Volume Guard

Bounds on routed trade size and on rolling routed volume, per market and per wallet.

RISKEXECUTIONruntime moduleunaudited
01

Behavior

  • Before-callbacks deny trades whose deterministic estimate exceeds the configured size.
  • After-callbacks re-check the amount Pump actually executed and fail the whole transaction if it exceeds the guard.
  • Rolling window (up to 7 days) for market-wide and per-wallet routed volume.
Limitation. Counts routed volume only; trades made directly on Pump are invisible to the guard.
