What this hub covers
Crypto derivatives are contracts whose value derives from an underlying crypto asset — Bitcoin, Ether, or any other token. The dominant product is the perpetual swap (perp), a leveraged contract with no expiry date that uses periodic funding payments to track spot prices. Alongside perps, quarterly futures provide calendar-structured exposure and basis-trading opportunities, while options on platforms like Deribit offer defined-risk strategies unique to coin-settled markets. This hub covers all three product families: the funding mechanic that makes perps work, the liquidation infrastructure that enforces margin discipline, the open-interest signals that reveal market positioning, and the risk-management frameworks you need before adding leverage to crypto exposure.
Key principles
- Funding rates are the anchor: Perpetual swaps never expire, so exchanges use 8-hourly funding payments between longs and shorts to keep the contract price near spot — monitoring funding cost is mandatory for any leveraged position held overnight.
- Mark price, not last price, triggers liquidations: Exchanges derive a mark price from a multi-exchange spot index plus a decay of the funding premium, preventing a single illiquid print from cascading into mass forced liquidations.
- Open interest reveals conviction: Rising price plus rising OI is a stronger trend signal than rising price with falling OI; the latter suggests short-covering rather than new long conviction.
- Basis trades are market-neutral yield: Long spot plus short futures locks in the futures premium as annualized yield when the basis converges at expiry — the risk is early convergence or exchange failure, not directional price movement.
- Coin-settled options have convexity risk: A long call on Deribit that expires in-the-money pays out in BTC — when BTC falls, your USD-denominated profit shrinks even if the option finished in the money.
- Cross margin magnifies knock-on risk: Under cross-margin mode, unrealized losses in one position eat into margin for all other positions in the same account — an isolated-margin approach limits contagion to the position itself.
- Leverage and liquidation distance are inversely proportional: At 10x leverage the liquidation is approximately 9% from entry (before fees); at 25x it is roughly 4% — crypto volatility can bridge that distance in minutes during high-impact events.
- Exchange risk is non-trivial: Crypto derivative positions are unsecured creditor claims against the exchange — exchange insolvency, withdrawal freezes, and socialized-loss programs are live risks with documented precedent (FTX, Bitmex, early OKEx incidents).

FAQ
What is a perpetual futures contract in crypto?
A perpetual futures contract (perp) is a derivative that tracks an underlying asset's price without an expiry date. Unlike quarterly futures, perps never settle — traders hold them indefinitely. To keep the perp price anchored to the spot price, exchanges run a funding rate mechanism: longs pay shorts (or vice versa) every 8 hours when the contract trades at a premium or discount to spot.
How does the funding rate mechanism work?
Funding is a periodic cash transfer between longs and shorts, typically every 8 hours. When the perp trades above spot (positive funding), longs pay shorts to compensate them for holding the position. When the perp trades below spot (negative funding), shorts pay longs. The rate adjusts continuously based on the premium or discount between the perp and an index price, keeping the two anchored over time.
What is the mark price and why does it matter for liquidations?
The mark price is a fair-value estimate computed from multiple spot-exchange index prices and the funding premium, rather than just the last traded price. Exchanges use the mark price — not the last traded price — to determine unrealized P&L and trigger liquidations. This prevents large traders from artificially moving the last-traded price on a thin order book to force liquidations of other traders.
What is basis trading in crypto?
Basis trading captures the premium (basis) between a futures contract and the spot price. A classic cash-and-carry trade buys the spot asset and simultaneously shorts an equivalent futures contract, locking in the basis as yield when futures expire at spot. The annualized yield is: (futures price − spot price) / spot price × (365 / days to expiry) × 100.
What does open interest tell you about the market?
Open interest (OI) measures the total number of outstanding derivative contracts that have not been settled. Rising OI alongside rising price suggests new money is entering on the long side — typically a bullish confirmation. Rising OI with falling price suggests new short positions are being built. Falling OI during a price move indicates existing positions are being closed rather than new ones opened, which can signal weakening conviction in the move.
How do crypto options differ from equity options?
The most important structural difference is settlement currency: most crypto options (particularly on Deribit) are cash-settled in the underlying coin rather than in dollars. This means your P&L in USD terms fluctuates with the coin price even during the option's life — a dynamic called convexity risk that doesn't exist in dollar-settled equity options. Crypto options also use European exercise (exercisable only at expiry), and DVOL is Deribit's implied-volatility index, analogous to the VIX.
