Create Service File

sudo tee /etc/systemd/system/zenrockd.service > /dev/null <<EOF
[Unit]
Description=zenrockd Node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.zrchain

EOF

---

Start Service

sudo systemctl daemon-reload
sudo systemctl enable zenrockd
sudo systemctl restart zenrockd && sudo journalctl -u zenrockd -fo cat

---

Node Synchronize Checker

# Paste this to your terminal
bash <(curl -s https://raw.githubusercontent.com/kyronode/all-about-cosmos/refs/heads/main/Mainnet/Zenrock/zenrock-sync.sh)

---

Create or Restore Wallet

Create new wallet and save ur mnemonics securely

zenrockd keys add $WALLET

If u want to restore use this command

zenrockd keys add $WALLET --recover

Set keys variable enviroment

WALLET_ADDRESS=$(zenrockd keys show $WALLET -a)
VALOPER_ADDRESS=$(zenrockd keys show $WALLET --bech val -a)
echo "export WALLET_ADDRESS="$WALLET_ADDRESS >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS="$VALOPER_ADDRESS >> $HOME/.bash_profile
source $HOME/.bash_profile

---

Create Validator

If ur node has been fully synchronized, then u can create ur validator: Please Change <YOUR_MONIKER><YOUR_IDENTITY><YOUR_WEBSITE><YOUR_DETAILS> with ur own.

cd $HOME
echo "{
  \"pubkey\": {\"@type\": \"/cosmos.crypto.ed25519.PubKey\", \"key\": \"$(zenrockd tendermint show-validator | grep -Po '\"key\":\s*\"\K[^\"]*')\"},
  \"amount\": \"1000000urock\",
  \"moniker\": \"<YOUR_MONIKER>\",
  \"identity\": \"<YOUR_IDENTITY>\",
  \"website\": \"<YOUR_WEBSITE>\",
  \"security\": \"\",
  \"details\": \"<YOUR_DETAILS>\",
  \"commission-rate\": \"0.05\",
  \"commission-max-rate\": \"0.25\",
  \"commission-max-change-rate\": \"0.01\",
  \"min-self-delegation\": \"1\"
}" > validator.json

# Create a validator using the JSON configuration
zenrockd tx staking create-validator validator.json \
--from $WALLET \
--chain-id diamond-1 \
--gas auto \
--gas-adjustment 1.5 \
--fees 30urock \
-y
