How this service works
Hot volume is often fake. This reads a token's transfer events and flags the wash/circular shape: the share of transfers round-tripping through addresses active on BOTH the send and receive side, plus participant concentration. Returns clean / elevated / likely_wash with the top round-trippers. A heuristic signal, not proof — LPs and routers legitimately sit on both sides — so size off it, don't convict on it. Pass days= (default 7). Not financial advice.
Output
Returns a classification label (clean, elevated, or likely_wash), the share of transfers identified as round-tripping through addresses active on both send and receive sides, a participant concentration metric, and a list of the top addresses involved in circular transfer patterns. The result is a heuristic signal intended for risk sizing, not definitive proof of manipulation.
Example use cases
Pre-trade token volume validation
“Before I buy into this token at 0x6982508145454Ce325dDbE47a25d4ec3d2311933, can you check whether its trading volume looks organic or if there's wash trading going on over the past 14 days?”
DeFi portfolio risk screening
“I'm holding a position in the token at 0x912CE59144191C1204E64559FE8253a0e49E6548 — can you scan for wash trading patterns over the last 30 days and tell me if the volume is suspicious?”
New token listing due diligence
“We're considering listing 0x4d224452801ACEd8B2F0aebE155379bb5D594381 on our platform — can you analyze its transfer history for circular trading or wash volume over the past week and show me the top round-tripping addresses?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/wash-trading?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, heuristic signal about whether a token's transfer volume has wash trading characteristics before trading or listing decisions. It is preferable over raw block explorer lookups when you want a pre-computed classification and ranked round-tripper list rather than raw event data. Pair with Volume Authenticity Check for corroborating signals. Not suitable as sole evidence of manipulation — treat the output as a risk sizing input.
Side effects
- Invalid or non-existent token contract address returns an error
- Days parameter exceeding 30 causes a validation error
- Token with insufficient transfer history may return inconclusive results
- Legitimate LP and router addresses may inflate round-trip signals causing false positives
- Network congestion or RPC issues may cause timeouts
