"catching_up": false means that the node is synchronized, we are waiting for complete synchronization

Wallet

# Create wallet
lavad keys add wallet

Create a password for the wallet and write it down so you don't forget it. 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
lavad keys add wallet --recover
# Insert the seed phrase from your wallet
# If everything is correct, you will see your wallet data

Go to the # faucet branch and request tokens

# Save the wallet address
# Replace <your_address> with your wallet address
WALLET_LAVA=<your_address>
echo "export WALLET_LAVA="${WALLET_LAVA}"" >> $HOME/.bash_profile
source $HOME/.bash_profile

# Check balance
lavad q bank balances $WALLET_LAVA

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.

lavad tx staking create-validator \
--amount 9000000ulava \
--from=wallet \
--commission-rate "0.07" \
--commission-max-rate "0.20" \
--commission-max-change-rate "0.1" \
--min-self-delegation "1" \
--pubkey=$(lavad tendermint show-validator) \
--moniker=$MONIKER_LAVA \
--chain-id=$CHAIN_ID_LAVA \
--fees=10000ulava \
--identity=<identity> \
--details="" \
--website="" \

Check yourself in the list explorer

Or by command

lavad query staking validators --limit 1000000 -o json | jq '.validators[] | select(.description.moniker=="<name_moniker>")' | jq

# Edit the validator
lavad tx staking edit-validator \
