💢 Start Service and Check the Logs

sudo systemctl start celestia-testnet.service && sudo journalctl -u celestia-testnet.service -f --no-hostname -o cat

💢 Set Up Validator

💢 1. Create a wallet

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

Option 1 - Create new wallet

celestia-appd keys add wallet

Option 2 - Recover existing wallet

celestia-appd 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:

celestia-appd keys list

💢 2. Fund a wallet

To create a validator you have to fund the previously created wallet via Discord by sending this message to the #mocha-faucet channel:

$request celestia1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

To check wallet balance use command below:

celestia-appd q bank balances $(celestia-appd keys show wallet -a)

💢 3. Create validator

Please make sure you have adjusted moniker, identity, details, website to match your values.

celestia-appd tx staking create-validator \
  --amount 1000000utia \
  --pubkey $(celestia-appd tendermint show-validator) \
  --moniker "YOUR_MONIKER_NAME" \
  --identity "YOUR_KEYBASE_ID" \
  --details "YOUR_DETAILS" \
  --website "YOUR_WEBSITE_URL" \
  --chain-id mocha-4 \
  --commission-rate 0.05 \
  --commission-max-rate 0.20 \
  --commission-max-change-rate 0.05 \
  --min-self-delegation 1 \
  --from wallet \
  --gas-adjustment 1.4 \
  --gas auto \
  --gas-prices 0.005utia \
  -y
