Manual Installation

Install binary

mkdir bin
cd bin
source ~/.profile

wget https://github.com/MANTRA-Finance/public/raw/main/mantrachain-hongbai/mantrachaind-linux-amd64.zip
unzip mantrachaind-linux-amd64.zip
rm -rf mantrachaind-linux-amd64.zip

Install cosmwasm library

More information can be found in here:

sudo wget -P /usr/lib https://github.com/CosmWasm/wasmvm/releases/download/v1.3.1/libwasmvm.x86_64.so

Initialise node

mantrachaind init <your-moniker> --chain-id mantra-hongbai-1
  • where <your-moniker>is the moniker and can be any valid string name (e.g. val-01),

  • and mantra-hongbai-1 is the Chain ID and must be exactly as specified.

Download "genesis.json" - HONGBAI

Obtain the genesis.json for the MANTRA Hongbai Chain (Testnet).

curl -Ls https://github.com/MANTRA-Finance/public/raw/main/mantrachain-hongbai/genesis.json > $HOME/.mantrachain/config/genesis.json

Update the config.toml with the seed node and the peers for the MANTRA Hongbai Chain (Testnet).

CONFIG_TOML="$HOME/.mantrachain/config/config.toml"
SEEDS="d6016af7cb20cf1905bd61468f6a61decb3fd7c0@34.72.142.50:26656"
PEERS="da061f404690c5b6b19dd85d40fefde1fecf406c@34.68.19.19:26656,20db08acbcac9b7114839e63539da2802b848982@34.72.148.3:26656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $CONFIG_TOML
sed -i.bak -e "s/^seeds =.*/seeds = \"$SEEDS\"/" $CONFIG_TOML
external_address=$(wget -qO- eth0.me)
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $CONFIG_TOML
sed -i 's|^minimum-gas-prices *=.*|minimum-gas-prices = "0.0002uom"|g' $CONFIG_TOML
sed -i 's|^prometheus *=.*|prometheus = true|' $CONFIG_TOML
sed -i -e "s/^filter_peers *=.*/filter_peers = \"true\"/" $CONFIG_TOML

Install Cosmovisor

cosmovisor is a process manager for Cosmos SDK application binaries that automates application binary switch at chain upgrades.

It polls the upgrade-info.json file that is created by the x/upgrade module at upgrade height, and then can automatically download the new binary, stop the current binary, switch from the old binary to the new one, and finally restart the node with the new binary.

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.4.0
mkdir -p ~/.mantrachain/cosmovisor/genesis/bin
mkdir -p ~/.mantrachain/cosmovisor/upgrades
cp ~/bin/mantrachaind ~/.mantrachain/cosmovisor/genesis/bin

Configure "mantrachaind" as a Service

sudo tee /etc/systemd/system/mantrachaind.service > /dev/null << EOF
[Unit]
Description=Mantra Node
After=network-online.target
[Service]
User=$USER
ExecStart=$(which cosmovisor) run start
Restart=on-failure
RestartSec=3
LimitNOFILE=10000
Environment="DAEMON_NAME=mantrachaind"
Environment="DAEMON_HOME=$HOME/.mantrachain"
Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=false"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"
Environment="UNSAFE_SKIP_BACKUP=true"
[Install]
WantedBy=multi-user.target
EOF

Starting, stoping and restarting service

#reload, enable and start
sudo systemctl daemon-reload
sudo systemctl enable mantrachaind
sudo systemctl start mantrachaind

#stop
sudo systemctl stop mantrachaind

#restart
sudo systemctl restart mantrachaind

#logs
sudo journalctl -xefu mantrachaind

#logs - filtered on block height lines
sudo journalctl -xefu mantrachaind -g ".*txindex"

Once started, the node will take some time to sync with the blockchain.

⚙️Automatic Installation

You can visit our repository and follow the instruction there

The systemd service manager allows the mantrachaind binary to run as a service, instead of as a command-line application. (See for more information.)

Visit to see the current height of the blockchain. Use the journalctl command to check on the node's progress.
