echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source ~/.bash_profile
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin

Define Environment Variables:

echo "export WALLET='wallet'" >> $HOME/.bash_profile
echo "export MONIKER='noderuner'" >> $HOME/.bash_profile
echo "export ZENROCK_CHAIN_ID='gardia-2'" >> $HOME/.bash_profile
echo "export ZENROCK_PORT=46657" >> $HOME/.bash_profile  # Set custom base port here
source ~/.bash_profile

Download the Zenrockd Binary:

cd $HOME
curl -o zenrockd https://releases.gardia.zenrocklabs.io/zenrockd-latest
chmod +x zenrockd
mv zenrockd ~/go/bin/

Configure and Initialize Node:

zenrockd init $MONIKER --chain-id $ZENROCK_CHAIN_ID
zenrockd config set client chain-id $ZENROCK_CHAIN_ID
zenrockd config set client node tcp://localhost:${ZENROCK_PORT}

wget -O $HOME/.zrchain/config/genesis.json https://raw.githubusercontent.com/mytolga/zenrock/refs/heads/main/genesis.json
wget -O $HOME/.zrchain/config/addrbook.json https://raw.githubusercontent.com/mytolga/zenrock/refs/heads/main/addrbook.json

Set Seed and Peer Nodes:

SEEDS="[e-mail]:46656"
PEERS=$(curl -sS https://zenrock-testnet-rpc.noderuner.xyz/net_info | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}' | paste -sd, -)
echo $PEERS
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.zrchain/config/config.toml
