Updating the System​

apt update && apt upgrade -y

Installing the Necessary Libraries​

apt install make clang pkg-config libssl-dev libclang-dev build-essential git curl ntp jq llvm tmux htop screen gcc lz4 -y < "/dev/null"

Installing Go​

ver="1.21.5"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
rm -rf /usr/local/go
tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm -rf "go$ver.linux-amd64.tar.gz"
echo 'export GOROOT=/usr/local/go' >> $HOME/.bash_profile
echo 'export GOPATH=$HOME/go' >> $HOME/.bash_profile
echo 'export GO111MODULE=on' >> $HOME/.bash_profile
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Setting Variables​

The areas you need to change are written below.

• $MANTRA_NODENAME your validator name

• $MANTRA_WALLET your wallet name

• If another node is using the port, you can change it below. You must enter a different value where it says 11, again as two digits.

echo "export MANTRA_NODENAME=$MANTRA_NODENAME" >> $HOME/.bash_profile
echo "export MANTRA_WALLET=$MANTRA_WALLET" >> $HOME/.bash_profile
echo "export MANTRA_PORT=11" >> $HOME/.bash_profile
echo "export MANTRA_CHAIN_ID=mantra-hongbai-1" >> $HOME/.bash_profile
source $HOME/.bash_profile

Sample​

Let's assume that your Node (MANTRA_NODENAME) and Wallet (MANTRA_WALLET) name is Anatolian-Guide and the port you will use (MANTRA_PORT) will be 16656. The code will be arranged as shown below.

echo "export MANTRA_NODENAME=Anatolian-Guide" >> $HOME/.bash_profile
echo "export MANTRA_WALLET=Anatolian-Guide" >> $HOME/.bash_profile
echo "export MANTRA_PORT=16" >> $HOME/.bash_profile
echo "export MANTRA_CHAIN_ID=mantra-hongbai-1" >> $HOME/.bash_profile
source $HOME/.bash_profile

Installing Mantra​

cd $HOME
wget -O /usr/lib/libwasmvm.x86_64.so https://github.com/CosmWasm/wasmvm/releases/download/v1.3.1/libwasmvm.x86_64.so
wget https://github.com/MANTRA-Finance/public/raw/main/mantrachain-hongbai/mantrachaind-linux-amd64.zip
unzip mantrachaind-linux-amd64.zip
rm mantrachaind-linux-amd64.zip
mv mantrachaind $HOME/go/bin
mantrachaind version

The version output will be 3.0.0.

Configuring and Launching the Node​

We copy and paste the codes below without making any changes.

Enabling the Service​

systemctl daemon-reload
systemctl enable mantrachaind

Checking the Logs​

journalctl -u mantrachaind -f -o cat

Checking Synchronization​

Unless we get a false output, we do not move on to the next step, namely creating a validator.

mantrachaind status 2>&1 | jq .SyncInfo

Wallet​

Creating a New Wallet​

mantrachaind keys add WALLET

Importing an Existing Wallet​

mantrachaind keys add WALLET --recover

Wallet and Valoper Info​

Here, wallet and valoper information are added to the variable.

MANTRA_WALLET_ADDRESS=$(mantrachaind keys show WALLET -a)
MANTRA_VALOPER_ADDRESS=$(mantrachaind keys show WALLET --bech val -a)

echo 'export MANTRA_WALLET_ADDRESS='${MANTRA_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export MANTRA_VALOPER_ADDRESS='${MANTRA_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Checking Wallet Balance​

mantrachaind query bank balances WALLET_ADDRESS

Faucet​

https://faucet.hongbai.mantrachain.io/

WARNING

If the synchronization is completed, we proceed to the following step.

Creating Validator​

mantrachaind tx staking create-validator \
--amount=1000000uom \
--pubkey=$(mantrachaind tendermint show-validator) \
--moniker=your-node-moniker \
