➡️ Let's get started

sudo systemctl restart emped

➡️ Create wallet

emped keys add

➡️Recover wallet

emped keys add wallet-name --recover

➡️ Faucet

Empeiria testnet faucet

➡️ Create Validator

Reminder: You can't create a validator without Sync. You must have to catch the latest block.

cd $HOME

emped tx staking create-validator \
  --amount=1000000uempe \
  --pubkey=$(emped tendermint show-validator) \
  --moniker "" \
  --chain-id=empe-testnet-2 \
  --identity "" \
  --details "" \
  --website "" \
  --commission-max-change-rate=0.01 \
  --commission-max-rate=1.0 \
  --commission-rate=0.05 \
  --min-self-delegation="1" \
  --fees=500uempe \
  --from= \
  --node=http://localhost:(whatever you typed in custom_port)57
  -y

➡️ Delegation

emped tx staking delegate  000000uempe \
--chain-id empe-testnet-2 \
--from "" \
--fees 500uempe \
--node=http://localhost:57

➡️ Complete deletion

cd $HOME
sudo systemctl stop emped
sudo systemctl disable emped
sudo rm -rf /etc/systemd/system/emped.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/emped
sudo rm -f $(which emped)
sudo rm -rf $HOME/.empe-chain
sed -i "/EMPE_/d" $HOME/.bash_profile

➡️ Block check

local_height=$(curl -s localhost:57/status | jq -r .result.sync_info.latest_block_height); network_height=$(curl -s https://empe-testnet-rpc.mictonode.com/status | jq -r .result.sync_info.latest_block_height); blocks_left=$((network_height - local_height)); echo "Your node height: $local_height"; echo "Network height: $network_height"; echo "Blocks left: $blocks_left"

Your node height - the current block of your node
Network height - the last block of the network
Blocks left - how many blocks your node has left to sync.
