查看食譜Linea builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, mainnet archive with debug and trace, and real-time Streams, all from one dashboard.
Query, subscribe, and stream Linea data with low latency. From a single eth_call to billions of rows of historical logs, you get the right interface for the job.
Six ways to access Linea 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 Linea mainnet and Linea Sepolia testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.
Linea is a zkEVM, EVM equivalent, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode Linea endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL and chain ID 59144.
Point your existing Ethereum codebase at a Quicknode Linea endpoint and deploy. Contracts, libraries, and tooling carry over.
eth_call、eth_getLogs、eth_sendRawTransaction 以及 eth_subscribe 的運作方式，與在Ethereum 上完全相同。
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Linea 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 Linea workload. Clone, customize, and ship.
Full reference for every Linea JSON-RPC method, WebSocket subscription, and the debug and trace namespaces. Code examples for @quicknode/sdk, ethers.js, web3.js, and viem.
Connect a dApp to MetaMask with Ethers.js and send your first Linea transaction.
From your first Linea endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Linea endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated Linea infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.

Land transactions on the same Quicknode account. The Ethereum toolchain you already know works unchanged on chain ID 59144.
Full historical state with no pruning, plus the deep analysis namespaces. Run debug_traceTransaction and trace_block against Linea archive nodes for indexing, simulation, and trading forensics.
Backfill and real-time Linea blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.
具備傳送保證的事件驅動式警示。可訂閱特定地址、事件類型或鏈上條件。
Fetch a block and all of its transaction receipts in a single call with qn_getBlockWithReceipts. Fewer round trips and faster indexing for trackers, explorers, and analytics on Linea.
Batch queries, transaction submission, and contract interactions for HyperEVM and HyperCore historical data.
// Your Ethereum code, pointed at Lineaimport { createPublicClient, http } from "viem";import { linea } from "viem/chains";const 客戶端 = 建立公開客戶端({chain: linea,transport: http(QUICKNODE_LINEA_URL)});const 區塊 = await client.getBlockNumber();// Same methods, same SDK. Just chain ID 59144.
Deploy ERC-20 tokens from a factory contract. Clone the app and ship on Linea.
