Create emped service for your node to run in the background

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

[Service]
User=$USER
ExecStart=$(which emped) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Start node

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

Check for your syncing progress

emped status 2>&1 | jq .SyncInfo

Create wallet

emped keys add $WALLET_NAME

# DO NOT FORGET TO SAVE THE SEED PHRASE & YOUR PASSPHRASE YOU SET FOR THIS WALLET
# You can add --recover flag to restore existing key instead of creating

Create validator

emped tx staking create-validator \
--amount=79000000uempe \
--moniker="" \
--identity="" \
--details="" \
--website="" \
--pubkey=$(emped tendermint show-validator) \
--chain-id=empe-testnet-2 \
--commission-rate="0.10" \
--commission-max-rate="0.20" \
--commission-max-change-rate="0.01" \
--min-self-delegation="1000000" \
--from=wallet \
--fees=20000uempe \
-y

Check Balances:

emped q bank balances $(emped keys show wallet -a)

View Validator details:

emped q staking validator $(emped keys show "wallet" --bech val -a)

Unjail:

emped  tx slashing unjail --from wallet --chain-id empe-testnet-2 --gas=auto --fees=20000uempe -y

Send token to another wallet:

emped tx bank send wallet <TO_WALLET_ADDRESS> 1000000uempe --from wallet --chain-id empe-testnet-2 --fees=20000uempe -y

Delegate tokens to yourself:

emped tx staking delegate $(emped keys show wallet --bech val -a) 10000000uempe --from wallet --chain-id empe-testnet-2 --fees=20000uempe -y

Congratulation!!
