HyperBasis monitors a pool of 282 known institutional and whale wallets on Hyperliquid and turns their position changes into flow intelligence.
1. What is tracked
Position snapshots — every 30 minutes, the current positions of every wallet in the pool are captured per instrument.
Flow events — increases and decreases between snapshots, with direction and size.
Concentration — how much of an instrument's open interest sits in the tracked pool.
2. Where the pool comes from
The pool is a curated set of 282 addresses assembled from public on-chain parsing and known Hyperliquid large-trader activity. It is a sample of the large-trader population, not the entire population — and HyperBasis says so explicitly in the product.
3. Honest limits
Pool coverage: the 282 addresses do not cover every large trader. Flow from untracked wallets is invisible to this feature.
Attribution: wallets are pseudonymous. HyperBasis does not claim to know who owns an address; it only reports what the address does.
RWA positions: the pool holds real RWA perp positions (equities, FX, commodities, indices); instruments with no pool positions show N/A honestly.
4. How to use it
Whale flow is context, not a signal by itself: combine it with deviation, funding alignment and capacity before acting. The HyperBasis Terminal's LARG page renders the flow feed; the API exposes positions, addresses and flow events under /api/v1/whale/*.
Honest-limitations policy. HyperBasis labels every data gap instead of hiding it. Where a source does not exist (e.g., zero-volume Hyperliquid instruments that never traded), the product shows N/A rather than fabricated values.
