Two readings, side by side
Lighter 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
Lighter
N33BQEX6ZYVM Lighter's Standard account charges 0.000% maker and 0.000% taker, read on their own docs 3 Sep 2026 — there is no fee left for a discount to cut. What the link adds is your first week of Premium fees rebated, to your first $10M of volume. We receive 10% of referred users' fees (Bronze tier; higher tiers exist). The restricted-country list is still Lighter's; payment does not rewrite it.
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 — Lighter 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 Lighter 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.
