Polygon’s Katana Strikes: $240M Floods Into DeFi in Record-Breaking Launch
Polygon just unsheathed Katana—and DeFi whales are already throwing money at it like Wall Street bonuses.
The bleeding-edge scaling solution racked up $240 million in deposits within hours of launch, proving Ethereum's layer-2 wars are far from over. Forget 'if you build it, they will come'—this is 'if you slash gas fees by 90%, they'll dump bags faster than a Celsius withdrawal queue.'
Katana's secret sauce? A hybrid rollup architecture that cuts settlement times to sub-seconds while keeping costs lower than a TradFi broker's integrity. Early adopters include yield farmers, arbitrage bots, and that one degenerate who probably leveraged their NFT portfolio to ape in.
Meanwhile in Manhattan: hedge funds are still trying to explain to limited partners why they missed the boat—again.

- Polygon officially launched Katana, a new Layer 2 blockchain focused on enhancing DeFi experiences, reaching over $240 million in deposits within three weeks.
- Katana integrates major DeFi projects like Morpho, Sushi, and Vertex, plus supports innovative tokens such as Agora’s AUSD and EtherFi’s weETH.
- Katana will airdrop 1.5 billion KAT tokens (~15% of total supply) to POL holders, rewarding community participation and long-term network growth.
Polygon has officially released Katana, its new Layer 2 blockchain for maximizing decentralized finance (DeFi) experiences, announced Polygon Foundation CEO Sandeep Nailwal in an announcement released Monday. The significant milestone initiates what Nailwal calls a “new era for DeFi,” capable of revolutionizing how people extract yield on their digital assets through creative solutions such as AggLayer’s Vault Bridge.
Ecosystem Announcement 🚢
Katana is live on mainnet. Katana will bring in a new era for DeFi that will change how users earn yield on their assets, with Agglayer’s Vault Bridge.
In just three weeks, Katana already has over $240M in productive pre-deposited assets.
The Agglayer… https://t.co/9sQTtfoxUY
Katana, a product that was created in partnership with Polygon Labs and leading crypto market maker GSR under their incubation program, was developed with a special iteration of OP Stack called cdk-opgeth. Through this customized setup, Katana can be directly integrated into AggLayer’s Vault Bridge, an innovative cross-chain interoperable protocol.
Through this integration, bridged tokens can actively generate revenue for their owners and give them new revenue-generating avenues for their holdings. The announcement aims to address one of DeFi’s major issues: fragmentation.
By collecting together liquidity from diverse protocols in a single protocol stack, Katana hopes to become a self-sustaining engine for liquidity that will sustain DeFi development over time. Through this centralized approach to liquidity, parties in diverse segments of the DeFi space will be able to reap higher returns and higher efficiency.
Polygon’s Katana Integrates Key DeFi Projects
Before the public mainnet release, Katana went through a private mainnet window starting from late May. As a part of that, various major DeFi projects such as borrowing protocol Morpho, decentralized exchange Sushi, and perpetual swaps solution Vertex connected their networks.
Katana is here ⚔️
A DeFi-first chain with high yield and DEEP liquidity; deep enough to provide liquidity for the entire Agglayer ecosystem.@Katana is a paradigm shift—aligning apps, users, and chain revenue from day one.

Other than that, Katana also began to support various new innovative tokens, including Agora’s AUSD stablecoin, Lombard’s liquid-staked wrapped LBTC, and EtherFi’s yield-bearing weETH, expanding its network with diverse DeFi options.
As it soft-launched, Katana enabled prototype users to pre-deposit coins and be rewarded with the native KAT token. Interestingly, in just three weeks, the protocol mustered over $240 million in “productive” deposited funds, showing strong market interest and trust.
For the foreseeable future, Katana shall be an integral liquidity center in the AggLayer network that enables interoperable blockchains to tap into massive capital pools. Access to deep liquidity of this nature shall generate massive fee revenue for stakers of the POL token, yet another incentive for participation in the Polygon network.
As a token of appreciation for the community, Katana will airdrop around 15% of its overall 10 billion token offering, about 1.5 billion KAT tokens, to holders of POL so that they will have extra value and ownership in Katana’s potential success in the future.
Polygon’s launch constitutes a significant step in restructuring the DeFi landscape through offering scalable, interoperable, and yield-optimized solutions that can become industry standards for decentralized finance in the NEAR future.
