➡️ Let’s get started

sudo systemctl restart lumerad
journalctl -fu lumerad -o cat

➡️ Log Command

sudo journalctl -fu lumerad -o cat

➡️ Create wallet

Warning

Don’t forget to backup the wallet words!

lumerad keys add $LUMERA_WALLET

➡️ Import wallet

lumerad keys add $LUMERA_WALLET --recover

➡️ Faucet

Faucet 1

Faucet 2

➡️ Create Validator

Reminder

You can’t create a validator without Sync. You must have to catch the latest block.

Your node height - the current block of your node
Network height - the last block of the network
Blocks left - how many blocks your node has left to sync.
