Hardware Requirements

⚠️ Disk usage grows over time. Plan for long-term storage growth if running an archival node.

---

Network Endpoints

---

Step 1 — System Verification

After SSH-ing into your server, verify the system meets requirements:

lsb_release -a          # Should be Ubuntu 22.04 or higher
uname -r                # Kernel version
lscpu | grep -E "Model name|CPU\(s\)|Thread|Socket|Core"
free -h                 # Minimum 16 GB RAM
df -h                   # Minimum 500 GB free disk

---

Step 2 — System Update and Dependencies

sudo apt update && sudo apt upgrade -y
sudo apt install -y curl git wget htop tmux build-essential jq make lz4 gcc unzip

---

Step 3 — Install Go

MANTRA Chain v8.1.0 requires Go 1.23+:

cd $HOME
VER="1.23.0"
wget "https://golang.org/dl/go$VER.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$VER.linux-amd64.tar.gz"
rm "go$VER.linux-amd64.tar.gz"

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

Verify the installation:

go version

Expected output: go version go1.23.0 linux/amd64

---

Step 4 — Download Binary

mkdir -p $HOME/.mantrachain/cosmovisor/genesis/bin

wget -O /tmp/mantrachaind.tar.gz \
  https://github.com/MANTRA-Chain/mantrachain/releases/download/v8.1.0/mantrachaind-8.1.0-linux-amd64.tar.gz

tar -xzf /tmp/mantrachaind.tar.gz -C $HOME/.mantrachain/cosmovisor/genesis/bin/
chmod +x $HOME/.mantrachain/cosmovisor/genesis/bin/mantrachaind
rm /tmp/mantrachaind.tar.gz

ln -s $HOME/.mantrachain/cosmovisor/genesis $HOME/.mantrachain/cosmovisor/current -f
sudo ln -s $HOME/.mantrachain/cosmovisor/current/bin/mantrachaind /usr/local/bin/mantrachaind -f

Verify:

mantrachaind version

Expected output: v8.1.0

Alternatively, build from source:

git clone https://github.com/MANTRA-Chain/mantrachain
cd mantrachain && git checkout v8.1.0
make install
mkdir -p $HOME/.mantrachain/cosmovisor/genesis/bin
cp $(which mantrachaind) $HOME/.mantrachain/cosmovisor/genesis/bin/
ln -s $HOME/.mantrachain/cosmovisor/genesis $HOME/.mantrachain/cosmovisor/current -f
sudo ln -s $HOME/.mantrachain/cosmovisor/current/bin/mantrachaind /usr/local/bin/mantrachaind -f

---

Step 5 — Install Cosmovisor

go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]

Verify:

cosmovisor version

---

Step 6 — Create Systemd Service

Set your moniker and port prefix before creating the service:

MONIKER="YOUR_MONIKER"
PORT="26"   # Default is 26. Change to avoid conflicts (e.g. 27, 28...)

Create the service file:

sudo tee /etc/systemd/system/mantrachaind.service > /dev/null << EOF
[Unit]
Description=MANTRA Chain Node Service
After=network-online.target

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

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable mantrachaind

---

Step 7 — Initialize the Node

mantrachaind config set client chain-id mantra-dukong-1
mantrachaind config set client keyring-backend test
mantrachaind config set client node tcp://localhost:${PORT}657

mantrachaind init $MONIKER --chain-id mantra-dukong-1

Set environment variables permanently:

echo "export MONIKER=$MONIKER" >> $HOME/.bash_profile
echo "export MANTRA_CHAIN_ID=\"mantra-dukong-1\"" >> $HOME/.bash_profile
echo "export MANTRA_PORT=$PORT" >> $HOME/.bash_profile
source $HOME/.bash_profile

---

Step 8 — Download Genesis and Addrbook

wget -O $HOME/.mantrachain/config/genesis.json \
  https://raw.githubusercontent.com/hazennetworksolutions/mantra-dukong/refs/heads/main/genesis.json

wget -O $HOME/.mantrachain/config/addrbook.json \
  https://raw.githubusercontent.com/hazennetworksolutions/mantra-dukong/refs/heads/main/addrbook.json

