Perpetual futures (perps) are the most traded crypto instrument by volume — surpassing spot markets on most days. They let you bet on price direction with leverage, without owning the underlying asset. Here's how they work.
What Is a Perpetual Future?
A traditional futures contract expires on a set date. A perpetual future never expires — you can hold a position indefinitely as long as you have enough margin and pay the funding rate.
You choose:
- Direction: Long (profit if price rises) or Short (profit if price falls)
- Size: How much notional exposure you want
- Leverage: How much collateral backs the position (e.g., 10x leverage = $1,000 collateral controls $10,000 position)
How the Funding Rate Works
Since perpetual futures don't expire, the mechanism that keeps their price anchored to the spot price is the funding rate — periodic payments between longs and shorts.
- If perp price > spot price: Longs pay shorts (funding is positive)
- If perp price < spot price: Shorts pay longs (funding is negative)
Funding payments happen every 8 hours on most platforms. During bull markets, funding is persistently positive — longs pay to hold their positions. Annualized, this can be 30–100%+ during euphoria, which is an implicit cost of leverage.
This also creates the funding rate arbitrage opportunity: go long spot + short perp = delta neutral, collect funding from longs.
Liquidation Mechanics
When your collateral falls below the maintenance margin requirement, your position is liquidated — the exchange forcibly closes your position to cover losses.
Example: You open a 10x long with $1,000 USDC. You control $10,000 notional. If ETH price drops 9%, your position is worth $9,100 — your loss ($900) approaches your collateral. At ~8–9% down, you're liquidated.
Key rule: Never use maximum available leverage. A 5% move on 20x leverage liquidates you. Most experienced traders use 2–5x on perpetual positions.
Solana Perpetual DEXes in 2026
Drift Protocol — The largest Solana perp DEX by volume. Offers BTC, ETH, SOL, and many altcoin perpetuals. Uses a hybrid AMM + order book model. Supports cross-margin across positions.
Zeta Markets — Options and perpetuals on Solana. European-style options plus perps.
Flash Trade — Jupiter-integrated perpetuals. Simple UX, lower fees on major pairs.
Mango Markets — Recovered from the 2022 exploit, relaunched with improved oracle security. Cross-margin lending and perps.
For reference on CEXes: Binance, OKX, and Bybit handle the majority of crypto perp volume globally. But for on-chain, non-custodial perp trading on Solana, Drift is the standard.
Margin Types
Isolated margin — Each position has its own collateral. If one trade is liquidated, your other positions are unaffected.
Cross margin — All positions share a collateral pool. A profitable short can save a losing long from liquidation. More capital efficient but more complex — one bad position can cascade.
Mark Price vs. Last Price
To prevent unfair liquidations during brief price wicks, reputable exchanges liquidate based on mark price (derived from oracle / index price) not last traded price.
If a candle wicks 5% down and immediately recovers, you shouldn't be liquidated if your position was healthy at the fair value. Always check whether a platform uses mark price liquidation.
The Risk Reality
Leveraged trading is zero-sum (before fees). For every long that profits, a short loses the same amount. The exchange earns fees regardless. Retail traders on average underperform unleveraged spot holding over multi-year periods.
Perps are appropriate for:
- Hedging existing spot positions
- Short-duration directional trades with defined risk
- Funding rate strategies (delta-neutral)
Not appropriate as a primary portfolio strategy for most retail participants.
