• Update minimum-gas-price in app.toml

sed -i.bak 's/minimum-gas-prices =.*/minimum-gas-prices = "1uhuahua"/' $HOME/.chihuahuad/config/app.toml

• Setting up Cosmovisor

Install cosmovisor

go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@latest

which cosmovisor

# should return 
'/home/<your-user>/go/bin/cosmovisor'

# run these commands
cat <<EOF >> ~/.profile
export DAEMON_NAME=chihuahuad
export DAEMON_HOME=$HOME/.chihuahuad
EOF

source ~/.profile

echo $DAEMON_NAME

# should return
'chihuahuad'

# create the directories
mkdir -p $DAEMON_HOME/cosmovisor/genesis/bin
mkdir -p $DAEMON_HOME/cosmovisor/upgrades

# check the binary path with
which chihuahuad

# this should return
'/home/your-user/go/bin/chihuahuad'

# copy the binary into
cp $(which chihuahuad) $DAEMON_HOME/cosmovisor/genesis/bin

Set up the service file

sudo nano /etc/systemd/system/chihuahuad.service

# paste and edit <your-user> with your username
[Unit]
Description=Chihuahua Daemon (cosmovisor)

Get the latest snapshot (Thanks to Polkachu) and follow the Pruning tips to save some GB

• Start the node

You can start the node by running

sudo systemctl start chihuahuad

# check the logs by running
journalctl -u chihuahuad -f

The node will take some time to catch-up with the blockchain. You can follow the blocks being indexed by rnning

journalctl -u chihuahuad -f | grep indexed

Join the Validators (mainnet)

ChihuahuaChain Governance voted a proposal enabling the minimum 5% Commission enforced by the blockchain.

# create a new wallet for the validator

chihuahuad keys add <key-name>

# save the seed phrase (mnemonic) in a safe place
# copy the 'chihuahua...' address and send some HUAHUA
# in order to pay for the validator creation's transaction

# Make sure the Validator has fully synced before running 
chihuahuad tx staking create-validator \
  --from "<key-name>" \
  --amount "1000000uhuahua" \
  --pubkey "$(chihuahuad tendermint show-validator)" \
  --chain-id "chihuahua-1" \
  --moniker "<moniker>" \
  --commission-max-change-rate 0.01 \
  --commission-max-rate 0.20 \
  --commission-rate 0.10 \
  --min-self-delegation 1 \
  --details "<details>" \
  --security-contact "<contact>" \
  --website "<website>" \
  --gas-prices "1uhuahua"
  
# Make sure to backup the priv_validator_key.json file in your
# /home/<your-user>/.chihuahuad/config directory
# and store it in a safe place

Congratulation! Your Validator node should be up and running

Make sure to join our Discord and contact a moderator if you have a mainnet node so we can invite you to the validator's channel to follow up the latest updates and future upgrades.
