PANews reported on March 23 that, according to The Block, Katana, an Ethereum scaling network incubated by Polygon Labs and GSR, has acquired the decentralized exchange IDEX and launched its perpetual contract platform, Katana Perps, based on IDEX's matching engine. IDEX, as an early hybrid "DeFi-CeFi" exchange, will provide order book matching and AMM liquidity infrastructure for Katana Perps. Katana stated that this move is part of its strategy to "own more technology stack and revenue," aiming to complete its infrastructure deployment before regulators open up space for on-chain perpetual contracts. The Katana mainnet was previously launched based on a customized version of the OP Stack and integrated with Polygon AggLayer; initially, Katana Perps received market-making support from GSR, Selini Capital, and Auros.
