➡️ Let's get started

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

➡️ Log Command

journalctl -u symphonyd -f -o cat

➡️ Create wallet

symphonyd keys add 

don't forget to backup the wallet words!

➡️ Import wallet

symphonyd keys add  --recover

➡️ Faucet

Ping Dashboard - Cosmos Blockchain Explorer And Web Wallet

➡️ Create Validator

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

Save your pubkey

symphonyd tendermint show-validator

rm -rf /root/validator.json

nano /root/validator.json

{
  "pubkey": {"@type":"/cosmos.crypto.ed25519.PubKey.......},
  "amount": "1000000note",
  "moniker": "",
  "identity": "",
  "website": "",
  "security": "",
  "details": "",
  "commission-rate": "0.1",
  "commission-max-rate": "0.2",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}

symphonyd tx staking create-validator $HOME/validator.json \
--from=wallet-name \
--chain-id=symphony-testnet-4 \
--gas-adjustment 1.5 \
--gas-prices 0.025note \
--gas auto
-y

➡️ Delegate to Yourself

Find your valoper address with the code below

symphonyd tx staking delegate $(symphonyd keys show  --bech val -a) amount000000note \
--chain-id symphony-testnet-4 \
--from "" \
--gas-adjustment 1.5 \
--gas-prices 0.025note \
--gas auto
--node=http://localhost:${SYMPHONY_PORT}657 \
-y

➡️ Edit Validator

symphonyd tx staking edit-validator \
--chain-id symphony-testnet-4 \
--commission-rate 0.05 \
--new-moniker "" \
--identity "" \
--details "" \
--website "" \
--security-contact "" \
--from "" \
--node http://localhost:${SYMPHONY_PORT}657 \
--gas-adjustment 1.5 \
--gas-prices 0.025note \
--gas auto
-y

➡️ Complete deletion

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

➡️ Block check

local_height=$(curl -s localhost:${SYMPHONY_PORT}657/status | jq -r .result.sync_info.latest_block_height); network_height=$(curl -s https://symphony-testnet-rpc.mictonode.com/status | jq -r .result.sync_info.latest_block_height); blocks_left=$((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.
