Set up validator

Official documentation https://docs.celestia.org/nodes/validator-node

1. Create a wallet

celestia-appd keys add wallet

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. Top up wallet with tokens

You can buy tokens at https://app.osmosis.zone

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 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--gas-prices 0.005utia

Save the ~/.celestia-app/config/priv_validator_key.json file as this is the only way to recover your validator signing key in case you lose it!

Install Bridge Node

make cel-key
make install-key

which cel-key

Add Bridge wallet

Generate new wallet

cel-key add bridge-wallet --node.type bridge --p2p.network mocha

Recover existing wallet

cel-key add bridge-wallet --node.type bridge --p2p.network mocha --recover

Fund the wallet with testnet tokens

Once you start the Bridge Node, a wallet key will be generated for you. You will need to fund that address

Initialize Bridge node

celestia bridge init \
  --keyring.accname bridge-wallet \
  --core.ip http://localhost \
  --p2p.network mocha

Create service
