Section titled “Install Union Validator (testnet-9) di Ubuntu”
  1. Update paket dan install build tools
apt update
apt install curl git jq lz4 build-essential -y
apt upgrade -y

  1. Install GO
sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.22.3.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)
  1. Download binaries union
mkdir -p $HOME/.union/cosmovisor/genesis/bin
wget -O $HOME/.union/cosmovisor/genesis/bin/uniond https://snapshots.kjnodes.com/union-testnet/uniond-v0.25.0-linux-amd64
chmod +x $HOME/.union/cosmovisor/genesis/bin/uniond
ln -s $HOME/.union/cosmovisor/genesis $HOME/.union/cosmovisor/current -f
sudo ln -s $HOME/.union/cosmovisor/current/bin/uniond /usr/local/bin/uniond -f

  1. Install Cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.6.0

  1. Create service union (systemd)
sudo tee /etc/systemd/system/union-testnet.service > /dev/null << EOF
[Unit]
Description=union node service
After=network-online.target


[Service]
User=$USER
ExecStart=$(which cosmovisor) run start --home=$HOME/.union
Restart=on-failure
RestartSec=10
LimitNOFILE=65535
Environment="DAEMON_HOME=$HOME/.union"
Environment="DAEMON_NAME=uniond"
Environment="UNSAFE_SKIP_BACKUP=true"
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:$HOME/.union/cosmovisor/current/bin"


[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable union-testnet.service

  1. Inisialisasi node
  • Workaround mandatory home argument
alias uniond='uniond --home=$HOME/.union/'
  • Set node configuration
uniond config set client chain-id union-testnet-9
uniond config set client keyring-backend test
uniond config set client node tcp://localhost:17157
  • Initialize the node (ubah VALIDATOR-NAME menjadi nama validator anda)
MONIKER="VALIDATOR-NAME"
uniond init $MONIKER --chain-id union-testnet-9 --home=$HOME/.union
  • Download genesis and addrbook
curl -Ls https://raw.githubusercontent.com/CoinHuntersTR/props/refs/heads/main/union/genesis.json > $HOME/.union/config/genesis.json
curl -Ls https://raw.githubusercontent.com/CoinHuntersTR/props/refs/heads/main/union/addrbook.json > $HOME/.union/config/addrbook.json
  • Add seeds
sed -i -e "s|^seeds *=.*|seeds = \"3f472746f46493309650e5a033076689996c8881@union-testnet.rpc.kjnodes.com:17159\"|" $HOME/.union/config/config.toml
  • Set minimum gas price
sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"0muno\"|" $HOME/.union/config/app.toml
  • Set pruning
sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
  $HOME/.union/config/app.toml
  • Set custom ports
sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:17158\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:17157\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:17160\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:17156\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":17166\"%" $HOME/.union/config/config.toml
sed -i -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:17117\"%; s%^address = \":8080\"%address = \":17180\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:17190\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:17191\"%; s%:8545%:17145%; s%:8546%:17146%; s%:6065%:17165%" $HOME/.union/config/app.toml

  1. Buat key/Wallet (Simpan dan import mnemonic anda ke keplr)
uniond keys add wallet

  1. Claim faucet (konekkan wallet dan kumpulkan faucet minimal 1.2)
    app.union.build
    Add RPC union (UNO)

  2. Download latest chain snapshot

curl -L https://snapshots.coinhunterstr.com/testnet/union/snapshot_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.union
[[ -f $HOME/.union/data/upgrade-info.json ]] && cp $HOME/.union/data/upgrade-info.json $HOME/.union/cosmovisor/genesis/upgrade-info.json

  1. Start service
systemctl start union-testnet

  1. Cek logs (Jangan lanjut ke step ke 12 pastikan dulu block terbaru sama dengan yg di vps anda)
journalctl -u union-testnet.service -f --no-hostname -o cat

  1. Run Validator
  • Cek pubkey validator anda (contoh hasil {“@type”:“/cosmos.crypto.ed25519.PubKey”,“key”:“0LuMdRNJpWGiH+b+…”})
uniond comet show-validator
  • Edit yang di perlukan sebelum paste ke vps (pubkey, moniker dan website)
cat << EOF > ~/.union/config/validator.json
{
  "pubkey": {"hapus-ubah-punya-bro-@type":"/cosmos.crypto.ed25519.PubKey","key":"BCDw/cq.....zYSHfY8="},
  "amount": "1000000muno",
  "moniker": "VALIDATOR-NAME",
  "website": "https://websiteanda.com",
  "commission-rate": "0.1",
  "commission-max-rate": "0.2",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}
EOF
  • Start service lagi
systemctl start union-testnet.service
  • Export config
export PRIV_KEY=$(jq -r '.priv_key.value' ~/.union/config/priv_validator_key.json)
export POSSESSION_PROOF=$(uniond prove-possession "$PRIV_KEY")
  • Create validator
uniond union-staking create-union-validator /root/.union/config/validator.json $POSSESSION_PROOF \
  --from wallet \
  --chain-id union-testnet-9 \
  --fees 0muno

  1. Cek validator anda
    explorer.testnet-9.union.build/union/staking
