- You keep your keys, but contract risk stays with you.

Traders use perp DEXs to bet on price moves or hedge a spot position.
How Does a Perpetual DEX Work?
A perpetual DEX runs as smart contracts on a blockchain. You connect your wallet and keep your keys, so the platform does not hold your funds.
- Trades settle through smart contracts, not a company account.
- You connect your wallet and keep control of your keys.
- A funding rate is a periodic payment between long and short traders that pulls the contract price toward spot.
How Do People Trade on One?
You deposit collateral, pick a market, and choose a position size. You can add leverage to increase the position relative to your collateral.
What Are the Main Risks and Limits?
Leverage magnifies gains and losses. If the market moves against you, the contract can be liquidated, and you may lose the collateral backing that trade. US access is often restricted.
How Is It Different From a Spot DEX?
A spot DEX trades the actual coin, and the coin moves to your wallet. A perpetual DEX does not deliver the coin; you trade a contract that tracks the price.
