Reset chain data

quasarnoded tendermint unsafe-reset-all --home $HOME/.quasarnode

Create Service file

sudo tee /etc/systemd/system/quasarnoded.service > /dev/null <<EOF
[Unit]
Description=quasar
After=network-online.target

[Service]
User=$USER
ExecStart=$(which quasarnoded) start --home $HOME/.quasarnode
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Enable and start service

sudo systemctl daemon-reload
sudo systemctl enable quasarnoded
sudo systemctl restart quasarnoded && sudo journalctl -u quasarnoded -f

Snapshot, State Sync (OPTIONAL)

In order not to wait for a long synchronization, you can use our guides:

https://itrocket.net/services/testnet/quasar/#snap
https://itrocket.net/services/testnet/quasar/#sync

Create wallet

To create a new wallet, use the following command. don’t forget to save the mnemonic

quasarnoded keys add $WALLET

(optional) To restore exexuting wallet, use the following command

quasarnoded keys add $WALLET --recover

Save wallet and validator address

WALLET_ADDRESS=$(quasarnoded keys show $WALLET -a)
VALOPER_ADDRESS=$(quasarnoded keys show $WALLET --bech val -a)
echo "export WALLET_ADDRESS="${WALLET_ADDRESS} >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS="${VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Create validator

before creating a validator, you need to check the balance and make sure that the node is synched

Check Sync status, once your node is fully synced, the output from above will say false

quasarnoded status 2>&1 | jq .SyncInfo

Check your balance

quasarnoded query bank balances $WALLET_ADDRESS

Create validator

quasarnoded tx staking create-validator \
  --amount 1000000uqsr \
  --from $WALLET \
  --commission-max-change-rate "0.01" \
  --commission-max-rate "0.2" \
  --commission-rate "0.05" \
  --min-self-delegation "1" \
  --pubkey  $(quasarnoded tendermint show-validator) \
  --moniker $MONIKER \
  --chain-id $QUASAR_CHAIN_ID

Monitoring

If you want to have set up a monitoring and alert system use our cosmos nodes monitoring guide with tenderduty

Security

To protect you keys please don`t share your privkey, mnemonic and follow a basic security rules

Set up ssh keys for authentication

You can use this guide to configure ssh authentication and disable password authentication on your server
