Build better with Optimism nodes

Run high-performing Optimism RPC nodes and APIs in minutes on a platform built for scale.

Reliable Optimism Mainnet, Sepolia and Goerli Testnet infrastructure

Chainstack makes sure you get access to robust and scalable infrastructure, ready for your Optimism journey, in a matter of minutes.

We take away the burden of managing it so that you can instantly focus on building and exploring data on Optimism.

Get started

Start fast with Global Optimism RPC Nodes

Global Optimism RPC Nodes provide personal, geographically diverse, and protected API endpoints you can immediately start using to interact with the Optimism network, starting at $0 per month.

Turbocharged sync

With Chainstack’s patented Bolt technology, you get fully synced dedicated Optimism RPC nodes in almost no time at all.

By using up-to-date snapshots of the ledger, Chainstack spins up dedicated Optimism RPC nodes with the latest state—so you get a node ready same day rather than having to wait long sync times while spinning it from genesis block.

Notes for Optimism API

When communicating with an Optimism RPC node, the Optimism client implements a JSON-RPC specification, a communication protocol allowing one to make remote calls and execute them as if they were made locally.
The Optimism API allows developers to communicate with the Optimism blockchain to build applications. The best way to use the Optimism API is to use a web3 library such as ethers.js if using Javascript or web3.py if using Python.
