Who is actually trading on Trade.xyz?
Arrakis follow-up to its earlier "Who's trading on HIP-3?" piece, this time using deterministic Hyperliquid order-metadata tags (TIF, builder code, fill flag, hold time) to mechanically classify every wallet across the four Trade.xyz markets (xyz:CL, SILVER, TSLA, XYZ100) over March 10–31, 2026: 79,622 wallets, $51.95B total volume.
Key finding: the sybil layer inflated wallet count, not dollar throughput. The "Airdrop Farmer" bucket holds 35,091 wallets (44% of users) but generated only $0.40B (0.77% of volume). 99.9% of those farmer wallets trace back to a single Polymarket operator ("Themino") running 70 chains of 34,553 wallets through a baton-pass farm — using HL's $1 internalTransfer primitive, each wallet runs a 5-step sequence in ~26 seconds. Total fees Themino paid: $34,510.
Real volume comes from identifiable books. Market makers: 363 wallets (0.46%) carried 63% of volume ($32.75B). The #2 MM ("Powell") is a Polymarket user running multi-market quoting. Jump Crypto ($3.15B), Selini Capital ($1.03B across 3 wallets — two MM, one HFT), Wintermute ($230M) all visible. Builders split into algorithmic (Tread.fi, Origami — replaced wash-trading with retail market-making, now populate top-of-book on nights/weekends when traditional MMs aren't quoting), wallet-integrated (Phantom, MetaMask, Rabby — $1–3K median per wallet), and apps (Insilico, hypurrdash, etc — fewer wallets, higher per-wallet volume). Retail: 22% of top-400 retail volume ($1.63B) is verifiable Polymarket users. Total Polymarket footprint across MM+SAT+retail on Trade.xyz: ~$6B. Kraken dominates CEX-funded retail; Hyperunit + deBridge dominate bridge-funded.
Conclusion: layered answer to the sybil debate. Yes there's a sybil layer (predictable pre-TGE). No evidence of separate high-volume wash-trading. Real volume runs through identifiable professional desks + a Polymarket-overlapping retail base.
