About katana
Katana is a Layer-2 blockchain network identified by chain ID 747474, developed by Polygon Labs and GSR. Launched in May 2025, Katana is designed specifically for decentralized finance (DeFi) applications, aiming to unify liquidity and deliver sustainable yields.
The network utilizes Ether (ETH) as its native currency, with 18 decimal places. Katana operates on Agglayer's CDK OP Stack, integrating with Ethereum and other Layer-2 solutions through Agglayer's Unified Bridge.
Katana's ecosystem focuses on core DeFi applications, including a spot decentralized exchange (DEX) and a lending protocol, to concentrate liquidity and enhance yield opportunities. The network also features mechanisms like VaultBridge and Chain-Owned Liquidity (CoL) to support deep liquidity and high yield.
Users can interact with the Katana network through various RPC endpoints. Block explorers provide transparency and monitoring capabilities for network activities.
