Mainnet, Testnet, Archive, and
Streams in One Dashboard.

OP Mainnet 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.

Data Access for Every OP Mainnet Workload

Query, subscribe, and stream OP Mainnet data with low latency. From a single eth_call to billions of rows of historical logs, you get the right interface for the job.

JSON-RPC over HTTPS and WSS on OP Mainnet and OP Sepolia Testnet
Full archive nodes with debug_traceTransaction and trace_block
Streams for backfill and real-time OP Mainnet blocks, logs, and traces
Webhooks for push notifications on addresses and events
Single Flight RPC to fetch a block and all its receipts in one call
// Build & Ship

EVM Tooling and Reliable Sends

Land transactions on the same Quicknode account. The Ethereum toolchain you already know works unchanged on chain ID 10.

Smart Transactions and reliable broadcasting to land transactions during congestion
Token authentication, rate-limiting, JWT, and whitelisting on every endpoint
ethers.js, web3.js, viem, and @quicknode/sdk supported out of the box
Archive access with debug and trace for indexing and simulation

Every OP Mainnet Data Pattern.

Six ways to access OP Mainnet data, from a single eth_call to billions of rows of queryable history. Pick the interface, ship faster.

OP Mainnet JSON-RPC

Standard JSON-RPC over HTTPS and WSS on OP Mainnet and OP Sepolia Testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.

Explore Core RPC API

Archive, Debug & Trace

Full historical state with no pruning, plus the deep analysis namespaces. Run debug_traceTransaction and trace_block against OP Mainnet archive nodes for indexing, simulation, and trading forensics.

Explore Archive Access

Streams

Backfill and real-time OP Mainnet blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.

Explore Streams

Webhooks

Event-driven alerts with guaranteed delivery. Subscribe to specific addresses, event types, or onchain conditions.

Explore Webhooks

Single Flight RPC

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 OP Mainnet.

Explore Single Flight RPC

JSON-RPC

Batch queries, transaction submission, and contract interactions for HyperEVM and HyperCore historical data.

Quicknode by name.
Quick by numbers.

Trailing 24-hour P95 OP Mainnet RPC response time, the slowest 5% of requests, the tail your users actually feel. Averaged across five global regions and measured against the most-cited providers in the category. Lower and flatter is better.

ProviderP95 OP Mainnet RPC Latency
Quicknode49 ms
Infura262 ms
Alchemy280 ms
Ankr364 ms

P95 (95th-percentile) JSON-RPC latency over the trailing 24 hours, averaged across five global regions, identical conditions across providers. The full benchmark defaults to a longer window, so its figures will differ.

// Built for EVM Developers

Your Ethereum app runs on OP Mainnet.

OP Mainnet is EVM equivalent, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode OP Mainnet endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL and chain ID 10.

No rewrites

Point your existing Ethereum codebase at a Quicknode OP Mainnet endpoint and deploy. Contracts, libraries, and tooling carry over.

Same JSON-RPC methods

eth_call, eth_getLogs, eth_sendRawTransaction, and eth_subscribe all behave exactly as they do on Ethereum.

// Same methods, same SDK. Just chain ID 10.
// Add OP Mainnet to MetaMask

Connect MetaMask to OP Mainnet in seconds.

Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode OP Mainnet RPC URL with the details on the right. Save, and MetaMask routes through your private Quicknode endpoint instead of a rate-limited public RPC.
