This is paired with 3-5% swap fees that "aggressively discourage wash-trading and manipulation." + +The mechanism works because: +1. Moving price requires swaps that pay the high fee +2. The liquidity weighting means manipulation attempts when liquidity is high are both expensive (large swaps needed) and heavily weighted in the final calculation +3. The fee revenue accrues to LPs, creating a natural defender class that profits from manipulation attempts + +The proposal explicitly contrasts this with CLOB vulnerabilities: "With CLOBs there is always a bid/ask spread, and someone with 1 $META can push the midpoint towards the current best bid/ask" and "VWAP can be manipulated by wash trading." + +This is rated experimental rather than proven because the mechanism has not yet been deployed or tested against real manipulation attempts.
