Connect to Avalanche mainnet and Fuji 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.
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.
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.
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.
Step-by-step tutorials for building on Avalanche C-Chain, with working code you can run. Deploy contracts, build dApps, query token balances, and stream real-time data.
The Quicknode Multi-Chain Faucet drips Avalanche testnet tokens to your wallet, one drip per network every 12 hours. Connect MetaMask, Coinbase Wallet, Uniswap Wallet, or Phantom and pick your network.
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.
Frequently Asked Questions
Still have unanswered questions? Reach out to support and the Quicknode team can help you find answers.
Land transactions on the same Quicknode account. The Ethereum toolchain you already know works unchanged on chain ID 43114.
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.
Event-driven alerts with guaranteed delivery. Subscribe to specific addresses, event types, or onchain conditions.
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.
Batch queries, transaction submission, and contract interactions for HyperEVM and HyperCore historical data.
eth_call, eth_getLogs, eth_sendRawTransaction, and eth_subscribe all behave exactly as they do on Ethereum.
