Katana acquires IDEX, launches native perps exchange as Polygon-incubated DeFi chain expands

IDEX was the highest-volume DEX on Ethereum back in 2018-2019 before AMMs ate its lunch — acquiring that hybrid order book matching engine is the real play here, not just the brand. Katana is clearly running the Hyperliquid playbook of vertical integration (own the perps stack, don't rent it), but launching into a market where decentralized perp volumes already cleared $739B in January alone means the window for capturing flow as a native chain-level primitive is narrow and brutally competitive. The fact that GSR is both an incubator and a launch market maker creates a tight feedback loop for bootstrapping liquidity, though it also concentrates counterparty risk in ways the "decentralized" branding glosses over — worth watching how the maker diversity evolves post-launch.
