Case Study

Treasury rebalance on Base

A mid-sized treasury rebalance shows the classic bracket pattern: a price jump before inclusion, a worse fill for the victim, then an immediate reversal after the block.

Trade size

Victim output

Observed loss

$120

Victim trade sits between two same-direction then unwind swaps on the same venue.
Execution worsens relative to the pre-submit quote despite no large external move in the surrounding window.
The post-trade price partially reverts immediately after the victim is filled.

Fair-ordering replay

Replay output

Residual loss

$12

Recovered value

$108

The user trade is preserved in a deterministic order rather than being bracketed by a profitable attacker sequence.
Residual loss reflects normal AMM price impact rather than sequencing discretion.

This is the exact kind of high-value treasury flow that can justify a protected pilot before full sequencer integration.
