Katana RPC Endpoint

Fast, flat-rate Katana RPC node provider — free tier, no KYC, HTTP & WebSocket.

Katana is a DeFi-focused Ethereum Layer 2 that concentrates liquidity and routes protocol revenue back into yield for its users. It launched its public mainnet in 2025 with backing from Polygon Labs and GSR. SwiftNodes provides RPC access to Katana.

About Katana

Katana (chain ID 747474) is an EVM Layer 2 that uses ETH as its gas token. Its public mainnet went live in 2025 with a design centered on deep, productive liquidity and crosschain asset support.

Katana has a separate network token, KAT, earned through liquidity programs rather than used for gas. As a DeFi-native chain it is targeted at lending, AMMs, and yield strategies. Standard EVM tooling such as Foundry, Hardhat, viem, and ethers.js applies.

Common Use Cases on Katana

• AMM and DEX trading
• Lending and borrowing
• Yield strategies
• Stablecoin liquidity
• Crosschain asset deployment

Katana Ecosystem