Verify genesis checksum:

sha256sum $HOME/.mantrachain/config/genesis.json

---

Step 9 — Configure Ports, Gas Prices and Pruning

Custom Ports

If you changed the default port prefix, apply it here:

sed -i.bak -e "s%:1317%:${MANTRA_PORT}317%g;
s%:8080%:${MANTRA_PORT}080%g;
s%:9090%:${MANTRA_PORT}090%g;
s%:9091%:${MANTRA_PORT}091%g;
s%:8545%:${MANTRA_PORT}545%g;
s%:8546%:${MANTRA_PORT}546%g" $HOME/.mantrachain/config/app.toml

sed -i.bak -e "s%:26658%:${MANTRA_PORT}658%g;
s%:26657%:${MANTRA_PORT}657%g;
s%:6060%:${MANTRA_PORT}060%g;
s%:26656%:${MANTRA_PORT}656%g;
s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${MANTRA_PORT}656\"%;
s%:26660%:${MANTRA_PORT}660%g" $HOME/.mantrachain/config/config.toml

Gas Prices

sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "0.0002uom"|g' \
  $HOME/.mantrachain/config/app.toml

Pruning

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.mantrachain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.mantrachain/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"19\"/" $HOME/.mantrachain/config/app.toml

Enable Prometheus (optional)

sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.mantrachain/config/config.toml

Disable Indexer (saves disk space)

sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.mantrachain/config/config.toml

---

Step 10 — Configure Seeds and Peers

SEEDS="a9a71700397ce950a9396421877196ac19e7cde0@mantra-testnet-seed.itrocket.net:22656"
PEERS="1a46b1db53d1ff3dbec56ec93269f6a0d15faeb4@mantra-testnet-peer.itrocket.net:22656,[email protected]:36656,[email protected]:26667,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656"

sed -i -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*seeds *=.*/seeds = \"$SEEDS\"/}" \
       -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*persistent_peers *=.*/persistent_peers = \"$PEERS\"/}" \
       $HOME/.mantrachain/config/config.toml

---

Step 11 — Start the Node

sudo systemctl start mantrachaind
sudo journalctl -u mantrachaind -f --no-pager -o cat

Verify the service is running:

sudo systemctl status mantrachaind --no-pager

The service should show active (running).

Check sync status:

mantrachaind status 2>&1 | jq .SyncInfo

Wait until catching_up is false before proceeding to validator registration.

---

Step 12 — Create a Wallet

mantrachaind keys add wallet --keyring-backend test

⚠️ CRITICAL: Save your mnemonic phrase in a secure location. Without it, you cannot recover your wallet.

To recover an existing wallet:

mantrachaind keys add wallet --recover --keyring-backend test

Get testnet tokens from the faucet:

🚰 Faucet: faucet.dukong.mantrachain.io

Check your balance:

mantrachaind query bank balances $(mantrachaind keys show wallet -a --keyring-backend test)

---

Step 13 — Register as a Validator

The node must be fully synced before creating a validator.

Get your pubkey:

mantrachaind comet show-validator

Create validator JSON:

cat > $HOME/validator.json << EOF
{
  "pubkey": $(mantrachaind comet show-validator),
  "amount": "1000000uom",
  "moniker": "YOUR_MONIKER",
  "identity": "",
  "website": "",
  "security": "",
  "details": "",
  "commission-rate": "0.05",
  "commission-max-rate": "0.20",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}
EOF

Submit the transaction:

mantrachaind tx staking create-validator $HOME/validator.json \
  --from wallet \
  --chain-id mantra-dukong-1 \
  --keyring-backend test \
  --gas auto \
  --gas-adjustment 1.4 \
  --fees 500uom \
  -y

Verify your validator:

mantrachaind query staking validator \
  $(mantrachaind keys show wallet --bech val -a --keyring-backend test)

---

Monitoring the Node

Watch live block commits:

sudo journalctl -u mantrachaind -f --no-pager | grep "committed block"

Full logs:

sudo journalctl -u mantrachaind -f --no-pager

Sync status:

mantrachaind status 2>&1 | jq .SyncInfo

Service management:

# Restart service
sudo systemctl restart mantrachaind

# Stop service
sudo systemctl stop mantrachaind

# Check status
sudo systemctl status mantrachaind

---

Staying Updated

Follow these channels to stay informed about upgrades and announcements:

• Discord: MANTRA Chain Discord
• GitHub Releases: MANTRA-Chain/mantrachain Releases
• Official Docs: docs.mantrachain.io

Upgrade with Cosmovisor (example: v9.0.0)

mkdir -p $HOME/.mantrachain/cosmovisor/upgrades/v9.0.0/bin

wget -O /tmp/mantrachaind.tar.gz \
  https://github.com/MANTRA-Chain/mantrachain/releases/download/v9.0.0/mantrachaind-9.0.0-linux-amd64.tar.gz

tar -xzf /tmp/mantrachaind.tar.gz -C $HOME/.mantrachain/cosmovisor/upgrades/v9.0.0/bin/
