How to Setup an AVS Operator

System Requirement

1. Install Dependecies

# Update & Install Packages
sudo apt update & sudo apt upgrade -y
sudo apt install ca-certificates zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev curl git wget make jq build-essential pkg-config lsb-release libssl-dev libreadline-dev libffi-dev gcc screen unzip lz4 -y

# Install Docker
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
docker version

# Install Docker-Compose
VER=$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep tag_name | cut -d '"' -f 4)

curl -L "https://github.com/docker/compose/releases/download/"$VER"/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose
docker-compose --version

# Docker Permission to user
sudo groupadd docker
sudo usermod -aG docker $USER

# Install Go
sudo rm -rf /usr/local/go
curl -L https://go.dev/dl/go1.22.4.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
echo 'export PATH=$PATH:$(go env GOPATH)/bin' >> $HOME/.bash_profile
source .bash_profile
go version

2. Install EigenLayer CLI

curl -sSfL https://raw.githubusercontent.com/layr-labs/eigenlayer-cli/master/scripts/install.sh | sh -s

export PATH=$PATH:~/bin

eigenlayer --version

3. Clone Chainbase AVS repo

git clone https://github.com/chainbase-labs/chainbase-avs-setup

cd chainbase-avs-setup/holesky

4. Create Eigenlayer wallet

Create a new Key

1- Create operator address

eigenlayer operator keys create --key-type ecdsa opr

2- Enter a password and press Enter

• Best symbol for password is * , you can choose a password like this: ***123ABCabc123***

3- Save your wallet private key

4- Ctrl+C+Enter+Enter & save your wallet info

Optional: Import an old key

Replace PRIVATEKEY

eigenlayer operator keys import --key-type ecdsa opr PRIVATEKEY

Enter a password and press Enter

Best symbol for password is * , you can choose a password like this: ***123ABCabc123***

Fund your Eigen wallet

You’ll need at least 1 Holesky ETH to cover the gas cost of the operator registration. Make sure to send at least 1 ETH to your Eigenlayer operator’s address

5. Config & register operator

eigenlayer operator config create

• operator address: Your Eigenlayer ETH address
• earnings address: press Enter
• ETH rpc url: https://ethereum-holesky-rpc.publicnode.com
• network: holesky
• signer type: local_keystore
• ecdsa key path:: /root/.eigenlayer/operator_keys/opr.ecdsa.key.json

6. Edit metadata.json

1- Open metadata.json edit menu

nano metadata.json

2- Complete your details in metadata.json

• logo: Must be raw link to your operator favorite logo
• Logo only supports .png file less than 1MB in size
• Create a repositry in github and upload .png there
• To get your logo raw link: 1) Navigate to the file in your repository, 2) Click on the file name to view its contents, 3) In the address bar of your browser, 4) replace blob with raw in the URL, 5) Press Enter to load the raw content view, 6) Copy the updated URL from the address bar and paste in front of logo field in metadata.json
• My example metadata.json file in github: https://github.com/choir94/Chainbase_Node_Tesnet/blob/main/metadata.json
• Ctrl+X+Y+Enter to save metadata.json

3- Upload metadata.json to your github repository and get its raw link like previous step

• You can create a metadata.json file in github with the contents of your file or you must download it from VPS using Termius or Mobaxterm ssh clients

4- Open operator.yaml edit menu

nano operator.yaml

5- Add your metadata.json raw url in github in front of metadata-url

7. Run Eigenlayer holesky Node

eigenlayer operator register operator.yaml

# Check status
eigenlayer operator status operator.yaml

8. Config Chainbase AVS

1- Create .env file

# Delete old files
rm -rf .env

# Open Edit menu
nano .env

2- Paste below codes in it

• NODE_ECDSA_KEY_PASSWORD: Replace ***123ABCabc123*** with your Eigenlayer password
• Optional: You can Change #TODO lines if needed but it should be okay by default

3- Create docker-compose.yml file

# Remove old file
rm -rf docker-compose.yml

# Open edit menu
nano docker-compose.yml

4- Paste below codes in it and save with CTRL+X+Y+ENTER

• You can change ports if any of them are in use: 8081, 9091, 8080, 9092
• If you want to change 8081 to 35081 then just change the port on the left side like: 35081:8081

5- Create folders for docker

source .env && mkdir -pv ${EIGENLAYER_HOME} ${CHAINBASE_AVS_HOME} ${NODE_LOG_PATH_HOST}

6- Give permissions to bash script

chmod +x ./chainbase-avs.sh

7- update prometheus.yml

• Replace ${YOUR_OPERATOR_NAME} with your operator address

nano prometheus.yml

9. Run Chainbase AVS

1- Register AVS

./chainbase-avs.sh register

2- Run AVS

./chainbase-avs.sh run

10. Check AVS health

Check chainbase-node logs

docker compose logs chainbase-node -f

Get your AVS link

export PATH=$PATH:~/bin

eigenlayer operator status operator.yaml

Check Operator Health

# If your port is 8080
curl -i localhost:8080/eigen/node/health

Check docker containers

• You must have 4 new docker containers

docker ps -a
