# Deploy Kontrak Solidity

Panduan ini membahas deployment kontrak pintar Solidity di Rome EVM menggunakan Hardhat dan Foundry.

## Prasyarat

* Node.js v18+ (Hardhat) atau Foundry terinstal
* Alamat Rome EVM yang telah didanai (lihat [Panduan Cepat](/id/memulai/quickstart.md))
* Private key Anda diekspor sebagai variabel lingkungan

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

## Konfigurasi Jaringan

| Jaringan          | RPC URL                                      | Chain ID |
| ----------------- | -------------------------------------------- | -------- |
| Lokal             | `http://localhost:9090`                      | `1001`   |
| Devnet (montispl) | `https://montispl.devnet.romeprotocol.xyz`   | `200002` |
| Testnet (Martius) | `https://martius-i.testnet.romeprotocol.xyz` | `121214` |
| Testnet (Caelian) | `https://caelian-i.testnet.romeprotocol.xyz` | `121215` |

## Hardhat

### Setup

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

### hardhat.config.js

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

module.exports = {
  solidity: {
    version: "0.8.28",
    settings: {
      optimizer: { enabled: true, runs: 200 },
    },
  },
  networks: {
    rome_local: {
      url: "http://localhost:9090",
      chainId: 1001,
      accounts: [process.env.PRIVATE_KEY],
    },
    rome_devnet: {
      url: "https://montispl.devnet.romeprotocol.xyz",
      chainId: 200002,
      accounts: [process.env.PRIVATE_KEY],
    },
    rome_martius: {
      url: "https://martius-i.testnet.romeprotocol.xyz",
      chainId: 121214,
      accounts: [process.env.PRIVATE_KEY],
    },
    rome_caelian: {
      url: "https://caelian-i.testnet.romeprotocol.xyz",
      chainId: 121215,
      accounts: [process.env.PRIVATE_KEY],
    },
  },
};
```

### Deploy

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

### Verifikasi di Block Explorer

```bash
npx hardhat verify --network rome_martius 0xCONTRACT_ADDRESS
```

## Foundry

### Setup

```bash
forge init my-rome-project
cd my-rome-project
```

### Deploy

```bash
# Lokal
forge create --rpc-url http://localhost:9090 \
  --private-key $PRIVATE_KEY \
  src/Counter.sol:Counter

# Devnet
forge create --rpc-url https://montispl.devnet.romeprotocol.xyz \
  --private-key $PRIVATE_KEY \
  src/Counter.sol:Counter
```

### Panggil Kontrak yang Dideploy

```bash
# Baca
cast call 0xCONTRACT_ADDRESS "number()" \
  --rpc-url https://montispl.devnet.romeprotocol.xyz

# Tulis
cast send 0xCONTRACT_ADDRESS "increment()" \
  --rpc-url https://montispl.devnet.romeprotocol.xyz \
  --private-key $PRIVATE_KEY
```

## Menggunakan Rome Solidity SDK

Untuk kontrak yang berinteraksi dengan program Solana, instal Rome Solidity SDK:

```bash
npm install @rome-protocol/solidity-sdk
```

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

import {SplToken, CpiProgram, SystemProgram} from "@rome-protocol/solidity-sdk/contracts/core/Precompiles.sol";
import {SPL_ERC20} from "@rome-protocol/solidity-sdk/contracts/token/ERC20SPL.sol";
import {RomeEVMAccount} from "@rome-protocol/solidity-sdk/contracts/core/RomeEVMAccount.sol";

contract MyRomeContract {
    // Membaca saldo token SPL pengguna dari Solana
    function getSolanaBalance(bytes32 mint) external view returns (uint64) {
        bytes32 userPda = RomeEVMAccount.pda(msg.sender);
        ISplToken.Account memory account = SplToken.account_state(userPda);
        return account.amount;
    }

    // Memanggil program Solana apa pun melalui CPI
    function callSolanaProgram(
        bytes32 programId,
        ICrossProgramInvocation.AccountMeta[] calldata accounts,
        bytes calldata data
    ) external {
        CpiProgram.invoke(programId, accounts, data);
    }
}
```

## Batasan Deployment

| Batasan                 | Batas                   | Catatan                                                               |
| ----------------------- | ----------------------- | --------------------------------------------------------------------- |
| Ukuran maksimum kontrak | 480 KB                  | Dinaikkan dari 24 KB Ethereum untuk mode OP-Geth                      |
| Batas ukuran transaksi  | 80 KB per holder        | Deploy besar dibagi secara transparan ke seluruh akun holder          |
| Anggaran komputasi      | \~1,4M CU (atomik)      | Gunakan mode iteratif untuk kontrak yang berat                        |
| Versi Solidity          | 0.8.28 direkomendasikan | Versi yang lebih lama tetap berfungsi, tetapi 0.8.28 cocok dengan SDK |

## Kesalahan Umum

| Kesalahan                    | Penyebab                        | Perbaikan                                             |
| ---------------------------- | ------------------------------- | ----------------------------------------------------- |
| `dana tidak cukup untuk gas` | Alamat EVM tidak memiliki saldo | Setorkan SOL melalui UI deposit                       |
| `nonce terlalu rendah`       | Nonce lama di wallet            | Reset akun MetaMask atau tentukan nonce secara manual |
| `execution reverted`         | Logika kontrak gagal            | Debug dengan `eth_call` atau `forge test --fork-url`  |
| `transaction underpriced`    | Harga gas di bawah minimum      | Tingkatkan harga gas dalam transaksi                  |
