Clone zenrock-validators repository

cd $HOME
rm -rf zenrock-validators
git clone https://github.com/zenrocklabs/zenrock-validators

Generate keys

Set key password

read -p "Enter password for the keys: " key_pass

Create sidecar directories

mkdir -p $HOME/.zrchain/sidecar/bin
mkdir -p $HOME/.zrchain/sidecar/keys

Build ecdsa binary

cd $HOME/zenrock-validators/utils/keygen/ecdsa && go build

Build bls binary

cd $HOME/zenrock-validators/utils/keygen/bls && go build

Generate ecdsa key

ecdsa_output_file=$HOME/.zrchain/sidecar/keys/ecdsa.key.json
ecdsa_creation=$($HOME/zenrock-validators/utils/keygen/ecdsa/ecdsa --password $key_pass -output-file $ecdsa_output_file)
ecdsa_address=$(echo "$ecdsa_creation" | grep "Public address" | cut -d: -f2)

Generate bls key

bls_output_file=$HOME/.zrchain/sidecar/keys/bls.key.json
$HOME/zenrock-validators/utils/keygen/bls/bls --password $key_pass -output-file $bls_output_file

Output

echo "ecdsa address: $ecdsa_address"

Set operator configuration

Don't forget Ensure that you have configured TESTNET_HOLESKY_ENDPOINT, MAINNET_ENDPOINT, ETH_RPC_URL, ETH_WS_URL with your specific values. You can use Quicknode.com to get api keys. I used infura.io (but ffter Metamask acquired Infura they significantly reduced their limits)

Declare variables

EIGEN_OPERATOR_CONFIG="$HOME/.zrchain/sidecar/eigen_operator_config.yaml"
TESTNET_HOLESKY_ENDPOINT="YOUR_TESTNET_HOLESKY_ENDPOINT"
MAINNET_ENDPOINT="YOUR_ETH_MAINNET_ENDPOINT"
OPERATOR_VALIDATOR_ADDRESS=$(zenrockd keys show wallet --bech val -a)
OPERATOR_ADDRESS=$ecdsa_address
ETH_RPC_URL="YOUR_TESTNET_HOLESKY_RPC"
ETH_WS_URL="YOUR_TESTNET_HOLESKY_WS"
SOLANA_MAINNET_ENDPOINT="YOUR_SOLANA_MAINNET_ENDPOINT"
ECDSA_KEY_PATH=$ecdsa_output_file
BLS_KEY_PATH=$bls_output_file
PROXY_URL="url" 
PROXY_USER="user"
PROXY_PASSWORD="password"
