Validator :

Crate Wallet :

zenrockd keys add wallet

If you Want Recover Wallet :

zenrockd keys add wallet --recover

Save the mnemonic output as this is the only way to recover your validator wallet in case you lose it!

Fund a wallet - Faucet :

https://gardia.zenrocklabs.io/workspacesgardia.zenrocklabs.io

Check Wallet Balance :

zenrockd q bank balances $(zenrockd keys show wallet -a)

Create validator

zenrockd tx validation create-validator <(cat <<EOF
