➡️ Create wallet
Warning
don’t forget to backup the wallet words!
titand keys add wallet-name
➡️ Import wallet
titand keys add wallet-name --recover
➡️ Faucet
➡️ 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.
