# Developer Guides

- [Deploy Solidity Contracts](https://docs.rome.builders/developer-guides/deploy-solidity.md): Deploy Solidity smart contracts on Solana with Hardhat or Foundry — Rome network configuration, funded accounts, and step-by-step deployment.
- [Open your contract to Solana users](https://docs.rome.builders/developer-guides/open-to-solana-users.md): Deploy a Solidity contract on Rome (Hadrian testnet, Rubicon mainnet) and open it to Solana wallets — what the contract needs, how a Solana wallet user calls it, per-network addresses, and a launch ch
- [Verify Contracts](https://docs.rome.builders/developer-guides/verify-contracts.md): Verify Solidity contract source on Rome via the hosted Sourcify service — standard forge verify-contract and hardhat-verify flows, badges on the Via explorer.
- [WebSocket Subscriptions](https://docs.rome.builders/developer-guides/websocket-subscriptions.md): Subscribe to Rome EVM events over WebSocket — eth\_subscribe with newHeads and logs, working out of the box with ethers; with viem, use polling.
- [Call Solana from EVM](https://docs.rome.builders/developer-guides/call-solana-from-evm.md): Call Solana programs from Solidity via Rome's CPI and helper precompiles.
- [Call EVM from Solana](https://docs.rome.builders/developer-guides/call-evm-from-solana.md): Let a Solana wallet drive EVM contracts on Rome — no Ethereum key. The wallet signs, and its transaction goes to Solana.
- [Integrate a Solana program](https://docs.rome.builders/developer-guides/integrate-solana-program.md): Integrate a Solana program with Rome EVM — who the Solana signer is, how value reaches your program and comes back, the one-track rule, atomic vs iterative, and account provisioning.
- [Build a dual-lane app](https://docs.rome.builders/developer-guides/dual-lane-app.md): A step-by-step walkthrough of a dual-lane app — one Solidity contract used by both a MetaMask user and a Solana wallet user, with exactly what happens at each step.
- [From home: reach Rome from another chain](https://docs.rome.builders/developer-guides/from-home.md): Let users on another chain reach your Rome app without leaving home — bring assets in, act, take them back out.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.rome.builders/developer-guides.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
