了解更多Connect to Avalanche mainnet and every active testnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete Avalanche data stack, managed from a single Quicknode dashboard.
已通過 SOC 2 Type II 認證 · ISO 27001
Avalanche builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, full archive with debug and trace, and real-time Streams, all from one dashboard.
Query, subscribe, and stream Avalanche 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 Avalanche 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 Avalanche C-Chain and Fuji testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.
Full historical state with no pruning, plus the deep analysis namespaces. Run debug_traceTransaction and trace_block against Avalanche archive nodes for indexing, simulation, and trading forensics.
Backfill and real-time Avalanche 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、重試機制及內建重組處理功能的事件驅動式警示。訂閱特定地址、合約事件或鏈上條件，並即時做出反應。
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 Avalanche.
Subscribe to new blocks, logs, and pending transactions over a persistent WSS connection with eth_subscribe. Push updates the moment they land, with no polling.
The Avalanche C-Chain is EVM compatible, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode Avalanche endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL and chain ID 43114.
Point your existing Ethereum codebase at a Quicknode Avalanche endpoint and deploy. Contracts, libraries, and tooling carry over.
eth_call, eth_getLogs, eth_sendRawTransaction, and eth_subscribe all behave exactly as they do on Ethereum.
// Your Ethereum code, pointed at Avalancheimport { createPublicClient, http } from "viem";import { avalanche } from "viem/chains";const client = createPublicClient({chain: avalanche,transport: http(QUICKNODE_AVALANCHE_URL)});const block = await client.getBlockNumber();// Same methods, same SDK. Just chain ID 43114.
Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Avalanche 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 Avalanche workload. Clone, customize, and ship.
Full reference for every Avalanche JSON-RPC method, WebSocket subscription, and the debug and trace namespaces. Code examples for @quicknode/sdk, ethers.js, web3.js, and viem.
Spin up a dApp on the Avalanche Fuji testnet with Quicknode, from wallet connection to onchain calls.
Explore any wallet's balances and history. Clone the app and point it at Avalanche.
From your first Avalanche endpoint to mission-critical production workloads, Quicknode scales with you. Get started in minutes.
Spin up your Avalanche endpoint and ship. The free tier covers prototyping and small production loads, no credit card required.
Dedicated Avalanche infrastructure, contractual SLAs, priority support, and procurement-ready terms for wallets, exchanges, trading firms, and high-volume protocols.
