### 1. Port

```
sudo ufw allow ssh & sudo ufw allow 30333 && sudo ufw allow 8078 && sudo ufw enable
```

### 2. Create User

**a. Add user `flip`**

```
sudo useradd -s /bin/bash -d /home/flip/ -m -G sudo flip 
```

**b. Add password**

```
sudo passwd flip
```

> Masukan password baru yang mudah diingat, samakan dengan password VPS mu atau tanggal lahir terserah. **YANG PENTING JANGAN LUPA**

**c. Setup dasar untuk `flip`**

```
mkdir /home/flip/.ssh
sudo chown -R flip:flip /home/flip/.ssh/
sudo chmod 0700 /home/flip/.ssh/
```

* Untuk login menggunakan user `flip`

```html
ssh flip@<IP.VPS.MU>
```

IP.VPS.MU = ya IP VPS mu

* Berpindah dari `root` ke `flip`

```
su - flip
```

### 3. Download & Install Chainflip

**a. Download Chainflip GPG key**

```
sudo mkdir -p /etc/apt/keyrings
curl -fsSL repo.chainflip.io/keys/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/chainflip.gpg
```

echo "deb [signed-by=/etc/apt/keyrings/chainflip.gpg] https://repo.chainflip.io/perseverance/ focal main" | sudo tee /etc/apt/sources.list.d/chainflip.list
```

**c. Install Chainflip**

```
sudo apt-get update
sudo apt-get install -y chainflip-cli chainflip-node chainflip-engine
```

### 4. Import Metamask Wallet

**a. Buat wallet baru di Metamask, isi dengan 0.1 ETH Goerli, lalu request faucet di Discord**

Jangan lupa untuk ambil role ,supaya bisa claim faucet

<figure><img src="/files/xLOkES6vMqqTjMxYjbyf" alt=""><figcaption></figcaption></figure>

> !drip \<AddressMU>

**b. Buat folder keys**

```
sudo mkdir /etc/chainflip/keys
```

**c. Import wallet ke VPS**

{% hint style="danger" %} <mark style="color:red;">**NEW WALLET**</mark> karena yang di import  Private Key, jadi jangan gunakan wallet utama

<mark style="color:red;">**HARUS**</mark> Private Key dari Metamask
{% endhint %}

```html
echo -n "<PRIVATE_KEY_MU>" |  sudo tee /etc/chainflip/keys/ethereum_key_file
```

> Ganti `<PRIVATE_KEY_MU>` dengan PrivKey mu
>
> Dan pastikan wallet yang di import adalah wallet yang berisi 0.1 Goerli dan yang digunakan untuk request faucet tadi

**d. Buat signin\_key**

```
chainflip-node key generate
```

Output:

```
Secret phrase:       never gonna give you up let you down make you cry round around
  Network ID:        2112
  Secret seed:       0x000000000000000000000000000000000000000  # This is your private key. Hold onto it.
  Public key (hex):  0x000000000000000000000000000000000000DEAD
  Account ID:        0x000000000000000000000000000000000000DEAD 
  Public key (SS58): cFAzeakmiHesoyamAbogoboga # This is your Validator ID. Make sure you have it handy for staking.
  SS58 Address:      cFAzeakmiHesoyamAbogoboga
```

{% hint style="danger" %} <mark style="color:red;">**BACKUP**</mark>
{% endhint %}

**e. Simpan signin\_key**

```html
SECRET_SEED=<SECRET_SEED Tanpa 0x>
```

```
echo -n "${SECRET_SEED:2}" | sudo tee /etc/chainflip/keys/signing_key_file
```

**f. Generate node\_key**

```
sudo chainflip-node key generate-node-key --file /etc/chainflip/keys/node_key_file
```

untuk melihat `node_key` gunakan command

```
cat /etc/chainflip/keys/node_key_file
```

**g. Backup folder** `/etc/chainflip/keys/`

**h. Hapus permission user lain**

```
sudo chmod 600 /etc/chainflip/keys/ethereum_key_file
sudo chmod 600 /etc/chainflip/keys/signing_key_file
sudo chmod 600 /etc/chainflip/keys/node_key_file
history -c
```

### 5. Membuat Config

**a. Register Alchemy**

[**DISINI**](https://dashboard.alchemy.com/)

**b. Create App**

**c. Pilih Chain Ethereum dan Network Goerli (Nama dan Deskripsi bebas)**

<figure><img src="/files/IUDDFu5HjSU8EkvphtnI" alt=""><figcaption></figcaption></figure>

**d. Masuk ke App**

**e. Klik View Key dan simpan ke notepad**

<figure><img src="/files/Sndyr4Ekpj46alSwc0yr" alt=""><figcaption></figcaption></figure>

**Tambahan**: Yang `https` itu bisa digunakan untuk RPC URL di metamask

{% hint style="danger" %}
Jangan berikan kepada siapapun karena itu RPC + API Keys pribadi mu
{% endhint %}

**f. Kembali ke VPS dan pastikan masih menggunakan user** `flip` **bukan** `root`

**g. Buat folder dan file baru**

* Buat folder config

```
sudo mkdir -p /etc/chainflip/config
```

* Buat file `Defaul.toml`

```
sudo nano /etc/chainflip/config/Default.toml
```

&#x20;  Isi menggunakan ini

```markup
# Default configurations for the CFE
[node_p2p]
node_key_file = "/etc/chainflip/keys/node_key_file"
ip_address="IP.VPS.MU"
port = "8078"

[state_chain]
ws_endpoint = "ws://127.0.0.1:9944"
signing_key_file = "/etc/chainflip/keys/signing_key_file"

[eth]
# Ethereum RPC endpoints (websocket and http for redundancy).
ws_node_endpoint = "wss://dari-alchemy"
http_node_endpoint = "https://dari-alchemy"

# Ethereum private key file path. This file should contain a hex-encoded private key.
private_key_file = "/etc/chainflip/keys/ethereum_key_file"

[signing]
db_file = "/etc/chainflip/data.db"
```

> * Ganti `IP.VPS.MU` dengan IP VPS mu
> * Ganti  `wss://dari-alchemy` dengan link WEBSOCKETS mu dari alchemy
> * Ganti `https://dari-alchemy` dengan link HTTPS mu dari alchemy
