Send as many RPC calls as you need for a fixed monthly fee.

To enable Unlimited Node for your existing project, simply go to the Marketplace in the Chainstack console. From there, find the Unlimited Node add-on and select the RPS tier that best matches your needs—25, 100, 250, or 500 RPS.

Once purchased, you can apply the add-on to any node in your project. The node will instantly upgrade to Unlimited mode, allowing you to send unlimited requests within your selected RPS tier. There’s no need to redeploy or migrate—your existing infrastructure stays intact.

The Unlimited Node add-on is available starting from the Growth plan, so make sure your subscription level supports it.

Yes, you can. Chainstack allows you to top up your account balance using crypto. Once your balance is topped up, you can use it to purchase the Unlimited Node add-on through the Marketplace, just like any other service.

If you need help with topping up or supported assets, our support team is here to assist.

Your plan’s request quota remains available and can still be used by your other nodes, subgraphs, or services within the same subscription. The Unlimited Node operates independently with its own RPS capacity, so you get the best of both worlds—flat-fee unlimited access on one node, while still using your standard quota elsewhere.

Yes, you can. You’re free to delete the Unlimited Node add-on at any time. Once removed, your node will switch back to using your plan’s quota and will be billed per request as usual.

You’ll also receive a partial refund for the unused portion of your Unlimited Node subscription time, credited back to your account balance.
