Frequently Asked Questions

What is Optimism?

Optimism is the earliest production optimistic rollup; its OP-Stack now powers the “Superchain” of cooperating L2s and funds public-goods development through retroactive airdrops.

How to get Optimism RPC endpoint?

Sign up for a free Chainstack account and open your project dashboard. In the dashboard, choose Add node, select Optimism, and provision either a dedicated node or an elastic cluster. After the node syncs, open Access & credentials and grab the RPC URL for immediate integration.

How to run an Optimism node?

Deploy a Global Node via Chainstack to ride the Optimism Superchain in under five minutes. Pick a Dedicated Node for guaranteed I/O and fine-grained retention policies. The DIY path? Compile op-node, fetch Geth, juggle data availability service configs, and hope migrations don’t break overnight.

What is Optimism RPC API?

Optimism exposes an Ethereum-compatible JSON-RPC plus op_getBlock that returns L2-specific metadata. Clients send raw transactions as usual, while the OP Node handles derivation and output roots. WebSocket subscriptions include both standard logs and Optimism system events.

How much does it cost to run a Optimism RPC?

A self-hosted OP node plus Geth backend can cost anywhere from US $120 to US $300 / month, depending on region, SSD size, and bandwidth. Heavy simulation or MEV use cases raise those numbers quickly. The lowest-stress, lowest-cost option is to point to an Optimism RPC delivered by a provider such as Chainstack.

Is Optimism RPC free?

Optimism supplies open RPC links that cost nothing, yet they often throttle heavy workloads. Chainstack’s entry tier grants 3 million stable Optimism calls for free, eliminating that headache.

How to setup a Optimism RPC?

Fetch the Optimism endpoint in Chainstack, then insert it in the wallet’s “RPC URL” box or change the provider string in your dApp code to talk to Optimism.

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.
