➡️ Let’s get started

sudo systemctl restart 0gchaind
journalctl -fu 0gchaind -o cat

➡️ Create wallet

0gchaind keys add wallet-name --eth

➡️ Import wallet

0gchaind keys add wallet-name --eth --recover

➡️ Import private key

0gchaind keys unsafe-export-eth-key wallet-name

➡️ Faucet

Faucet

➡️ Create Validator

cd $HOME

0gchaind tx staking create-validator \
  --amount=1000000ua0gi \
  --pubkey=$(0gchaind tendermint show-validator) \
  --moniker=MONIKER-YAZ \
  --chain-id=zgtendermint_16600-2 \
  --commission-rate=0.05 \
  --commission-max-rate=0.10 \
  --commission-max-change-rate=0.01 \
  --min-self-delegation=1 \
  --from=wallet-name \
  --identity="" \
  --website="" \
  --details="" \
  --node=http://localhost:${OG_PORT}657 \
  -y

➡️ Delegation

0gchaind tx staking delegate $(0gchaind keys show wallet-name --bech val -a)  ammount000000ua0gi --from wallet-name --node=http://localhost:${OG_PORT}657 -y

➡️ Complete deletion

cd $HOME
sudo systemctl stop 0gchaind
sudo systemctl disable 0gchaind
sudo rm -rf /etc/systemd/system/0gchaind.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/0gchaind
sudo rm -f $(which 0gchaind)
sudo rm -rf $HOME/.0gchain
sed -i "/OG_PORT_/d" $HOME/.bash_profile

➡️ Block check

local_height=$(curl -s localhost:${OG_PORT}657/status | jq -r .result.sync_info.latest_block_height); network_height=$(curl -s https://0g-testnet-rpc.mictonode.com/status | jq -r .result.sync_info.latest_block_height); blocks_left=$((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.
