GO

wget https://go.dev/dl/go1.22.6.linux-amd64.tar.gz && \sudo rm -rf /usr/local/go && \sudo tar -C /usr/local -xzf go1.22.6.linux-amd64.tar.gz && \echo "export PATH=\$PATH:/usr/local/go/bin" >> ~/.profile && \source ~/.profile && \go version

2. Install CLI Using GO

go install github.com/Layr-Labs/eigenlayer-cli/cmd/eigenlayer@latest

export PATH=$HOME/go/bin:$PATHecho 'export PATH=$HOME/go/bin:$PATH' >> ~/.profilesource ~/.profile

eigenlayer --version

3. Create New Operator Wallet

echo "password" | eigenlayer operator keys create --key-type ecdsa keyname

• Password . Must be combination of uppercase, lowercase, numbers and symbols

• Keyname Change with your own

• Copy Private Key

• Press q

• Copy your Ethereum Address

4. Check Wallet

eigenlayer operator keys list

5. Claim Faucet

• You need at least 1 ETH Holesky to cover the gas cost of the operator registration.

• Claim at : https://holesky-faucet.pk910.de/ | https://www.holeskyfaucet.io/ | https://www.holeskyfaucet.io/

6. Configure Your Operator

eigenlayer operator config create

• Enter your Operator Address

• Earning Address , Just press Enter

• RPC ETH Holesky, you can find at : https://chainlist.org/chain/17000 or use your own RPC.

• Select Network Holesky

• Select Local Keystore

• Look for your ECDSA Key file path

• Mine is in : /root/.eigenlayer/operator_keys/stakenode.ecdsa.key.json

• Copy and Paste the directory link above.

7. Look for Metadata.json file

• nano metadata.json

• Edit and fill up with your Data, like Name, Website, Description, Twitter

• You can upload your logo to your Github Repository.

• Copy its Raw link.

• Done and Save ctrl x y enter

8. RPC URL Configuration

curl -I Change-with-URL-RPC

9. Create Metadata URL

• Upload content of your Metadata.json to GitHub and copy its RAW link.

• Input in operator.yaml at metadata_url section and Save

• Done

10. Update operator.yaml

eigenlayer operator update operator.yaml

• Insert your Password

• If you got "Operator Not Register"

• You need to register first by using the following command :

eigenlayer operator register operator.yaml

• Insert your Password

• Done

11. Install Chainbase-AVS-CLI

wget https://github.com/chainbase-labs/chainbase-avs-contracts/releases/download/v0.1.9-ci-test/chainbase-node_Linux_x86_64.tar.gz && \tar -xzf chainbase-node_Linux_x86_64.tar.gz && \sudo mv chainbase-node /usr/local/bin/ && \sudo chmod +x /usr/local/bin/chainbase-node && \rm chainbase-node_Linux_x86_64.tar.gz

12. Chainbase AVS Contract Registration

git clone https://github.com/chainbase-labs/chainbase-avs-setup && cd chainbase-avs-setup/holesky mv .env.example .env

Edit nano .env

1. Make sure the folder is there and you have permission to run docker.

cd chainbase-avs-setup/holeskysource .env && mkdir -pv ${EIGENLAYER_HOME} ${CHAINBASE_AVS_HOME} ${NODE_LOG_PATH_HOST}

2. Confirm the latest image version of avs chainbase and edit on env file

MAIN_SERVICE_IMAGE=repository.chainbase.com/network/chainbase-node:v0.1.9-ci-test

3. Change the access permissions of chainbase-avs.sh

chmod +x ./chainbase-avs.sh

4. Change YOUR_OPERATOR_NAME with your Operator name

nano premetheus.yml

13. Register Chainbase AVS

./chainbase-avs.sh register

14. Run Chainbase AVS

./chainbase-avs.sh run

15. Check Chainbase AVS Logs

docker compose logs chainbase-node -f

Check Node Health

curl -i localhost:8080/eigen/node/health

Get Operator Link
