Every Spark liquidation, with the bonus it actually paid
One row per LiquidationCall: amounts scaled by token decimals, oracle prices at the liquidation block, the bonus the liquidator realized, and the bonus the protocol was configured to pay. The gap between those two is the filter, not a research project.
The liquidation dataset isn't available right now
The warehouse didn't answer. Nothing here is estimated, so the page waits rather than guessing.
