Perpetual futures are a way to trade on the price of an asset without buying it.
Unlike traditional futures, perps never expire—they use a recurring payment called the funding rate to stay aligned with the market price.
Leverage lets traders control larger positions with less capital, but amplifies losses just as much as gains.
Perps carry a high risk of total collateral loss and are not suitable for all participants.
Perpetual futures—usually just called perps—are a way to trade on the price of crypto or digital assets without actually buying it. If a trader thinks ETH will rise, they can open a position that profits when it does. If they think it will fall, they can open a position that profits from the decline. No token changes hands either way.
Two features set perps apart from simply buying and holding. First, they let traders borrow to trade bigger, a concept called leverage, which magnifies both profits and losses. Second, perps never expire. A position stays open as long as there's enough collateral behind it.
This guide explains how all of that works: what perps are, how a trade is structured, what the costs and risks look like, and what happens when a position goes wrong. For a foundational overview, see key perpetual futures concepts.
Disclaimer: This guide is for educational purposes only. It is not financial advice, not a solicitation, and not for UK audiences. Perpetual futures carry a high risk of loss, including the total loss of deposited collateral, and are not suitable for all users.
Why perpetual futures exist
Crypto markets run 24/7. Traditional futures were designed for markets that close overnight and on weekends. They have fixed expiration dates that force traders to close or roll their positions on a schedule. That creates costs, timing pressure, and friction.
Perpetual futures remove that friction. A perp never expires, so a position can stay open indefinitely. The trade-off is a small recurring cost called the funding rate—a payment exchanged between traders on opposite sides of the market, typically every eight hours, that keeps the perp price aligned with the actual market price of the asset.
The result is an instrument that works like a futures contract but trades more like a spot position: continuous, no rollovers, no forced settlement dates.
How a perpetual futures trade works
A perp trade comes down to three decisions:
Which direction. A trader who expects the price to rise opens what's called a long position. A trader who expects it to fall opens a short position.
How big, and how much leverage. The trader deposits collateral—called margin—which are the funds used to open the position. Leverage determines how much exposure that collateral controls. At 5x leverage, $1,000 in margin controls a $5,000 position. That means both profits and losses are five times larger than they would be without leverage. For a detailed breakdown of how leverage, margin requirements, and tiered margin systems work, see leverage and margin in perpetual futures trading.
How to manage risk. Two order types help control outcomes. A stop-loss automatically closes the position if the price moves too far in the wrong direction, limiting losses. A take-profit automatically closes it when the price hits a target, locking in gains. Without these, a leveraged position can lose value faster than expected during volatile markets. On MetaMask Perps, both can be set when opening a position, and the platform is designed so that losses are limited to the deposited collateral under normal market conditions—though extreme scenarios such as auto-deleveraging may affect outcomes.
Once open, the position is subject to funding rate payments at regular intervals. When the perp price is above the market price, traders on the long side pay traders on the short side. When it's below, the reverse happens. This keeps the perp price from drifting away from reality. For more on how funding frequency and rate calculations affect trading costs, see perpetual futures funding frequency and strategies.
How perps differ from spot trading
Spot trading means buying and owning the actual asset. A spot ETH purchase puts real ETH in a wallet. There's no leverage, no risk of forced closure, and no ongoing funding cost. The position lasts as long as the holder wants. Spot is typically used for long-term holding and participation in onchain activities like staking.
Perps work differently. There's no ownership, just a contract that tracks the price. Leverage is available, which means larger exposure from less capital, but also larger losses. And positions carry an ongoing cost (the funding rate) that doesn't exist in spot.
Here's a hypothetical scenario showing what happens to a long position as the price moves.
A trader deposits $100 as collateral and opens a long ETH position at 5x leverage. That $100 controls $500 of exposure, with ETH priced at $2,000.
ETH rises 10% to $2,200: The position gains $50. The trader's $100 is now worth $150—a 50% return on the deposited collateral.
ETH falls 10% to $1,800: The position loses $50. The trader's $100 drops to $50.
ETH falls 20% to $1,600: The position loses $100—everything the trader put in. At or before this point, the position is automatically closed. This is called
The pattern: a 10% move in the asset becomes a 50% move in the collateral at 5x leverage. That's the core dynamic. Leverage doesn't change the market—it changes how much of the trader's money is at stake for any given move.
Understanding the risks
Liquidation. If losses eat through the deposited collateral past a minimum threshold (called the maintenance margin), the platform forcibly closes the position. Higher leverage means a smaller price move triggers this. At 50x leverage, roughly a 2% adverse move is enough. Liquidation is calculated against the mark price—an aggregated reference price designed to resist manipulation. For a full walkthrough of how liquidation works, including cascading liquidations and auto-deleveraging, see perpetual futures liquidation mechanics.

Exact thresholds depend on the platform's maintenance margin rate and margin mode.
Funding costs. Holding a position over hours, days, or weeks means accumulating funding payments. During periods when many traders are positioned in the same direction, funding rates can become a meaningful cost that's easy to underestimate. For more on how funding frequency shapes costs, see perpetual futures funding frequency and strategies.
Volatility. Crypto markets move fast. During sharp drops, liquidation of heavily leveraged positions can accelerate the move further—one forced closure triggers the next in a cascade. This can catch even well-collateralized positions.
Margin mode. Most platforms offer two ways to allocate collateral. Isolated margin means only the collateral assigned to a specific trade is at risk—if that trade is liquidated, the rest of the account is untouched. Cross margin means the entire account balance backs all open positions, which provides more cushion but also means one bad trade can drain everything. For a full comparison, see cross vs isolated margin in perpetual futures.
Counterparty and platform risk. The exchange or protocol processing the trade carries its own risks—smart contract vulnerabilities in decentralized protocols, or the risk of a centralized exchange freezing withdrawals.

Frequently asked questions about perps for beginners
Buying crypto (spot trading) means owning the actual asset—no leverage, no liquidation risk, no funding cost. Perps let traders speculate on price direction with leverage and the ability to profit from falling prices, but without ever holding the token. The trade-off is ongoing funding costs and the risk of losing all deposited collateral through liquidation.
The platform's liquidation engine automatically closes the position when the collateral falls below the maintenance threshold. In isolated margin mode, losses are limited to the collateral assigned to that specific position—the rest of the account is unaffected.
On platforms using isolated margin—including MetaMask Perps—losses on a liquidated position are limited to the deposited collateral under normal market conditions. In extreme scenarios, a separate mechanism called auto-deleveraging (ADL) may affect profitable positions on the opposite side, but the loss on the liquidated position itself does not exceed the posted collateral.
Minimums vary by platform and asset. There's no universal floor—some platforms allow positions with a few dollars of collateral at high leverage, though smaller positions carry proportionally higher liquidation risk relative to fees and funding costs.
Yes, as long as there's enough collateral above the maintenance threshold and funding payments are covered at each interval. There's no expiry date forcing settlement or closure.
