    else
  echo no have snap
fi

➡️ Let's get started

sudo systemctl restart zenrockd

➡️ Create wallet

zenrockd keys add

➡️ Import wallet

zenrockd keys add  --recover

➡️ Faucet

$request [chain ID] [zenrock address]

Zenrock Portal

➡️ Wallet Address

zenrockd keys show  -a

➡️ Valoper Address

zenrockd keys show  --bech val -a

➡️ Block check

if “Blocks Left” is 0, it is sync

local_height=$(curl -s localhost:${ZENROCK_PORT}657/status | jq -r .result.sync_info.latest_block_height); network_height=$(curl -s https://zenrock-testnet-rpc.mictonode.com/status | jq -r .result.sync_info.latest_block_height); blocks_left=$((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
Blocks left - how many blocks your node has left to sync.
Network height - the last block of the network

➡️ Create Validator

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

cd $HOME

echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(zenrockd comet show-validator | grep -Po '\"key\":\s*\"\K[^"]*')\"},
    \"amount\": \"1000000urock\",
    \"moniker\": \"MictoNode\",
    \"identity\": \"\",
    \"website\": \"\",
    \"security\": \"\",
    \"details\": \"Life is beautiful with Web3\",
    \"commission-rate\": \"0.05\",
    \"commission-max-rate\": \"0.2\",
    \"commission-max-change-rate\": \"0.01\",
    \"min-self-delegation\": \"1\"
}" > validator.json

zenrockd tx validation create-validator validator.json \
    --from  \
    --chain-id gardia-2 \
    --fees 30urock

➡️ Delegation

zenrockd tx validation delegate $(zenrockd keys show  --bech val -a) 000000urock \
--chain-id gardia-2 \
--from "" \
--fees 30urock

➡️ Complete deletion

cd $HOME
sudo systemctl stop zenrockd
sudo systemctl disable zenrockd
sudo rm -rf /etc/systemd/system/zenrockd.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/zenrockd
sudo rm -f $(which zenrockd)
sudo rm -rf $HOME/.zrchain
