Execute the folloiwng command to get the node id

kujirad tendermint show-node-id

Create a Wallet for your Validator Node

Make sure to copy the 24 words Mnemonics Phrase, save it in a file and store it on a safe location.

kujirad keys add <wallet-name>

#Example
kujirad keys add my_wallet

The following applys after the network goes live on 13th June 2022

Get some KUJI tokens to the above created wallet.

Create and Register Your Validator Node

kujirad tx staking create-validator -y \
  --chain-id harpoon-4 \
  --moniker <moniker-name> \
  --pubkey "$(kujirad tendermint show-validator)" \
  --amount 5000000ukuji \
  --identity "<Keybase.io ID>" \
  --website "<website-address>" \
  --details "Some description" \
  --from <wallet-name> \
  --gas-prices 1ukuji \
  --commission-rate=0.0 \
  --commission-max-rate=0.05 \
  --commission-max-change-rate=0.01 \
  --min-self-delegation 1
  
#Example

kujirad tx staking create-validator -y \
  --chain-id harpoon-4 \
  --moniker "My Node" \
  --pubkey "$(kujirad tendermint show-validator)" \
  --amount 5000000ukuji \
  --identity "D74433D32938F013" \
  --website "http://www.mywebsite.com" \
  --details "Some description" \

Get Validator Operator Address (Valapor Address)

Make sure to change <wallet-name> to correct values.

kujira keys show <wallet-name> --bech val --output json | jq -r .address

#Example
kujirad keys show my_wallet --bech val --output json | jq -r .address

Delegate KUJI to Your Node

kujirad tx staking delegate <validator-address> 1000000ukuji --from <wallet-name> --fees 30000ukuji --chain-id harpoon-4 -y

#Example
kujirad tx staking delegate kujiravaloper1xesqr8vjvy34jhu027zd70ypl0nnev5esqejlw 1000000ukuji --from my_wallet --fees 30000ukuji --chain-id harpoon-4 -y

Backup Validator node file

Take a backup of the following files after you have created and registered your validator node successfully.

/home/node/.kujira/config/node_key.json
/home/node/.kujira/config/priv_validator_key.json
/home/node/.kujira/data/priv_validator_state.json

Withdraw Rewards

Make sure to change <validator-operator-address>, <wallet-name> to correct values.

kujirad tx distribution withdraw-rewards <validator-address> --from <wallet-name> --chain-id=harpoon-4 --gas auto --fees 1ukuji --gas-adjustment 1.4 -y

#Example
kujirad tx distribution withdraw-rewards kujiravaloper1xesqr8vjvy34jhu027zd70ypl0nnev5esqejlw --from synergy --chain-id=harpoon-4 --gas auto --fees 1ukuji --gas-adjustment 1.4 -y

Check Balance of an Address

kujirad query bank balances <wallet-address>

#Example:
kujirad query bank balances kujira1xesqr8vjvy34jhu027zd70ypl0nnev5eh42prp
