# Chainstack add-ons: marketplace extensions for RPC nodes

> Enhance your Chainstack RPC nodes with add-ons including debug and trace APIs, archive data access, and MEV protection for Ethereum and EVM chains.

Add-ons are [Marketplace](https://console.chainstack.com/marketplace) items that extend your Chainstack nodes with extra capabilities.

Current add-ons:

* [Warp transactions](/docs/warp-transactions) — route transaction submission through bloXroute for faster propagation and earlier block inclusion.
* [MEV protection](/docs/mev-protection) — shield transactions from front-running, sandwich attacks, and other value extraction.
* [Yellowstone gRPC Geyser plugin](/docs/yellowstone-grpc-geyser-plugin)
* [Unlimited Node](/docs/unlimited-node)

## Manage node add-ons

Node add-ons such as Warp transactions and MEV protection attach to a specific node. You manage them on the node's **Add-ons** tab.

<Steps>
  <Step title="Open the Add-ons tab">
    On Chainstack, open your node and select the **Add-ons** tab.
  </Step>

  <Step title="Install or manage the add-on">
    Click **Install** next to the add-on (or **Manage** if it's already installed), select a plan, and click **Apply changes**.
  </Step>
</Steps>

An add-on shows **Install** until you add it, and **Manage** once it's installed.

To remove a node add-on, open it from the **Add-ons** tab, click **Manage** > **Uninstall**, then type `delete app` and confirm. You can install it again later from the same tab.
