Two readings, side by side
Hyperliquid vs Ostium
Not a scoring table. Two dated readings of the venues' own restriction pages, the countries where their lists differ, and each programme's declared terms — quoted, never improved.

What each programme declares
Hyperliquid
FUT You get 4% off fees for your first $25M of volume. Hyperliquid's entry tier is 0.045% taker and 0.015% maker, read on their own docs 3 Sep 2026, so on taker volume the discount keeps 0.0018% — about $18 per $1M; on maker volume it is 0.0006%. We receive 10% of the referred fees, out of that fee rather than on top of yours. Restricted Persons are still theirs; payment does not rewrite the list.
Ostium
M810X Ostium's opening fee is 3–10 bps depending on the asset, read on their own docs 3 Sep 2026. We record no invitee discount for their programme. We are paid a referral commission. The restricted-country list is still Ostium's; payment does not rewrite it.
Questions
Which can I use from my country — Hyperliquid or Ostium?
The venues decide that, at KYC. What we publish is a different thing: whose list names which countries — yours marked when the connection can be placed — and the click is checked at the edge either way.
Do Hyperliquid and Ostium pay the same referral reward?
Each declares its own programme; both are quoted above verbatim and checked monthly. We add nothing to either.
Why do the two lists differ?
Different legal exposure, different regulators, different lawyers. We do not guess at reasons — we date what each page says and record every later change in the ledger.
