Update system and install build tools

sudo apt update && sudo apt upgrade -y
sudo apt install curl iptables build-essential git wget jq make gcc nano tmux htop nvme-cli pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev -y

Install GO

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.24.2.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)
eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Download binary files

cd $HOME
mkdir -p $HOME/.zetacored/config
cd $HOME
wget -O $HOME/zetacored https://github.com/zeta-chain/node/releases/download/v36.0.0/zetacored-linux-amd64
chmod +x $HOME/zetacored 
mv $HOME/zetacored  $HOME/go/bin

We initialize the node to create the necessary configuration files

zetacored init <YOUR_MONIKER_NAME> --chain-id athens_7001-1

Download Genesis

wget -O $HOME/.zetacored/config/genesis.json https://server-3.itrocket.net/testnet/zetachain/genesis.json

At this stage, we can download the address book

wget -O $HOME/.zetacored/config/addrbook.json  https://server-3.itrocket.net/testnet/zetachain/addrbook.json

Set up node configuration

# Set node configuration
zetacored config chain-id athens_7001-1
