- Katana has acquired Sushi’s exchange deployment and Vault Bridge. Financial terms were not disclosed.
- Together with its March acquisition of IDEX, Katana now owns its core spot trading, perpetual futures and yield infrastructure.
Katana, the DeFi blockchain incubated by Polygon Labs and market maker GSR, has acquired two major applications operating on its network.
The transactions cover Sushi’s decentralized exchange deployment on Katana and Vault Bridge, the yield infrastructure developed by Polygon Labs’ Agglayer team. Financial terms were not disclosed. Sushi originally joined Katana as its core decentralized exchange in May 2025.
The acquisitions follow Katana’s March purchase of decentralized exchange IDEX, whose technology powers Katana Perps. Together, the deals bring the blockchain’s principal spot trading, derivatives and yield products under its ownership.
The move reflects a growing shift in decentralized finance, where blockchain operators are seeking direct ownership of applications rather than relying solely on transaction fees from independent developers.
Why Katana Is Buying Applications Rather Than Hosting Them
Most blockchain networks depend on third-party applications to attract liquidity and users. Those applications generally retain their own protocol revenue, while the underlying blockchain earns transaction-processing fees.
This creates an economic disconnect. A network can facilitate billions of dollars in trading without capturing a proportionate share of the financial activity occurring on it.
Katana is attempting to close that gap through vertical integration.
“This cycle taught every chain the same lesson in public: you can have the most apps in the world and still own nothing when they leave. We decided to flip the script,” Katana CEO Matthew Fisher said in a statement shared with AlexaBlockchain.
“Katana bought its perps engine, its spot venue and its yield layer, brought the perps team in-house, and rewired $KAT to align usage and token value accrual. That’s not a roadmap. It’s done, with buybacks beginning later this year.”
Fisher outlined the strategy in March, when Katana acquired IDEX. At the time, he said the blockchain needed to own more of its technology stack and the revenue attached to it.
Ownership also reduces dependence on external development teams that could redirect resources or liquidity toward competing networks.
However, it introduces additional responsibilities, including infrastructure maintenance, security and operating costs.
What Changes for Traders and Liquidity Providers?
The immediate impact differs across Katana’s three principal products.
Katana Swap: The acquired Sushi deployment is being rebranded as Katana Swap. Its existing smart contracts remain unchanged, meaning users can continue trading through the same underlying exchange infrastructure.
The main change concerns revenue allocation. Protocol fees previously associated with an independently operated exchange will now accrue within Katana’s ecosystem. The announcement does not establish that traders will pay lower transaction fees. Liquidity providers still face market exposure and impermanent-loss risks.
Katana Perps: The IDEX-based perpetual futures platform is already operating in approved jurisdictions. Features include isolated margin and builder codes, which allow third-party applications to integrate its trading infrastructure and earn fees on referred transactions.
Vault Bridge: The technology allows capital backing assets bridged onto Katana to generate yield through Ethereum-based strategies, including Morpho vaults.
Unlike conventional bridges that leave deposited assets idle, Vault Bridge can deploy the underlying collateral into managed strategies. The resulting revenue can support Katana’s ecosystem rather than automatically being distributed to individual depositors.
However, acquiring the technology does not eliminate counterparty or smart-contract exposure. According to Katana’s risk framework, independent curators, including Gauntlet and Steakhouse Financial, manage strategies, while liquidity constraints can delay withdrawals.
Katana Redesigns KAT Tokenomics Around Revenue
Alongside the acquisitions, Katana announced changes to its native KAT token, scheduled to take effect on November 17, 2026.
The existing vKAT emissions-voting system will be discontinued. Users will instead stake KAT through avKAT, simplifying participation and removing the need to vote on liquidity incentives.
The unstaking cooldown will fall from 45 days to seven days, while existing vKAT holders will be able to migrate their positions into avKAT.
More importantly, a portion of revenue from four sources — Katana Swap, Katana Perps, Vault Bridge and sequencer fees — will finance open-market KAT buybacks.
All repurchased tokens will be allocated to avKAT stakers. Purchases will initially follow a fixed schedule before moving toward automated onchain execution.
The company has not disclosed the percentage of revenue allocated to buybacks or its expected purchase volume.
That leaves the financial impact dependent on future trading activity, yield generation and operating economics.
Hyperliquid, Sonic and Optimism Pursue Similar Economics
Katana’s approach comes as several blockchain ecosystems reconsider how they generate revenue and support their native tokens.
Hyperliquid is a perfect example. Its integrated trading infrastructure channels 99% of protocol fees into an Assistance Fund used for HYPE purchases. According to a U.S. securities filing, the fund had acquired and permanently removed 47.1 million HYPE tokens from circulation as of September 8, 2026.
Grayscale estimated that Hyperliquid generated $105 million in revenue during September, illustrating the financial potential of an integrated blockchain and trading platform. However, Hyperliquid’s established trading activity does not guarantee similar results for newer competitors.
Sonic Labs announced its own vertical-integration strategy in February, outlining plans to build or acquire applications across trading, credit, payments and other financial services. Its stated objective is to connect application revenue more directly with demand for the S token.
Optimism has taken a different approach. Its governance approved a 12-month program allocating 50% of incoming Superchain revenue to OP token buybacks, without requiring ownership of the applications operating across participating networks.
Can Ownership Translate Into Sustainable Revenue?
Controlling three core applications creates a more direct relationship between network usage, protocol revenue and tokenholder rewards for Katana.
But it does not guarantee higher token prices, deeper liquidity or sustained trading volumes.
The blockchain must still compete with established decentralized exchanges, derivatives platforms and lending protocols on execution quality, liquidity, security and incentives.
