了解更多Katana builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, full archive with debug, and real-time Streams, all from one dashboard.
Six ways to access Katana data, from a single eth_call to billions of rows of queryable history. Pick the interface, ship faster.
Standard JSON-RPC over HTTPS and WSS on Katana mainnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.
Katana is a DeFi-focused Ethereum layer 2, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode Katana endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL.
Point your existing Ethereum codebase at a Quicknode Katana endpoint and deploy. Contracts, libraries, and tooling carry over.
eth_call、eth_getLogs、eth_sendRawTransaction 和 eth_subscribe 的行为与在Ethereum 上的行为完全一致。
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Katana RPC URL with the details on the right. Save, and MetaMask routes through your private Quicknode endpoint instead of a rate-limited public RPC.
Docs, guides, and runnable sample apps for every Katana workload. Clone, customize, and ship.
Full reference for every Katana JSON-RPC method, WebSocket subscription, and the debug and trace namespaces. Code examples for @quicknode/sdk, ethers.js, web3.js, and viem.
Indexes token transfers on an EVM chain using Quicknode Streams and delivers them to your own datastore and API. Works unchanged on Katana.
From your first Katana endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Katana endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated Katana infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.

Query, subscribe, and stream Katana data with low latency. From a single eth_call to billions of rows of historical logs, you get the right interface for the job.
The Ethereum toolchain you already know works unchanged on Katana. Deploy contracts, manage endpoints, and ship from one Quicknode account.
Full historical Katana state with no pruning. Run debug_traceTransaction and debug_traceBlockByNumber against archive nodes for indexing and simulation.
Backfill and real-time Katana blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.
具有交付保证、重试功能和内置重组处理机制的事件驱动型警报。订阅特定地址、合约事件或链上条件，并实时做出响应。
Read rollup sync status and L2 output roots with optimism_syncStatus and optimism_outputAtBlock. This is the data bridges and withdrawal-proving flows use to verify Katana state against Ethereum L1.
Subscribe to new Katana blocks and logs over a persistent WSS connection with eth_subscribe. Push updates the moment they land, with no polling.

Katana is a DeFi-focused Ethereum layer 2.
Runnable sample apps and starter kits across Quicknode-supported chains, including Katana. Clone one and ship.
"Relay routes cross-chain intents across dozens of networks, so every new chain we add has to be rock-solid from the first block. Quicknode's HyperEVM support gave us the performance and uptime we need to quote and settle swaps in real time, without babysitting infrastructure."Julien Genestoux, VP of Engineering @ Uneven Labs (Relay)
