# Panduan Cepat

Deploy kontrak Solidity pertama Anda di Rome EVM dalam waktu kurang dari 5 menit.

## Prasyarat

* [Node.js](https://nodejs.org/) v18+
* [MetaMask](https://metamask.io/) ekstensi browser
* Dompet Solana dengan devnet SOL (untuk gas)

## 1. Tambahkan Jaringan Rome ke MetaMask

Buka MetaMask → Settings → Networks → Add Network:

| Field            | Nilai                                      |
| ---------------- | ------------------------------------------ |
| Nama Jaringan    | Rome Devnet                                |
| RPC URL          | `https://montispl.devnet.romeprotocol.xyz` |
| Chain ID         | `200002`                                   |
| Simbol Mata Uang | `RSOL`                                     |
| Block Explorer   | —                                          |

## 2. Isi Dompet Anda

Setorkan devnet SOL ke alamat Rome EVM Anda melalui [UI deposit](https://deposit.devnet.romeprotocol.xyz). Hubungkan dompet Solana Anda (dengan devnet SOL) dan MetaMask Anda, lalu masukkan jumlah yang ingin disetorkan. UI mengonversi SOL ke RSOL dengan rasio 1:1 dan mengkredit alamat EVM Anda.

## 3. Buat Proyek Hardhat

```bash
mkdir rome-hello && cd rome-hello
npm init -y
npm install --save-dev hardhat @nomicfoundation/hardhat-toolbox
npx hardhat init
```

Pilih "Create a JavaScript project" saat diminta.

## 4. Konfigurasikan Hardhat untuk Rome

Edit `hardhat.config.js`:

```javascript
require("@nomicfoundation/hardhat-toolbox");

module.exports = {
  solidity: "0.8.28",
  networks: {
    rome_devnet: {
      url: "https://montispl.devnet.romeprotocol.xyz",
      chainId: 200002,
      accounts: [process.env.PRIVATE_KEY],
    },
    rome_local: {
      url: "http://localhost:9090",
      chainId: 1001,
      accounts: [process.env.PRIVATE_KEY],
    },
  },
};
```

Ekspor private key MetaMask Anda:

```bash
export PRIVATE_KEY="0xPRIVATE_KEY_ANDA"
```

## 5. Tulis Kontrak

Buat `contracts/HelloRome.sol`:

```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.28;

contract HelloRome {
    string public greeting = "Halo dari Solana!";
    uint256 public counter;

    event Greeted(address indexed sender, uint256 count);

    function greet() external returns (string memory) {
        counter++;
        emit Greeted(msg.sender, counter);
        return greeting;
    }

    function setGreeting(string calldata _greeting) external {
        greeting = _greeting;
    }
}
```

## 6. Deploy

Buat `scripts/deploy.js`:

```javascript
const hre = require("hardhat");

async function main() {
  const HelloRome = await hre.ethers.getContractFactory("HelloRome");
  const hello = await HelloRome.deploy();
  await hello.waitForDeployment();

  const address = await hello.getAddress();
  console.log("HelloRome deployed to:", address);

  // Panggil kontraknya
  const tx = await hello.greet();
  await tx.wait();

  const count = await hello.counter();
  console.log("Penghitung:", count.toString());

  const greeting = await hello.greeting();
  console.log("Sapaan:", greeting);
}

main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});
```

Deploy ke Rome devnet:

```bash
npx hardhat run scripts/deploy.js --network rome_devnet
```

Output yang diharapkan:

```
HelloRome deployed to: 0x5FbDB2315678afecb367f032d93F642f64180aa3
Penghitung: 1
Sapaan: Halo dari Solana!
```

Kontrak Solidity Anda sekarang berjalan di Solana.

## Kesalahan Umum

| Kesalahan              | Penyebab                           | Perbaikan                                                       |
| ---------------------- | ---------------------------------- | --------------------------------------------------------------- |
| `dana tidak mencukupi` | Alamat EVM tidak memiliki saldo    | Setorkan SOL melalui UI deposit                                 |
| `nonce terlalu rendah` | Ketidaksesuaian nonce transaksi    | Atur ulang akun MetaMask (Settings → Advanced → Clear Activity) |
| `execution reverted`   | Eksekusi kontrak gagal             | Periksa logika kontrak; gunakan `eth_call` untuk men-debug      |
| Connection timeout     | Endpoint RPC tidak dapat dijangkau | Verifikasi URL jaringan; periksa apakah devnet beroperasi       |
