Manual Install:

Server preparation

• Updating packages

sudo apt update && sudo apt upgrade -y

• Install developer tools and necessary packages

sudo apt install curl build-essential pkg-config libssl-dev git wget jq make gcc tmux chrony -y

• Installing GO

ver="1.20.3"
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
go version

Node installation

• Clone the project repository with the node, go to the project folder and collect the binary files

cd $HOME
wget https://github.com/MANTRA-Finance/public/raw/main/mantrachain-testnet/mantrachaind-linux-amd64.zip
unzip mantrachaind-linux-amd64.zip
sudo mv mantrachaind /usr/local/bin

• Checking the version

mantrachaind version
#0.2.2

• Creating Variables

MONIKER_MANTRA=type in your name
CHAIN_ID_MANTRA=mantrachain-1
PORT_MANTRA=47

• Save variables, reload .bash_profile and check variable values

echo "export MONIKER_MANTRA="${MONIKER_MANTRA}"" >> $HOME/.bash_profile
echo "export CHAIN_ID_MANTRA="${CHAIN_ID_MANTRA}"" >> $HOME/.bash_profile
echo "export PORT_MANTRA="${PORT_MANTRA}"" >> $HOME/.bash_profile
source $HOME/.bash_profile

echo -e "\nmoniker_MANTRA > ${MONIKER_MANTRA}.\n"
echo -e "\nchain_id_MANTRA > ${CHAIN_ID_MANTRA}.\n"
echo -e "\nport_MANTRA > ${PORT_MANTRA}.\n"

• Setting up the config

mantrachaind config chain-id mantrachain-1
mantrachaind config keyring-backend test
sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0uaum\"/" $HOME/.mantrachain/config/app.toml

• Initialize the node

mantrachaind init $MONIKER_MANTRA --chain-id $CHAIN_ID_MANTRA

• Loading the genesis file and address book

curl -Ls https://snapshots.revonode.xyz/mantra/genesis.json > $HOME/.mantrachain/config/genesis.json
curl -Ls https://snapshots.revonode.xyz/mantra/addrbook.json > $HOME/.mantrachain/config/addrbook.json

• Adding seeds and peers

PEERS="a435339f38ce3f973739a08afc3c3c7feb862dc5@35.192.223.187:26656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" ~/.mantrachaind/config/config.toml

• Setting up pruning

PRUNING="custom"
PRUNING_KEEP_RECENT="100"
PRUNING_INTERVAL="19"

sed -i -e "s/^pruning *=.*/pruning = \"$PRUNING\"/" $HOME/.mantrachain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \
\"$PRUNING_KEEP_RECENT\"/" $HOME/.mantrachain/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \
\"$PRUNING_INTERVAL\"/" $HOME/.mantrachain/config/app.toml
sed -i -e 's|^indexer *=.*|indexer = "null"|' $HOME/.mantrachain/config/config.toml
sed -i 's|^prometheus *=.*|prometheus = true|' $HOME/.mantrachain/config/config.toml

• Create a service file

sudo tee /etc/systemd/system/mantrachaind.service > /dev/null <<EOF
[Unit]
Description=mantrachaind testnet node
After=network-online.target
[Service]
User=$USER
ExecStart=$(which mantrachaind) start
Restart=always
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

• Start the service and check the logs

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

• We are waiting for the end of synchronization, you can check the synchronization with the command

mantrachaind status 2>&1 | jq .SyncInfo

If the output shows false, the sync is complete.

Creating a wallet and validator

• Create a wallet

mantrachaind keys add $MONIKER_MANTRA

Save the mnemonic phrase in a safe place!

If you participated in previous testnets, restore the wallet with the command and enter the mnemonic phrase

mantrachaind keys add $MONIKER_MANTRA --recover

• Create a variable with the address of the wallet and validator

WALLET_MANTRA=$(mantrachaind keys show $MONIKER_MANTRA -a)
VALOPER_MANTRA=$(mantrachaind keys show $MONIKER_MANTRA --bech val -a)

echo "export WALLET_MANTRA="${WALLET_MANTRA}"" >> $HOME/.bash_profile
echo "export VALOPER_MANTRA="${VALOPER_MANTRA}"" >> $HOME/.bash_profile
source $HOME/.bash_profile
echo -e "\nwallet_MANTRA > ${WALLET_MANTRA}.\n"
echo -e "\nvaloper_MANTRA > ${VALOPER_MANTRA}.\n"

• Checking your balance

mantrachaind q bank balances $WALLET_MANTRA

• After the synchronization is completed and the wallet is replenished, we create a validator

mantrachaind tx staking create-validator \
  --amount 1000000uself \
  --pubkey $(mantrachaind tendermint show-validator) \
  --moniker "MONIKER" \
  --identity="YOUR_KEYBASE_ID" \
  --details="YOUR_DETAILS" \
  --website="YOUR_WEBSITE_URL" \
  --chain-id self-dev-1 \
  --commission-rate="0.05" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation "1" \
  --gas-prices="0.005uself" \
  --gas="auto" \
  --gas-adjustment="1.5" \
  --from wallet \
  -y

Deleting a node

• Before deleting a node, make sure that the files from the ~/.mantrachaind/config directory are saved To remove a node, use the following commands

sudo systemctl stop mantrachaind
sudo systemctl disable mantrachaind
sudo rm -rf $HOME/.mantrachaind
sudo rm -rf /etc/systemd/system/mantrachaind.service
sudo rm -rf /usr/local/bin/mantrachaind
sudo systemctl daemon-reload
