Katana | What Is Katana Network? — DeFi Layer 2 Explained
Understand Katana Network, an Ethereum Layer 2 for DeFi with productive liquidity, Vault Bridge, core markets, KAT incentives and Agglayer connectivity.
What is Katana Network?
Katana is an Ethereum Layer 2 built specifically around decentralized finance. Instead of spreading liquidity across many unrelated applications, Katana emphasizes a smaller number of core markets and infrastructure components that can reinforce one another. The network supports spot trading, lending and borrowing, perpetual futures, vaults, staking and cross-chain asset flows.
Why Katana exists
DeFi often suffers from fragmented liquidity: assets move across bridges, then sit idle or are split across competing protocols. Katana is designed around the opposite assumption—capital should remain productive and the network should actively support the markets that run on it. That is why the design combines productive bridging, network-owned liquidity and concentrated core applications.
How the economic flywheel works
Assets enter Katana through bridges and may remain productive through Vault Bridge strategies. Users deploy those assets across swaps, lending, borrowing, vaults and perps. Network activity produces economic value through fees and application usage. Part of that value can support liquidity and incentives, which in turn can improve market depth and capital efficiency.
- Bridge capital into Katana.
- Keep underlying assets productive where supported.
- Use corresponding assets across DeFi applications.
- Generate trading, lending and network activity.
- Recycle network economics into liquidity and incentives.
Core markets
Katana concentrates important financial primitives in core apps: Sushi for swaps and liquidity, Morpho for lending/borrowing and curated vaults, and Katana Perps for leveraged perpetual futures. Other applications can compose with these markets rather than recreating fragmented liquidity.
Settlement and interoperability
Katana uses a Geth-based execution stack and connects to Ethereum through Agglayer-related zero-knowledge proof infrastructure. For users this means an EVM-style environment; for developers it means familiar smart-contract patterns combined with Katana-specific bridges, productive assets and network economics.

Frequently Asked Questions
Is Katana an Ethereum Layer 2?
Yes. Katana is an Ethereum Layer 2 designed around DeFi use cases and EVM-compatible applications.
What makes Katana different from a generic L2?
Katana is organized around productive capital, shared core markets, Vault Bridge and network-owned liquidity mechanisms.
Which DeFi markets are core to Katana?
Spot trading, lending and borrowing, vault-based yield and perpetual futures are central markets.
Does Katana use KAT for gas?
No. ETH is the gas token on Katana; KAT is used for staking, voting and incentive coordination.
