An order book for perps and futures.
For traders and algorithm builders, by invitation: orders match by fixed price and time rules, and every fill carries a proof.
One interface for crypto and futures, across SOL and EVM. Train an algorithm on past windows and replay it until it holds. Then dispatch it to the Taifoon book on chain, or to Kraken, Interactive Brokers or Polymarket. One decision, any outlet.
01Participants
One book. Every participant.
The book is the same for all. Only the way you reach it changes.
Direct
Place and cross the book yourself. The price is checkable and the fill settles on chain.
Liquidity
Quote both sides. Price-time priority rewards depth that rests on the book.
Programmatic
One signed request places an order. It clears against the same book as everyone else.
Autonomous
Drive orders from a model or a script, rehearsed first on a replay of any window.
02Why the book
Settled, proven, reproducible.
Every order meets the same book under price-time priority. Each fill carries a proof you can check.
01
One interface
Crypto and futures, SOL and EVM, behind one book, one chart and one ticket. No hopping between venues.
02
Train and backtest
Replay any past window and rehearse an algorithm before it trades. The same inputs give the same result on every run.
03
Dispatch anywhere
Settle on the Taifoon book, or route the order to Kraken Futures, Interactive Brokers or Polymarket. One decision, any outlet.
03Markets
Open a market.
Each market opens on its chart, its book and its ticket. Crypto perpetuals and index futures share one ticket.
04Fees
Fees have two layers.
A trading fee in basis points falls with your 30-day volume. Settlement gas is charged at cost. A negative maker fee is a rebate.
| Tier | Volume | Taker | Maker |

05Optional layers
The book stands on its own.
Intelligence overlays and bridges to outside venues attach on top of the book. Each is a separate product you turn on. None of them is the default.
| Layer | What it adds |
|---|---|
| Kraken gateways | A hosted gateway that routes your order to Kraken Futures |
| Session calendar | When each futures market trades |
| API key | Sign a request and place an order from code |
| Free access | Redeem an access code |
| Protocol docs | Matching, settlement and the proof on a fill |
