&#x20;***Install dependencies***

<pre class="language-bash"><code class="lang-bash"># Update the repositories
<strong>sudo apt update &#x26;&#x26; sudo apt upgrade -y
</strong></code></pre>

```bash
# Install developer packages
sudo apt install curl git wget htop tmux build-essential jq make lz4 gcc unzip -y
```

```bash
# Install Go
sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.24.6.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)
eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version
```

## ***Automatic Installation***

```bash
source <(curl -s https://raw.githubusercontent.com/validexisinfra/Celestia/main/setup_bridge_testnet.sh)
```

## ***Manual Installation***

```bash
# Download binary files
cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node
cd celestia-node/
git checkout tags/v0.28.5-mocha
make build 
sudo make install 
make cel-key
```

<pre class="language-bash"><code class="lang-bash"># Initiaton
<strong>celestia bridge init --core.ip &#x3C;RPC_NODE_IP> --p2p.network mocha
</strong></code></pre>

Once you start the Bridge Node, a wallet key will be generated for you. You will need to fund that address with Testnet tokens to pay for PayForBlob transactions. You can find the address by running the following command:

```bash
cd $HOME/celestia-node
./cel-key list --node.type bridge --keyring-backend test --p2p.network mocha
```

```bash
# Create service file
sudo tee /etc/systemd/system/celestia-bridge.service > /dev/null <<EOF
