# Frequently asked questions

> Answers to common questions about Blockops, the Blockchain API, Mission Control and Telescope.

## Blockops

<AccordionGroup>
  <Accordion title="What is Blockops?">
    Blockops provides core banking infrastructure for digital assets: an MPC wallet platform built for financial institutions, and the blockchain infrastructure it runs on: RPC endpoints, managed nodes, indexing, monitoring and dedicated rollups.
  </Accordion>

  <Accordion title="How do I get started?">
    Follow [Getting started](/get-started/overview): create an account, create a project, and make your first request. Each product then has its own guide.
  </Accordion>

  <Accordion title="How is support provided?">
    Email [hello@blockops.network](mailto:hello@blockops.network), use the support icon at the bottom right of the dashboard, or ask the community on [Discord](https://discord.com/invite/nngqxkqdw8). See [Support](/get-started/support).
  </Accordion>
</AccordionGroup>

## Accounts and access

<AccordionGroup>
  <Accordion title="How do I sign up?">
    With Google, GitHub, or an email address. Email sign-up asks for a business name, your name, an email address and a password, and requires email verification. See [Create your account](/get-started/create-your-account).
  </Accordion>

  <Accordion title="What do I do if my API key is exposed?">
    Rotate it. Open the project in the dashboard and use **Rotate Key**; the old key stops working immediately. See [Endpoints, keys & authentication](/blockchain-infrastructure/blockchain-api/endpoints-and-authentication).
  </Accordion>
</AccordionGroup>

## Blockchain API

<AccordionGroup>
  <Accordion title="Which networks does the Blockchain API support?">
    The full list is on [Supported networks & assets](/overview/supported-networks), with a connection guide for each network that has one.
  </Accordion>

  <Accordion title="How do I authenticate requests?">
    With your project's API key, either in the `authorization: APIKEY <key>` header or as the `?api_key=<key>` query string. Both HTTP and WebSocket endpoints accept either form.
  </Accordion>

  <Accordion title="What are the request limits?">
    Public endpoints allow 50 requests per second and are intended for testing only. Private endpoints, which use your API key, allow 1000 requests per second. If you need more, contact support. See [Rate limits & error codes](/blockchain-infrastructure/blockchain-api/rate-limits-and-errors).
  </Accordion>

  <Accordion title="How do I handle errors?">
    The API returns standard HTTP status codes: `401` for a missing or invalid key, `404` for an unknown route, `429` when you exceed the request limit, and `500` for a server-side error. Network-specific errors come back in the JSON-RPC response body. See [Rate limits & error codes](/blockchain-infrastructure/blockchain-api/rate-limits-and-errors).
  </Accordion>
</AccordionGroup>

## Mission Control

<AccordionGroup>
  <Accordion title="What is Mission Control?">
    The Blockops service for deploying and managing blockchain nodes. Nodes can run on Google Cloud, AWS, Cherry Servers, bare metal, or a private server you connect over an SSH tunnel. See [Node operations](/blockchain-infrastructure/node-operations/overview).
  </Accordion>

  <Accordion title="How many nodes do I need to start?">
    One. You can start with a single node and add more later.
  </Accordion>

  <Accordion title="Can I deploy to servers I already own?">
    Yes. Bare-metal servers are reached over SSH; servers without inbound access are connected through an outbound SSH tunnel. See [Deploy to your own servers](/blockchain-infrastructure/node-operations/deploy-to-your-own-servers).
  </Accordion>
</AccordionGroup>

## Telescope

<AccordionGroup>
  <Accordion title="What does Telescope monitor?">
    Metrics, logs, uptime and alerts for deployed nodes, through a Node Health Dashboard for individual nodes and a Network Dashboard for a network. Metrics are collected by push, where Blockops exposes an endpoint for you, or by pull from a datasource you provide. See [Monitoring & alerting](/blockchain-infrastructure/monitoring-and-alerting).
  </Accordion>

  <Accordion title="How do alerts reach me?">
    Alerts are created on a dashboard (metrics or logs) or on an uptime monitor and are delivered to the contact points you configure.
  </Accordion>

  <Accordion title="Can I monitor several nodes at once?">
    Yes. Each node you deploy can be added to Telescope, and the Network Dashboard covers a network as a whole.
  </Accordion>
</AccordionGroup>

## Pulsar and Rollups

<AccordionGroup>
  <Accordion title="What is Pulsar?">
    A managed indexing service. You deploy SubQuery or The Graph indexers and query them through a GraphQL endpoint, without running the indexer infrastructure yourself. See [Indexing](/blockchain-infrastructure/indexing).
  </Accordion>

  <Accordion title="What is a Blockops Rollup?">
    A dedicated OP Stack Layer 2 chain that settles to Ethereum. Testnet rollups deploy to Ethereum Sepolia and are self-serve; mainnet rollups settle to Ethereum Mainnet and are set up with the Blockops team. See [Rollups](/blockchain-infrastructure/rollups).
  </Accordion>
