# Introduction

Inferra is a marketplace and an exchange for GPU compute, built on Solana.

You can rent a real GPU and pay for it in USDC, with the money held in an on-chain escrow that reaches the provider only after the machine is delivered. And you can trade the price of GPU time itself, the way you would trade any other commodity. Both sides run on one wallet, one token, and one live price for an hour of compute.

### Two products

**Inferra Cloud** is the marketplace. Pick a GPU model, pick a provider, and pay in USDC. Your payment sits in escrow until the machine is handed to you over SSH, so you are never out of pocket for compute you did not receive, and a provider is never paid for a machine they did not deliver.

**The Inferra terminal** is the exchange. Every GPU model carries a live price per hour, the Inferra Index. You can trade that price on spot markets or with leveraged perpetuals, and stake $INFERRA to earn a share of protocol fees.

### One ecosystem

The two products are not two companies. They share the same foundations.

* **One token.** [$INFERRA](/inferra-docs/the-ecosystem/the-usdinferra-token.md) is a fixed-supply token on Solana. It carries protocol value through staking and buyback, and providers bond it (or USDC) to list capacity.
* **One wallet.** Connect once, and the same wallet works to rent compute and to trade. It is non-custodial: you sign every transaction yourself, and nothing can move your funds without your signature.
* **One price.** The [GPU-hour index](/inferra-docs/the-ecosystem/the-gpu-hour-index.md) is the number a renter pays and a trader prices. Real demand for compute anchors the price, and trading the price is how the market discovers what an hour of an A5000 is worth.

### Where to go next

* To rent or provide compute, start with [Inferra Cloud](/inferra-docs/inferra-cloud/overview.md), then [Renting compute](/inferra-docs/inferra-cloud/renting-compute.md), [Becoming a provider](/inferra-docs/inferra-cloud/becoming-a-provider.md), [The delivery layer](/inferra-docs/inferra-cloud/the-delivery-layer.md), and [The escrow program](/inferra-docs/inferra-cloud/the-escrow-program.md).
* To trade the price of compute, start with the [Inferra terminal](/inferra-docs/inferra-terminal/overview.md), then [Spot markets](/inferra-docs/inferra-terminal/spot-markets.md), [Perpetuals and futures](/inferra-docs/inferra-terminal/perpetuals-and-futures.md), and [Staking and buyback](/inferra-docs/inferra-terminal/staking-and-buyback.md).
* For addresses and parameters, see [On-chain addresses](/inferra-docs/reference/on-chain-addresses.md) and [Mainnet vs devnet](/inferra-docs/reference/mainnet-vs-devnet.md). The [Glossary](/inferra-docs/glossary.md) defines every term.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://inferra.gitbook.io/inferra-docs/introduction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
