➡️ Let's get started

sudo systemctl start fiammad && sudo journalctl -u fiammad -f -o cat

➡️ Log Command

journalctl -u fiammad -f -o cat

➡️ Create wallet

fiammad keys add

don't forget to backup the wallet words!

➡️ Import wallet

fiammad keys add  --recover

➡️ Faucet

➡️ Create Validator

Reminder: You can't create a validator without Sync. You must have to catch the latest block.

cd $HOME

The code below will give you pubkey. Save it. You'll need it.

fiammad tendermint show-validator

nano validator.json

Copy the below directly. Make the changes and save (ctrl+x, y, enter).

{
        "pubkey": ,
        "amount": "10000ufia",
        "moniker": "myvalidator",
        "identity": "optional identity signature (ex. UPort or Keybase)",
        "website": "validator's (optional) website",
        "security": "validator's (optional) security contact email",
        "details": "validator's (optional) details",
        "commission-rate": "0.1",
        "commission-max-rate": "0.2",
        "commission-max-change-rate": "0.01",
        "min-self-delegation": "1"
}

fiammad tx staking create-validator $HOME/validator.json \
    --from= \
    --chain-id=fiamma-testnet-1 \
    --gas auto \
    --gas-adjustment 1.5

➡️ Delegate to Yourself

Find your valoper address with the code below

fiammad q staking validator $(fiammad keys show  --bech val -a) --node=http://localhost:657

fiammad tx staking delegate  10000ufia \
--chain-id fiamma-testnet-1 \
--from "" \
--gas auto \
--gas-adjustment 1.5

➡️ Edit Validator

fiammad tx staking edit-validator \
--chain-id fiamma-testnet-1 \
--commission-rate 0.1 \
--new-moniker "" \
--identity "" \
--details "" \
--website "" \
--security-contact "" \
--from "" \
--node http://localhost:657 \
--gas auto \
--gas-adjustment 1.5

➡️ Complete deletion

cd $HOME
sudo systemctl stop fiammad
sudo systemctl disable fiammad
sudo rm -rf /etc/systemd/system/fiammad.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/fiammad
sudo rm -f $(which fiamma)
sudo rm -rf $HOME/.fiamma $HOME/fiamma
sed -i "/FIAMMA_/d" $HOME/.bash_profile

➡️ Block check

local_height=$(curl -s localhost:657/status | jq -r .result.sync_info.latest_block_height); network_height=$(curl -s https://fiamma-testnet-rpc.mictonode.com/status | jq -r .result.sync_info.latest_block_height); blocks_left=$((network_height - local_height)); echo "Your node height: $local_height"; echo "Network height: $network_height"; echo "Blocks left: $blocks_left"

Your node height - the current block of your node
Network height - the last block of the network
Blocks left - how many blocks your node has left to sync.
