Unlimited Node add-on

Enable the Unlimited Node add-on to convert any existing Chainstack RPC node into a flat-fee endpoint with predictable monthly costs and capped capacity.

The Unlimited Node add-on turns any existing Chainstack RPC node into a flat-fee endpoint. You pick an RPS tier, enable the add-on, and the node stops consuming plan request quota — replaced by a predictable monthly bill.

Available RPS tiers

• 25 RPS
• 100 RPS
• 250 RPS
• 500 RPS
• 1000 RPS

Why use it

• Fixed monthly cost — no per-request billing, no overage math.
• Zero plan quota usage — the attached node stops drawing from your plan request pool, freeing those requests for other nodes.
• No extra usage required — overage and extra usage settings do not apply to an Unlimited Node. Traffic above the tier limit is rate-limited rather than billed.
• Available from the Growth plan and up.

Enable the add-on

1. In the Chainstack console, open Nodes and select the node you want to convert.
2. Click Add-ons > Unlimited Node.
3. Pick an RPS tier and click Apply changes.
4. Confirm payment. The add-on activates within seconds.
