1. Join the network

namadac utils join-network --chain-id $CHAIN_ID --add-persistent-peers

Expected output:

Downloading config release from https://github.com/vknowable/namada-campfire/releases/download/housefire-alpaca/housefire-alpaca.cc0d3e0c033be.tar.gz ... Successfully configured for chain ID housefire-alpaca.cc0d3e0c033be

1. Verify Configuration Files

ls /root/.local/share/namada/housefire-alpaca.cc0d3e0c033be

1. Download WASM Files

wget -O - https://testnet.housefire.tududes.com/wasm.tar.gz | tar -xz -C $HOME/.local/share/namada/housefire-alpaca.cc0d3e0c033be/wasm/ --strip-components=1

1. Add Seed to config.toml

sed -i 's#seeds = ".*"#seeds = "tcp://[e-mail]:26656"#' $HOME/.local/share/namada/housefire-alpaca.cc0d3e0c033be/config.toml

1. Test start node

CMT_LOG_LEVEL=p2p:none,pex:error namada node ledger run

1. Verify Executable Location

which namada #should return /usr/local/bin/namada

1. Create Systemd Service

sudo tee /etc/systemd/system/namadad.service > /dev/null <<EOF
[Unit]
Description=namada
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.local/share/namada

1. Check Node Status

• Use snapshots for fast sync: Snapshot_1 or Snapshot_2

curl localhost:26657/status | jq 

✅ Wallet & Faucet

1. Add Your Wallet

namadaw add --alias $ALIAS

1. Use one of the Faucets

• Faucet_1: Click here

• Faucet_2: Click here

1. Check balance

namada client balance --owner $ALIAS --token NAM

✅ Initialize Validator:

1. Create Validator

namada client init-validator \
