What venues ask for before you trade

The row that matters most on this site, because the first column is the admission test. Sign-in is what the venue's own onboarding page describes; the documents column quotes what its terms say about identity checks, which is not always the same thing as the marketing page.

Mechanism named — the venue writes down how deposits are checked Right reserved — the terms allow a check without describing one States none — the documentation says access needs no approval Nothing published — neither the terms nor the docs say either way

Who may open an account is settled in each venue's terms, so read the ones that cover you. Every door and every clause above was read on 18 September 2026 in the venue's own pages. The test is applied to those pages rather than to the cell that summarises them, and one row shows why that matters: Paradex's sign-in cell records the signature route its account is derived from, while the wallet overview the cell was taken from also describes an embedded wallet opened from an email or a social account. That second route is what puts Paradex on the right-hand side of the figure above. Wherever a venue's own onboarding pages document a way in of that kind — an email, a social account, or a wallet the venue opens for the trader — the venue is outside the register, however cheap it is and however deep its book. A marketing page and a terms-of-use page rarely say the same thing in the same words, and when they disagree here the clause is the one quoted. Who a venue will deal with also depends on where you are, so find the terms that cover your own country before any money moves.

Four rows, because the board on this page is the register and the register is four entries long. Ten venues on this desk have an order book we could sample and a published fee schedule, and all ten carry a mark against the same five headings; the six missing here document a second door, so their marks are printed on the method page instead, where the boundary can be read against numbers rather than taken on trust. The door figure at the top of this page is where each of the sixteen is placed on one side of that line or the other.

The bar beside each score is that score against the full scale, not against the venue above it. Open interest is the venue's own return, as CoinMarketCap listed it on 22 September 2026; What each criterion is worth, and how it is worked out, sits on how we score.

The onboarding terms come from the venues. This figure does not: each bar is the median value of resting orders within 10 basis points of the mid price on the BTC perpetual, both sides of the book, across every successful snapshot.

Each bar stands on 56 readings of that venue's own book, taken on 19 September 2026, ten minutes between readings, beginning just after midnight UTC. A venue priced against an oracle keeps no resting book to read, so none of them is filed in this figure.
