Evidence
The figures behind the verdict, as the engine served them.
An averaging oracle makes an attacker outweigh genuine trading as well as move the book. A market with no genuine volume has no such defence.
- Cost of a 50% move, order book only
- 0 USDC
The target is reachable through the order book
- Genuine volume in the oracle window
- 0 USDC
Over the last 900 seconds (15 minutes), after the genuine-trade filter
- Cost against genuine volume
- not computed
Below 1, moving the price is cheaper than all genuine trading across the window. Not computed when there was no genuine volume or the target is unreachable
- Total attack cost
- 0 USDC
The move, plus the genuine volume an averaging oracle forces an attacker to outweigh
