🛠️Manual Installation

This guide is created under the assumption you are using Ubuntu 22.04 LTS If you use other OS, please modify the commands accordingly

Set environment

export INSTALLATION_DIR=${HOME}/empe-chain
export DAEMON_NAME=emped
export DAEMON_HOME=${HOME}/.empe-chain
export SERVICE_NAME=emped
export MONIKER="YOUR_NODE_NAME_HERE"
export WALLET="YOUR_WALLET_NAME_HERE"

DAEMON_HOME is the default path, you customize it as you wish

Write env to .profile

echo 'export DAEMON_NAME=${DAEMON_NAME}' >> ~/.profile
echo 'export DAEMON_HOME=${DAEMON_HOME}' >> ~/.profile
echo 'export DAEMON_ALLOW_DOWNLOAD_BINARIES=true' >> ~/.profile
echo 'export DAEMON_RESTART_AFTER_UPGRADE=true' >> ~/.profile
echo 'export DAEMON_LOG_BUFFER_SIZE=512' >> ~/.profile
echo 'export WALLET=${WALLET}' >> ~/.profile

source ~/.profile

This step is optional, but we recommend you to do it for convenience

Install dependencies

Please refer to Server Preparation

Prepare installation

mkdir -p ${INSTALLATION_DIR}/bin
mkdir -p ${DAEMON_HOME}/cosmovisor/genesis/bin
mkdir -p ${DAEMON_HOME}/cosmovisor/upgrades

Install and Setup Empeiria Daemon

cd ${INSTALLATION_DIR}

#Download Empe Daemon and basic setup
wget -qO - https://github.com/empe-io/empe-chain-releases/raw/master/v0.1.0/emped_linux_amd64.tar.gz | tar -xzf -
mv ${DAEMON_NAME} ${INSTALLATION_DIR}/bin

#Download and install cosmovisor
wget https://github.com/cosmos/cosmos-sdk/releases/download/cosmovisor%2Fv1.5.0/cosmovisor-v1.5.0-linux-amd64.tar.gz
tar -xvzf cosmovisor-v1.5.0-linux-amd64.tar.gz

#Copy Binaries
cp cosmovisor ${INSTALLATION_DIR}/bin/cosmovisor
cp ${INSTALLATION_DIR}/bin/${DAEMON_NAME} ${DAEMON_HOME}/cosmovisor/genesis/bin
sudo ln -s ${INSTALLATION_DIR}/bin/cosmovisor /usr/local/bin/cosmovisor -f
sudo ln -s ${DAEMON_HOME}/cosmovisor/genesis ${DAEMON_HOME}/cosmovisor/current -f
sudo ln -s ${DAEMON_HOME}/cosmovisor/current/bin/${DAEMON_NAME} /usr/local/bin/${DAEMON_NAME} -f

Check emped version

emped --home ${DAEMON_HOME} version

Download genesis.json

wget https://snapshot.cryptonode.id/empe-testnet/genesis.json -O ${DAEMON_HOME}/config/genesis.json

Create or Restore Wallet

#If you want to create new wallet
emped --home ${DAEMON_HOME} keys add ${WALLET}

#If you already have wallet and want to use same phrase
emped --home ${DAEMON_HOME} keys add ${WALLET} --recover

You will be prompted to "Enter your bip39 mnemonic", paste your phrase and press [ENTER]

Check your wallet

emped --home ${DAEMON_HOME} keys list

Setup pruning config

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "10"|' \
  ${DAEMON_HOME}/config/app.toml

The number shown only for reference. You can change the number for each parameter as you want

Setting minimum gas fee

sed -i 's/minimum-gas-prices *=.*/minimum-gas-prices = "0.0001uempe"/' ${DAEMON_HOME}/config/app.toml

Setting up Cosmovisor

sudo tee /etc/systemd/system/emped.service > /dev/null <<EOF
