⛓️Sidecar setup (Oracle)

credit: kjnodes

➡️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"

➡️Top up your wallet address

Please fund your wallet addresses with Holesky $ETH before proceeding further. https://cloud.google.com/application/web3/faucet/ethereum/holesky

➡️Set operator configuration

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

➡️Declare variables

EIGEN_OPERATOR_CONFIG="$HOME/.zrchain/sidecar/eigen_operator_config.yaml"
TESTNET_HOLESKY_ENDPOINT="YOUR_TESTNET_HOLESKY_ENDPOINT"
MAINNET_ENDPOINT="YOUR_ETH_MAINNET_ENDPOINT"
OPERATOR_VALIDATOR_ADDRESS_TBD=$(zenrockd keys show wallet --bech val -a)
OPERATOR_ADDRESS_TBU=$ecdsa_address
ETH_RPC_URL="YOUR_TESTNET_HOLESKY_RPC"
ETH_WS_URL="YOUR_TESTNET_HOLESKY_WS"
ECDSA_KEY_PATH=$ecdsa_output_file
BLS_KEY_PATH=$bls_output_file

➡️Copy initial configuration files

cp $HOME/zenrock-validators/configs/eigen_operator_config.yaml $HOME/.zrchain/sidecar/
cp $HOME/zenrock-validators/configs/config.yaml $HOME/.zrchain/sidecar/

➡️Replace variables in config.yaml

sed -i "s|EIGEN_OPERATOR_CONFIG|$EIGEN_OPERATOR_CONFIG|g" "$HOME/.zrchain/sidecar/config.yaml"
sed -i "s|TESTNET_HOLESKY_ENDPOINT|$TESTNET_HOLESKY_ENDPOINT|g" "$HOME/.zrchain/sidecar/config.yaml"
sed -i "s|MAINNET_ENDPOINT|$MAINNET_ENDPOINT|g" "$HOME/.zrchain/sidecar/config.yaml"

➡️Replace variables in eigen_operator_config.yaml

sed -i "s|OPERATOR_VALIDATOR_ADDRESS_TBD|$OPERATOR_VALIDATOR_ADDRESS_TBD|g" "$HOME/.zrchain/sidecar/eigen_operator_config.yaml"
sed -i "s|OPERATOR_ADDRESS_TBU|$OPERATOR_ADDRESS_TBU|g" "$HOME/.zrchain/sidecar/eigen_operator_config.yaml"
sed -i "s|ETH_RPC_URL|$ETH_RPC_URL|g" "$HOME/.zrchain/sidecar/eigen_operator_config.yaml"
sed -i "s|ETH_WS_URL|$ETH_WS_URL|g" "$HOME/.zrchain/sidecar/eigen_operator_config.yaml"
sed -i "s|ECDSA_KEY_PATH|$ECDSA_KEY_PATH|g" "$HOME/.zrchain/sidecar/eigen_operator_config.yaml"
sed -i "s|BLS_KEY_PATH|$BLS_KEY_PATH|g" "$HOME/.zrchain/sidecar/eigen_operator_config.yaml"

➡️Download sidecar binary

wget -O $HOME/.zrchain/sidecar/bin/validator_sidecar https://releases.gardia.zenrocklabs.io/validator_sidecar-1.2.3
chmod +x $HOME/.zrchain/sidecar/bin/validator_sidecar

➡️Create and run sidecar service

➡️Create Service
