Two Testnets in One! Be the first to support Mangata’s roll-up with EigenLayer

The very first version of Mangata’s AVS testnet, based on the EigenLayer omnichain zk-rollup, is now live! This marks a crucial step towards the launch of their mainnet on Ethereum via EigenLayer in 2024

Introduction

Mangata is deploying its first omnichain zk-rollup on the Ethereum Goerli testnet, utilizing ETH restaked from EigenLayer for its security.

https://www.mangata.finance/

Mangata is an omnichain zk-rollup offering L1-grade native liquidity with the goal of making tokens from all ecosystems tradable. To date, Mangata has raised a total of $5.6 million, and its current valuation is $60 million.

Mangata invites EigenLayer operators to join the testnet journey starting today. Exciting opportunities and a reward system will be available for testers in the future.

∘ 3- Installation of Essential Components
∘ 4- Downloading the Mangata Folder

1- VPS Configuration

To set up your masternode, you have the choice of hosting it on your own computer or opting for a Virtual Private Server (VPS), which is ideal for hosting websites, applications, or other online services, such as nodes.

In my case, I opted for Contabo, a reputable VPS rental solution.
I have no information about the requested configuration. Considering an intermediate VPS configuration could be an interesting option to consider

So, I recommend you choose the Cloud VPS 2.

Now it’s your turn…

To order your Contabo VPS, you can click on this link.

It’s an affiliate link, with no additional cost to you, which allows me to support my work and provide valuable content.

Les offres de Contabo

Opt for a 400 GB SSD storage capacity and choose the Docker image for your configuration.

Once you have completed the payment process, you will receive an order confirmation email. Please wait to receive a second email containing information about your VPS, including your login credentials.

To connect to your VPS, I recommend following this detailed tutorial. You will need to download the Putty software, which will allow you to establish a secure connection with your VPS and access its features.

2- Creating your operator on EigenLayer

In order to launch your Mangata node, you will create your operator on the EigenLayer testnet.

To do this, follow step 2 of my guide.

To be able to launch your Mangata node, you will need to have a minimum of one gETH restacked on your Operator.

3- Installation of Essential Components

Before delving into the installation of your node, it is crucial to update your VPS.
To do so, simply execute the following command in your VPS terminal:

sudo apt-get update && sudo apt-get upgrade -y

Copy the command and right-click in your terminal to paste it.

Now, you need to proceed with installing Docker.

Docker is a platform for running applications in “containers”, which makes it easy to deploy and run them on different machines without worrying about configuration differences.

To do this, run the following command in your terminal:

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

Then :

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

And :

systemctl start docker

4- Downloading the Mangata Folder

You will be able to download the Mangata folder:

git clone https://github.com/mangata-finance/avs-operator-setup.git
cd avs-operator-setup
chmod +x run.sh

5- Configuring Your Node

You will configure your node according to your operator on EigenLayer.

nano .env

You will open a file containing this text. Modify the elements with angle brackets <…> with the information from your EigenLayer operator.
Navigate through the text using the arrow keys on your keyboard.
You can find an API at https://www.infura.io/ :

To exit your file, hold down CTRL+X, then press Y and ENTER.

Update the folder:

./run.sh opt-in

6- Launching the Node

Now that you have configured your folder, you can launch the node.

docker compose up -d

You can check the log of your node with the command:

docker logs -f avs-finalizer-node

Congratulations, your node is launched, and you are securing the Mangata roll-up with your ETH restaked on EigenLayer!
