# Overview

Rome runs multiple public chains. Two are the ones to build against today: **Martius** (testnet) and **Hadrian** (devnet). Both are EVM chains that execute inside a Solana program and settle on Solana Devnet, so devnet SOL is not real money.

| Network                                   | Chain ID | RPC                                         | Explorer                                                     | Gas token |
| ----------------------------------------- | -------- | ------------------------------------------- | ------------------------------------------------------------ | --------- |
| [Martius](/networks/martius.md) (testnet) | 121214   | `https://martius.testnet.romeprotocol.xyz/` | [via-martius](https://via-martius.testnet.romeprotocol.xyz/) | USDC      |
| [Hadrian](/networks/hadrian.md) (devnet)  | 200010   | `https://hadrian.testnet.romeprotocol.xyz/` | [via-hadrian](https://via-hadrian.testnet.romeprotocol.xyz/) | USDC      |
| Local                                     | 1001     | `http://localhost:9090`                     | —                                                            | —         |

Chain metadata — chain IDs, contract addresses, token mints, gas pools — is canonical in the [Rome registry](https://github.com/rome-protocol/rome-registry). Don't hardcode addresses; read them from there.

## Add a network to your wallet

Each network page lists the manual MetaMask values. WebSocket subscriptions are served on the same host as the HTTPS RPC (swap `https://` for `wss://`).

## Fund a wallet

Rome's public chains settle on Solana Devnet. Get devnet SOL from the [Solana faucet](https://faucet.solana.com/), then obtain a chain's gas token through the [Rome App](https://app.testnet.romeprotocol.xyz) (wrap/bridge). For test tokens on every chain the bridge supports, see [Faucets](/resources/faucets.md).

## Local development

Develop against a public chain today — see the [Quickstart](/getting-started/quickstart.md). A self-contained local stack (chain ID 1001, Proxy on `:9090`) is on the roadmap.

## 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.rome.builders/networks/networks.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.
