Create Service File

sudo tee /etc/systemd/system/emped.service > /dev/null <<EOF
[Unit]
Description=emped Node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.empe-chain

EOF

---

Start Service

sudo systemctl daemon-reload
sudo systemctl enable emped
sudo systemctl restart emped && sudo journalctl -u emped -fo cat

Node Synchronize Checker

# Paste this to your terminal
bash <(curl -s https://raw.githubusercontent.com/kyronode/all-about-cosmos/refs/heads/main/Testnet/Empe/empe-sync.sh)

---

Create or Restore Wallet

Create new wallet and save ur mnemonics securely

emped keys add $WALLET

If u want to restore use this command

emped keys add $WALLET --recover

Set keys variable enviroment

WALLET_ADDRESS=$(emped keys show $WALLET -a)
VALOPER_ADDRESS=$(emped 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

If ur node has been fully synchronized, then u can create ur validator: Please Change <YOUR_MONIKER><YOUR_IDENTITY><YOUR_WEBSITE><YOUR_DETAILS> with ur own.

emped tx staking create-validator \
--amount 1000000uempe \
--from $WALLET \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(emped tendermint show-validator) \
--moniker "<YOUR_MONIKER>" \
--identity "<YOUR_IDENTITY>" \
--website "<YOUR_WEBSITE>" \
--details "<YOUR_DETAILS>" \
--chain-id empe-testnet-2 \
--gas auto --gas-adjustment 1.5 --fees 30uempe \
-y
