Wallets

# Create wallet
agd keys add wallet

The wallet has been created. In the last line there will be a phrase that must be written down

# If the wallet was already there, restore it
agd keys add wallet --recover

# Insert the seed phrase from your wallet
# If everything is correct, you will see your wallet data

Validator

Do not forget to create a profile on https://keybase.io/ and set a profile photo there that will be imported by key and used for your validators.

agd tx staking create-validator \
