Decentralized exchanges for perpetual futures — or perp-DEXes — have become one of the fastest-growing segments of DeFi in 2025.
In September alone, monthly trading volume hit $1.05 trillion, marking an all-time high.
Behind this surge are new platforms redefining what on-chain derivatives can be.

What Are Perp-DEXes?

A perp-DEX allows traders to open leveraged long or short positions on crypto assets without expiration dates — directly on-chain.
Unlike centralized exchanges, all trading, collateral, and liquidations are handled by smart contracts.
This gives users full custody of funds, but also exposes them to protocol and market risks.

Each platform builds its own approach to solving the same challenge: how to make leverage trading fast, cheap, and transparent.

Aster — The New Market Leader

Aster (Arbitrum) exploded after its token launch in September 2025, growing +1320% and processing nearly $500B in monthly volume.
Its success comes from a mix of low fees (0.01%–0.03%), deep liquidity through incentive pools, and high-speed matching that rivals CEX-level execution.
With $2.18B TVL, Aster now dominates almost half of the market and challenges Hyperliquid’s long-held lead.

Lighter — A Rapidly Rising L2 Competitor

Lighter (Ethereum L2) is still in private beta, but already sees daily volumes near $10B.
It focuses on performance and user experience, integrating one-click margin trading and cross-collateral accounts.
If its beta continues scaling smoothly, Lighter could become the first true Ethereum-native alternative to Arbitrum’s DEX dominance.

Hyperliquid — The Pioneer on Its Own Chain

Once the undisputed leader, Hyperliquid built its own L1 for ultra-fast execution and sub-second finality.
With 0.01% maker / 0.035% taker fees, it attracted professional traders and institutions.
But after months of controlling 73% of the market, its share is now shrinking as new players enter with better incentives and more transparent token models.

Pacifica and the Solana Ecosystem

On Solana, Pacifica has overtaken Jupiter Perp to become the largest perp DEX in the ecosystem.
It combines Solana’s high throughput with user-friendly design and a flexible liquidity model.
Fast confirmation and composability with Solana’s DeFi stack make it appealing for both retail and algorithmic traders.

Apex and dYdX — The Cross-Chain Players

Apex Protocol, backed by Bybit, bridges centralized and decentralized derivatives by sharing liquidity across both ecosystems.
Its multi-chain setup allows professional traders to hedge or arbitrage positions directly from on-chain vaults.

Meanwhile, dYdX v4 continues evolving on Cosmos, offering up to 20x leverage and full on-chain governance.
Though its volumes are lower than Aster’s or Hyperliquid’s, dYdX remains a reference point for transparency and execution quality.

SunPerp — Tron’s First Perpetual DEX

While smaller in scale, SunPerp deserves mention as the first perp-DEX on Tron.
Its $30M TVL marks the beginning of derivatives expansion on one of the most active retail blockchains.
If liquidity deepens, Tron’s vast user base could make it a regional leader in Asia.

Why It Matters

Perp-DEXes are becoming the core of on-chain finance — providing exposure, hedging, and speculation tools without intermediaries.
As their execution speeds and liquidity improve, the gap with centralized exchanges keeps narrowing.

But this progress comes with risks: high leverage amplifies losses, and smart contract bugs or oracle failures can wipe positions instantly.
Users should start small, understand margin mechanics, and never trade more than they can afford to lose.
