Synthetix is set to launch the first perpetual decentralized exchange on Ethereum mainnet in Q4 2025, kicking off with a $1 million trading competition. Summary Synthetix to launch first perpetual DEX on Ethereum mainnet in Q4 2025. Traders can use sUSDe, wstETH, and cbBTC as multi-collateral margin. Launch begins with a $1M trading competition starting in October.

This enables users to earn funding or staking yields, keep exposure to ETH or BTC, and avoid triggering taxable events when opening perp positions. Synthetix expects that this design will increase the efficiency and profitability of arbitrage strategies such as basis trading. For example, traders can deposit wstETH, short ETH perps in equal size, and benefit from staking rewards and positive funding payments. By enabling these setups directly on Ethereum, Synthetix removes the need for bridging and expands composability with decentralized finance protocols like Aave.
