Katana, a DeFi blockchain backed by Polygon Labs and GSR, has acquired IDEX and launched a perpetual futures trading platform, entering one of crypto's most competitive markets just as regulatory signals in the US suggest onchain derivatives may be moving closer to legitimacy.
The IDEX acquisition, announced Monday, gives Katana a matching engine and settlement infrastructure with nearly a decade of operating history. IDEX was founded in 2017 by brothers Alex and Philip Wearn and was, at its peak in 2019, the most actively traded decentralized exchange on Ethereum. The exchange raised $2.5 million in seed funding in 2020 to develop its second-generation platform, but has since faded from relevance as Uniswap and newer AMM-based competitors captured the DEX market. Financial terms of the acquisition were not disclosed.
The newly launched Katana Perps platform, seeded with liquidity from GSR, Selini Capital, and Auros, integrates spot trading and leveraged derivatives within a single onchain environment. Katana has also formally appointed Matthew Fisher, who has been running strategy for the project, as CEO.
Onchain perpetuals volume hit $739 billion in January 2026, with decentralized venues now accounting for 10.2% of total crypto perpetuals trading, up from just 2% two years ago, Katana said, citing a Coingecko report. Decentralized perpetual exchanges now process over $1.2 trillion in monthly trading volume, according to Coinbase Institutional's 2026 market outlook. US regulators are also signaling a potential path to permitting crypto perpetual futures domestically, which could substantially expand the addressable market.
The competitive challenge is formidable, however. Hyperliquid commands over 70% of open interest in decentralized perpetuals as of March 2026, operating on a custom Layer 1 blockchain purpose-built for high-speed, gas-free trading. Challengers including Aster and Lighter have collectively eroded Hyperliquid's volume share, but open interest, which is the more meaningful indicator of genuine capital deployment, remains heavily concentrated at the top. Katana enters a market where the infrastructure bar has been set by a platform processing hundreds of billions in monthly volume.
Katana's bet is that integration — combining spot liquidity, routing, and perpetuals in one place — gives it a structural advantage over platforms that handle derivatives in isolation. Whether that proves sufficient differentiation in a market already crowded with well-capitalized competitors remains the central question for the project.
