Build better with opBNB nodes

Run high-performing opBNB nodes in minutes on a platform built for scale.

Reliable opBNB Mainnet infrastructure

Chainstack makes sure you get access to robust and scalable infrastructure, ready for your opBNB 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 opBNB RPC and API.

Get started

GLOBAL NODES Start fast with Global opBNB RPC Nodes

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

Best throughput

Never be short on resources when you need them. Enjoy the highest throughput in the industry, regardless of traffic volumes. Need to handle a massive influx? Go for it.

Learn more

No daily request limits

All our plans include class-leading monthly request volumes with no limits on the number or type of requests your DApp can make every day. Daily request limits? Who needs that?

Learn more

Global endpoint locations

Geo-load-balanced and distributed worldwide, Global Nodes automatically route requests to the nearest geo-located servers for the fastest service seamlessly.

Learn more

Unbeatable pricing

No method-specific fees. To make your monthly infra spending predictable, every API call to your node is billed at a flat rate in Request Units, or RU irrespective of the type of request or the computational resources it requires.

Notes for opBNB API

When communicating with an opBNB node, the client implements a JSON-RPC specification based on the OP Stack. The recommended libraries are ethers.js for JavaScript or web3.py for Python.

BNB Chain's L2 built on the OP Stack, offering lower fees for high-throughput applications.

You can also access opBNB directly through the Chainstack MCP server — query live on-chain data, deploy nodes, request testnet funds from the faucet, and search Chainstack docs from Claude, Cursor, Windsurf, ChatGPT, Codex, Pi, Gemini, or any MCP-compatible or SKILL-compatible AI agent.
