Validator setup

To set up a validator, follow the steps below. Official validator setup instructions can be found at https://github.com/zenrocklabs/zenrock-validators.

Step 1: Create a wallet

First of all we will need to create wallet for our validator. You have two options for that.

Option 1 - Create new wallet

zenrockd keys add wallet

Option 2 - Recover existing wallet

zenrockd keys add wallet --recover

Save the mnemonic output as this is the only way to recover your validator wallet in case you lose it!

To list your wallets use command below

zenrockd keys list

Step 2: Fund a wallet

To create validator you have to top up previously created wallet with tokens.

To check wallet balance use command below

zenrockd q bank balances $(zenrockd keys show wallet -a)

Step 3: Create validator

Ensure that you have updated the validator details to match your own.

zenrockd tx validation create-validator <(cat <<EOF
{
  "pubkey": $(zenrockd comet show-validator),
  "amount": "1000000urock",
  "moniker": "YOUR_MONIKER_NAME",
  "identity": "YOUR_KEYBASE_ID",
  "website": "YOUR_WEBSITE_URL",
  "security": "YOUR_SECURITY_EMAIL",
  "details": "YOUR_DETAILS",
  "commission-rate": "0.05",
  "commission-max-rate": "0.20",
  "commission-max-change-rate": "0.05",
  "min-self-delegation": "1"
}
EOF
) \
--chain-id diamond-1 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--gas-prices 2.5urock \
-y

Save the $HOME/.zrchain/config/priv_validator_key.json file as this is the only way to recover your validator signing key in case you lose it!
