Katana Network

Current Katana Network

Katana Network is the current subject of this page. As observed on August 3, 2026, its official network documentation identifies Katana as running on Agglayer’s CDK OP Stack. The same documentation lists chain ID 747474 and ETH as the gas token.

What happened to Katana on Solana?

Katana on Solana was a yield protocol that ran automated options vaults on Solana, and katana.so was its home from late 2021 until 2023. It is a different project from today’s Katana Network, and its app is no longer online.

  • Launch: the team introduced the protocol in a November 15, 2021 post.
  • Product: weekly vaults that sold covered calls and cash-secured puts on more than 11 assets, settled on the Zeta Markets FLEX stack with Pyth price feeds (Pyth interview, July 1, 2022).
  • Peak size: about $43.7 million locked on January 14, 2022, according to DefiLlama.
  • Offline: an Internet Archive capture from November 27, 2023 shows the app returning a “deployment disabled” error. We found no public wind-down notice.
  • Today: DefiLlama still counts about $1.5 million in the protocol’s Solana contracts (checked October 27, 2026).

No public source links the Solana protocol to Katana Network or to this site. Katana.so has no wallet connection and cannot access old vault positions.

What Makes Katana Network Different?

Katana Network is an Ethereum Layer-2 (chain 747474) built around shared liquidity and yield backed by real assets. These are the three things that set it apart from other DeFi chains.

Real Yield, Not Just Emissions

VaultBridge puts bridged assets to work on Ethereum and AUSD adds U.S. Treasury yield, so returns are backed by real assets, not just token printing.

Deep, Unified Liquidity

Liquidity is concentrated across Sushi, Morpho and Yearn instead of scattered across pools, so trades stay deep and yields more stable.

Ethereum Security, ETH Gas

Katana is an Ethereum Layer-2 (chain 747474) that settles to Ethereum and pays gas in ETH, with no new trust assumptions.
