Katana, a DeFi-focused Ethereum scaling layer incubated by Polygon Labs and GSR, announced on Monday the acquisition of IDEX, a decentralized exchange launched in 2017. Katana will use IDEX as the backbone for its new Katana Perps platform. Terms of the deal were not disclosed. IDEX combines a traditional centralized-style order book with an automated market maker.

Acquisition Overview
Katana acquired IDEX to own more of its technology stack and associated revenues. Katana CEO Matthew Fisher stated: “When I became CEO, I decided that Katana needed to own more of its stack and the revenues attached to it. IDEX and Katana Perps are the first moves in that direction.” Fisher noted the infrastructure supports always-on markets for real-time price discovery as regulations evolve for onchain perpetuals. The announcement occurred on Monday, as broader industry consolidation trends continue to emerge. Recent developments such as Impossible Finance Acquires Rarible highlight a growing push toward vertically integrated Web3 ecosystems.

Katana Perps provides a perpetual futures platform that unifies spot and derivatives trading in one onchain environment.
