a HIP-3 dex. These are positions absorbed by the backstop strategy following liquidations not covered by the order book.
Pagination. has_more is set to true when len(data) >= limit (heuristic, no COUNT(*)). Use offset to walk the stream.
Latency. ~170 ms.
