Wallets

# Create wallet
lavad 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
lavad keys add wallet --recover

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