s%:9090%:${FIAMMA_PORT}090%g;
s%:9091%:${FIAMMA_PORT}091%g;
s%:8545%:${FIAMMA_PORT}545%g;
s%:8546%:${FIAMMA_PORT}546%g;
s%:6065%:${FIAMMA_PORT}065%g" $HOME/.fiamma/config/app.toml

s%:26657%:${FIAMMA_PORT}657%g;
s%:6060%:${FIAMMA_PORT}060%g;
s%:26656%:${FIAMMA_PORT}656%g;
s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${FIAMMA_PORT}656\"%;
s%:26660%:${FIAMMA_PORT}660%g" $HOME/.fiamma/config/config.toml

9. Port, pruning, gas price, indexer (at once):

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.fiamma/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.fiamma/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"50\"/" $HOME/.fiamma/config/app.toml

sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "0.00001ufia"|g' $HOME/.fiamma/config/app.toml
sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.fiamma/config/config.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.fiamma/config/config.toml

10. Create service file (at once):// Some code

sudo tee /etc/systemd/system/fiammad.service > /dev/null <<EOF
[Unit]
Description=Fiamma node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.fiamma
ExecStart=$(which fiammad) start --home $HOME/.fiamma
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

11. Reset and Download snapshot

Latest snapshot: Block 486358

cd $HOME
rm -f fiamma_snapshot.lz4

fiammad tendermint unsafe-reset-all --home $HOME/.fiamma
if curl -s --head https://vps4.josephtran.xyz/fiamma/fiamma_snapshot.lz4 | head -n 1 | grep "200" > /dev/null; then
  echo "Snapshot found, downloading..."
  aria2c -x5 -s4 https://vps4.josephtran.xyz/fiamma/fiamma_snapshot.lz4 -o fiamma_snapshot.lz4
  if [ $? -eq 0 ]; then
    echo "Download complete, extracting..."
    lz4 -dc fiamma_snapshot.lz4 | tar -xf - -C $HOME/.fiamma
    if [ $? -eq 0 ]; then
      echo "Snapshot downloaded and extracted successfully."
    else
      echo "Failed to extract snapshot."
    fi
  else
    echo "Failed to download snapshot."
  fi
else
  echo "No snapshot found."
fi

12. Service execution:

sudo systemctl daemon-reload
sudo systemctl enable fiammad
sudo systemctl restart fiammad && sudo journalctl -u fiammad -f

*You will have to wait a while until it syncs

13. Check Latest Block Height:

fiammad status | jq '{ latest_block_height: .sync_info.latest_block_height, catching_up: .sync_info.catching_up }'

You can see your node's latsest_block_height like below (Or you can check catching_up is false) If the block height is set, you can create validator.

# Block sync left:

while true; do 
  local_height=$(fiammad status | jq -r .sync_info.latest_block_height); 
  network_height=$(curl -s https://testnet-rpc.fiammachain.io/status | jq -r '.result.sync_info.latest_block_height')
  blocks_left=$((network_height - local_height)); 

  echo -e "\033[1;38mYour node height:\033[0m \033[1;34m$local_height\033[0m | \033[1;35mNetwork height:\033[0m \033[1;36m$network_height\033[0m | \033[1;29mBlocks left:\033[0m \033[1;31m$blocks_left\033[0m"; 
  sleep 5; 
done

14. Wallet config, check EVM address:

Add new wallet:

fiammad keys add "wallet_name" --eth

Or recover by seed phrase

fiammad keys add "wallet_name" --eth --recover

*Replace your "wallet_name"

15. Faucet token:

Faucet link: https://testnet-faucet.fiammachain.io/

16. Check Balance & Create Validator & Check Validator:

Check balance:

fiammad q bank balances $(fiammad keys show "wallet_name" -a)

Create Validator:

  cd $HOME
# Create validator.json file
echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(fiammad comet show-validator | grep -Po '\"key\":\s*\"\K[^"]*')\"},
    \"amount\": \"10000ufia\",
    \"moniker\": \"JosephTran\",
    \"identity\": \"891BC6B7C0D28458\",
    \"website\": \"www.josephtran.xyz\",
    \"security\": \"@josephtran102\",
    \"details\": \"I love blockchain ❤️\",
    \"commission-rate\": \"0.05\",
    \"commission-max-rate\": \"0.2\",
    \"commission-max-change-rate\": \"0.01\",
    \"min-self-delegation\": \"1\"
}" > validator.json
# Create a validator using the JSON configuration
fiammad tx staking create-validator validator.json \
    --from josephtran \
    --chain-id fiamma-testnet-1 \
    --fees 3ufia \
    -y

Check Validator:

fiammad q staking validator $(fiammad keys show "wallet_name" --bech val -a)
