Once started, the node will take some time to sync with the blockchain.
Visit https://explorer.testnet.mantrachain.io/mantrachain to see the current height of the blockchain. Use the journalctl command to check on the node's progress.
convert node into a validator
You can, either, create a new account or import an existing account.
create keys
Create a key file.
Copy mantrachaind config keyring-backend file Generate a new public key with mnemonic phrase.
Copy mantrachaind keys add <your-moniker-keys> where <your-moniker-keys>is the moniker and can be any valid string name (e.g. validator01-keys)
The above command will produce output like this:
Copy - address: mantra1q55nrzygas0nespfu8mwt2yntq8gxll3kyug82
name: validator01-keys
pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"A/YebpAX8AqUNcNXcqIy53fJo8BGFCSaQA5A0XQWMlCG"}'
type: local
**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.
expect kid unfair uniform calm debris meadow despair vintage arrive walnut vast upset cart step funny truth vault naive note capable spray shine human KEEP THE MNEMONIC PHRASE IN A SAFE PLACE!
import keys
Alternatively, if you already have an existing mnemonic that you'd like to use, then run the following:
Copy $ mantrachaind keys add <your-moniker-keys> --recover faucet
https://faucet.testnet.mantrachain.io/
1 IP address can get 1uaum every 24 hours. In case you need to transfer uaum tokens between wallets, follow this command
Copy mantrachaind tx bank send sender_address receiver_address amount_to_send --gas="auto" --gas-adjustment 2 --gas-prices="0.0001uaum" -y Replace sender_address receiver_address amount_to_send with your values
execute "create-validator" transaction
You can create new validator from the public key of your node with the following command:
Copy mantrachaind tx staking create-validator \
--amount=1000000uaum \
--pubkey=$(mantrachaind tendermint show-validator) \
--moniker=<MONIKER> \
--chain-id=mantrachain-testnet-1 \
