Katana Swallows IDEX, Builds Proprietary Perpetual Contracts, Betting on This Wave of On-Chain Derivatives

Katana Acquires Veteran DEX Team IDEX

Katana (a DeFi public chain under the Polygon Labs ecosystem) announced the acquisition of the decentralized exchange IDEX, founded in 2017, and launched its perpetual contract platform Katana Perps using IDEX’s technology stack. The announcement was made on March 23, 2026, with Web3 M&A advisor Acquire.Fi handling the entire process. The specific purchase amount was not disclosed.

IDEX has been operating for years with hybrid liquidity and an order-matching engine, offering low latency and a variety of order types. After the merger, the original IDEX team continues under the Katana Perps brand, which is now live at perps.katana.network. Matthew Fisher (formerly with Polygon Labs and Diem Association) is the CEO of Katana, responsible for integrating this project.

Katana aims to unify “spot — lending — issuance — derivatives”: spot trading via Sushi, lending through Morpho, issuance handled by Kensei, and derivatives using the acquired IDEX technology. On governance, vKAT holders can vote to direct incentives toward perpetual markets and share in fees. Fisher explained straightforwardly: “We’re bringing more infrastructure into our tech stack, directly tying trading revenue, and prioritizing services for professional traders.”

Why acquire now:

• Funding and control: Building derivatives infrastructure in-house, capturing chain-level trading fees, and defining the technical route.
• Product synergy: Sharing liquidity and collateral across spot, lending, and perpetual markets on the same chain, improving capital efficiency and possibly narrowing spreads.
• Governance loop: vKAT holders can vote to incentivize perpetual markets, with fee distribution aligned with governance, enabling more flexible resource allocation.

Perpetual Contract Trading Volume Continues to Rise

On-chain perpetual markets remain hot: January 2026 saw a trading volume of $739 billion; by mid-March, the 30-day rolling volume was $671 billion, with daily averages over $18 billion. Price discovery increasingly occurs on 24/7 on-chain venues—recently, during the Iran crude oil incident, traditional exchanges shut down, but Hyperliquid’s oil perpetuals still traded $7.3 billion.

Katana Perps attracted market makers like GSR, Selini Capital, and Auros. Its product highlights include one-click account opening, no gas fees, and millisecond-level matching. The platform emphasizes non-custodial and transparent settlement, targeting institutional and crypto-native traders. Polygon Labs CEO Marc Boiron described this as Katana’s “next phase”—all four modules within the same ecosystem, under their control.

• Acquire.Fi managed the entire acquisition process, marking one of the larger DeFi infrastructure mergers this quarter.
• IDEX’s technology brings on-chain experience close to centralized exchanges: chart trading, stop-loss orders, APIs, etc.
• This move aligns with Katana’s strategy to connect spot and derivatives liquidity, potentially improving spreads and capital efficiency.
• How IDEX’s original token will be handled remains unclear; official updates are awaited.
• Katana Perps launched Season 1 reward program to attract trading and liquidity, but US users are ineligible.

In 2019, IDEX was once the largest on-chain DEX on Ethereum. This acquisition integrates its derivatives capabilities into Katana’s tech stack, with perpetual revenue and spot/lending fees fueling the ecosystem flywheel. By the way, this has nothing to do with the similarly named Katana DEX on Ronin Chain; all developments are within the Polygon ecosystem.

My take: For on-chain derivatives, it’s still early days. Professional market makers and active traders benefit most immediately, while builders and funds aiming to position at the infrastructure layer also have advantages. Conservative long-term holders might want to wait and see; retail investors may not find the timing ideal right now.
