# Smart Contracts

The protocol is composed of four contracts, each with a single responsibility.

## The contracts

| Contract        | Responsibility                                                                          |
| --------------- | --------------------------------------------------------------------------------------- |
| `MarketFactory` | Deploy and register markets; whitelist collateral; fee config; `maxB` cap; set resolver |
| `Market`        | One K-outcome market: state machine, LMSR virtual liquidity, claim                      |
| `AgentIdentity` | Soulbound ERC-721, minted on claim                                                      |
| `FeeVault`      | Treasury + insurance pool; covers bounded shortfalls                                    |

## Deployment

* Deployed to **Robinhood Chain mainnet** (chain ID `4663`).
* Sample `Market` (K=2, `b = 10` USDG), `FeeVault`, and `AgentIdentity` are live.
* Resolver is the deployer/admin address.
* The FeeVault bankroll is seeded (\~10 USDG at deploy).

{% hint style="warning" %}
Contract addresses and source verification are published separately. An independent audit is required before significant TVL.

This is a high-level overview. The detailed architecture and developer documentation are kept separately from this user-facing guide.

# 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://docs.decider.market/documentation/project-information/smart-contracts.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.
