How to Connect Katana to MetaMask

You can connect Katana to MetaMask manually or use ChainList, an EVM network aggregator that instantly adds verified blockchain networks to your wallet. We recommend ChainList because it automatically inputs accurate network details, reducing the risk of errors or phishing. 

Quick Guide to Adding Katana via ChainList:

1. Visit ChainList: Head to the ChainList website and connect your MetaMask wallet.
2. Find Katana: Enter "Katana" in the search bar.
3. Add the Network: Click "Add to MetaMask" next to Katana.
4. Confirm Integration: Approve the prompts in MetaMask to complete the network connection.

Katana Mainnet RPC and Chain ID

If you're manually adding Katana to MetaMask, use these official network details:

• Network Name: Katana
• RPC URL: https://rpc.katana.network/
• Chain ID: 747474
• Currency Symbol: ETH
• Block Explorer URL: https://explorer.katanarpc.com/

Always confirm these details with Katana’s official documentation before connecting, ensuring secure and stable interaction with Katana's DeFi ecosystem.

Katana Testnet (Tatara) RPC and Chain ID

Developers testing applications or users exploring Katana's test environment (Tatara) can manually connect to MetaMask using these settings:

• Network Name: Tatara Network (Katana Testnet)
• Network URL: https://rpc.tatara.katanarpc.com
• Chain ID: 129399
• Currency Symbol: ETH
• Block Explorer URL: https://explorer.tatara.katana.network/

What is Katana?

Katana is an Ethereum-aligned Layer 2 blockchain built on Polygon CDK, purpose-designed for yield-focused DeFi. It leverages Agglayer as its canonical bridge and VaultBridge to deploy bridged assets into Ethereum yield strategies, concentrating liquidity for reliable returns.

Governance involves two multisigs: Katana Admin (3-of-5 for upgrades) and the DeFi Security Council (10-of-13 for security oversight). This structure provides efficient governance, zero-knowledge proof security, and optimized liquidity allocation, boosting yield in core DeFi protocols like Morpho and Sushi.

Final Thoughts

Integrating Katana with MetaMask is straightforward, either manually or through ChainList, offering immediate access to its yield-focused DeFi environment.

Before connecting, always verify network settings via Katana's official docs. For developers, Tatara testnet provides a safe environment to explore functionalities.
