Create Wallet

create a new wallet

junctiond keys add $WALLET

restore exexuting wallet

junctiond keys add $WALLET --recover

save wallet and validator address

WALLET_ADDRESS=$(junctiond keys show $WALLET -a)
VALOPER_ADDRESS=$(junctiond keys show $WALLET --bech val -a)
echo "export WALLET_ADDRESS="$WALLET_ADDRESS >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS="$VALOPER_ADDRESS >> $HOME/.bash_profile
source $HOME/.bash_profile

check sync status

junctiond status 2>&1 | jq 

chechk balance

before creating a validator, you need to fund your wallet and check balance

junctiond query bank balances $WALLET_ADDRESS 

Create Validator

ℹ️

change all details

junctiond tx staking create-validator \
