What Is Katana Network? Chain, KAT Token & RPC Guide
Katana Network is a DeFi-focused Ethereum Layer-2 blockchain, incubated by Polygon Labs and GSR, that uses ETH for gas and runs on chain ID 747474. It is built to concentrate liquidity and pass real, sustainable yield back to users rather than spread incentives thinly across many chains. If you searched “katana solana,” note the key fact up front: Katana Network is not a Solana project — it is an Ethereum L2, and its native gas token is ETH, not SOL.
Key takeaways
- Katana Network is an Ethereum Layer-2 for DeFi, incubated by Polygon Labs and GSR and operated by the nonprofit Katana Foundation.
- Chain ID is 747474 (hex 0xb67d2); gas is paid in ETH; the public RPC is https://rpc.katana.network/.
- The native token is KAT, with a total supply of 10 billion and 1 billion set aside for launch incentives.
- Core building blocks are VaultBridge (real yield from Ethereum), AUSD (a Treasury-backed stablecoin), and Chain-Owned Liquidity funded by sequencer fees.
- Katana is not on Solana and is a separate project from the older Katana DEX on the Ronin chain.
What is Katana Network?
Katana Network is an EVM-compatible Layer-2 blockchain designed around a single idea: solve liquidity fragmentation in DeFi. Instead of incentives chasing mercenary capital across dozens of chains, Katana concentrates liquidity in a smaller set of core applications and routes outside yield back into them. It was incubated by Polygon Labs and trading firm GSR, and it is operated by the Katana Foundation, a nonprofit.
Because Katana is EVM-compatible, the wallets and tooling you already use on Ethereum work here. You bridge assets in, pay transaction fees in ETH, and interact with familiar protocols — Sushi for trading, Morpho for lending and borrowing, and Yearn for vaults — alongside Katana-native features.
Katana Network chain settings and RPC
To add Katana Network to a wallet such as MetaMask, use these official network details:
| Setting | Value |
|---|---|
| Network name | Katana |
| Chain ID | 747474 (0xb67d2) |
| Gas / currency symbol | ETH |
| RPC URL | https://rpc.katana.network/ |
| Block explorer | https://katanascan.com |
| Type | Ethereum Layer-2 (EVM) |
Always confirm these values against the official Katana documentation before connecting a wallet. Scam sites copy chain names and prompt approvals on fake RPCs.
The KAT token explained
KAT is the native token of the Katana ecosystem. Total supply is 10 billion KAT. At mainnet, 1 billion KAT was allocated as liquidity-mining incentives to bootstrap the chain — split across Sushi (400 million KAT), Morpho (250 million KAT), and up to 350 million KAT reserved for future perpetual DEX, launchpad, and yield-tokenization apps. Before mainnet, the network secured more than $240 million in pre-deposits, with 67 million-plus unclaimed KAT redistributed to pre-deposit participants.
KAT is not just an emissions token. Holders can lock it to take part in governance and share in protocol revenue through Katana’s staking system. For the full mechanics, see our Katana staking guide covering vKAT and avKAT.
How Katana generates real yield
Three mechanisms separate Katana from a standard incentive farm:
- VaultBridge — bridged assets such as USDC, WETH, WBTC, and USDT are deployed into yield-bearing strategies on Ethereum and returned as vbTokens (for example vbETH and vbUSDC). That outside yield flows back to Katana users as a sustainable base return. Read our explainer on Katana VaultBridge and AUSD yield.
- AUSD — Katana’s native stablecoin, issued by Agora, is backed by offchain U.S. Treasuries with reserves custodied by State Street and managed by VanEck. It brings Treasury yield onchain to support lending markets and liquidity pools.
- Chain-Owned Liquidity (CoL) — net sequencer fees are reinvested into protocol-owned liquidity instead of being extracted, deepening pools over time.
Is Katana Network on Solana?
No. Katana Network is an Ethereum Layer-2 on chain ID 747474 and uses ETH for gas. The “katana solana” confusion is common because both are high-throughput DeFi ecosystems, but they are different chains with different tokens. If a site claims to be “Katana on Solana” and asks you to connect a Solana wallet, treat it as a red flag. Our deeper breakdown is in Is Katana on Solana? safety checks for KAT users, and the DeFi side is covered in Katana DeFi explained.
Frequently asked questions
What chain is Katana Network on?
Katana is its own Ethereum Layer-2 with chain ID 747474 (hex 0xb67d2). It is EVM-compatible and uses ETH as its gas token.
Who built Katana Network?
Katana was incubated by Polygon Labs and GSR and is operated by the Katana Foundation, a nonprofit. Core DeFi partners include Sushi, Morpho, and Yearn.
What is the KAT token used for?
KAT powers incentives, governance, and revenue sharing. Holders lock KAT to receive vKAT or avKAT, which direct emissions to liquidity pools and earn a share of trading fees and vault revenue.
Is Katana Network the same as Katana DEX on Ronin?
No. The older Katana DEX is an automated market maker on the Ronin chain. Katana Network is a separate Ethereum Layer-2. They share a name but are different products.
