How To Install Full Node Mantra Chain Testnet

Setting up vars

Your Nodename (validator) that will shows in explorer

NODENAME=<Your_Nodename_Moniker>

Save variables to system

echo "export NODENAME=$NODENAME" >> $HOME/.bash_profile
if [ ! $WALLET ]; then
    echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export MANTRA_CHAIN_ID=mantra-hongbai-1" >> $HOME/.bash_profile
source $HOME/.bash_profile

Update packages

sudo apt update && sudo apt upgrade -y

Install dependencies

sudo apt install curl build-essential git wget jq make gcc tmux net-tools ccze -y

Install go

if ! [ -x "$(command -v go)" ]; then
  ver="1.20.2"
  cd $HOME
  wget "https://golang.org/dl/go$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" >> ~/.bash_profile
  source ~/.bash_profile
fi

Download and build binaries

cd $HOME
wget https://snapshot3.konsortech.xyz/mantra-testnet/mantrachaind-linux-amd64.zip
unzip mantrachaind-linux-amd64.zip
rm mantrachaind-linux-amd64.zip
mv mantrachaind $HOME/go/bin/
sudo wget -P /usr/lib https://github.com/CosmWasm/wasmvm/releases/download/v1.3.1/libwasmvm.x86_64.so
mantrachaind version

Config app

mantrachaind config chain-id $MANTRA_CHAIN_ID

Init app

mantrachaind init $NODENAME --chain-id $MANTRA_CHAIN_ID

Download configuration

cd $HOME
curl -Ls https://snapshot.konsortech.xyz/mantra-testnet/genesis.json > $HOME/.mantrachain/config/genesis.json
curl -Ls https://snapshot.konsortech.xyz/mantra-testnet/addrbook.json > $HOME/.mantrachain/config/addrbook.json

Disable indexing

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

Config pruning

sed -i 's|pruning = "default"|pruning = "custom"|g' $HOME/.mantrachain/config/app.toml
sed -i 's|pruning-keep-recent = "0"|pruning-keep-recent = "100"|g' $HOME/.mantrachain/config/app.toml
sed -i 's|pruning-interval = "0"|pruning-interval = "10"|g' $HOME/.mantrachain/config/app.toml

Set minimum gas price

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

Create service

sudo tee /etc/systemd/system/mantrachaind.service > /dev/null << EOF
[Unit]
Description=Mantra Node
After=network-online.target
[Service]
User=$USER
ExecStart=$(which mantrachaind) start
Restart=on-failure
RestartSec=10
LimitNOFILE=10000
[Install]
WantedBy=multi-user.target
EOF

Register and start service

sudo systemctl daemon-reload
sudo systemctl enable mantrachaind
sudo systemctl restart mantrachaind && sudo journalctl -u mantrachaind -f -o cat

Guidence for create validator

Create wallet

To create new wallet you can use command below. Don’t forget to save the mnemonic

mantrachaind keys add $WALLET

To recover your wallet using seed phrase

mantrachaind keys add $WALLET --recover

Show your wallet list

mantrachaind keys list

Save wallet info

Add wallet and validator address into variables

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

Fund your wallet

Faucet available on website

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

Create validator

check your wallet balance:

mantrachaind query bank balances $MANTRA_WALLET_ADDRESS

To create your validator run command below

mantrachaind tx staking create-validator \
  --amount 10000000uom \
  --from $WALLET \
  --commission-max-change-rate "0.01" \
  --commission-max-rate "0.2" \
  --commission-rate "0.1" \
  --min-self-delegation "1" \
  --pubkey $(mantrachaind tendermint show-validator) \
  --moniker $NODENAME \
  --chain-id $MANTRA_CHAIN_ID
  --gas="auto" \
  --gas-adjustment 2

Check your validator key

[[ $(mantrachaind q staking validator $MANTRA_VALOPER_ADDRESS -oj | jq -r .consensus_pubkey.key) = $(mantrachaind status | jq -r .ValidatorInfo.PubKey.value) ]] && echo -e "\n\e[1m\e[32mTrue\e[0m\n" || echo -e "\n\e[1m\e[31mFalse\e[0m\n"

Get list of validators

mantrachaind q staking validators -oj --limit=3000 | jq '.validators[] | select(.status=="BOND_STATUS_BONDED")' | jq -r '(.tokens|tonumber/pow(10; 6)|floor|tostring) + " \t " + .description.moniker' | sort -gr | nl
