  "description": "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.",
