5. Create Service and Start node

# Set Service File
sudo tee /etc/systemd/system/symphonyd.service > /dev/null <<EOF
[Unit]
Description=symphony-testnet
After=network-online.target

[Service]
User=$USER
ExecStart=$(which symphonyd) start --home $HOME/.symphonyd
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable symphonyd
sudo systemctl restart symphonyd
sudo journalctl -u symphonyd -f --no-hostname -o cat

6. Wallet

Add New Wallet Key - Save seed

symphonyd keys add wallet

Recover existing key

symphonyd keys add wallet --recover

List All Keys

symphonyd keys list

6.1 Fund a Wallet

To create a validator, you need to fund the previously created wallet using https://testnet.ping.pub/symphony/faucet

To check wallet balance use command below

symphonyd q bank balances $(symphonyd keys show wallet -a)

6.2 Check sync status

False is synced

symphonyd status 2>&1 | jq .SyncInfo.catching_up

6.3 Create Validator

Change your info here

symphonyd tx staking create-validator \
--amount 1000000note \
--pubkey $(symphonyd tendermint show-validator) \
--moniker "your-moniker-name" \
--identity "your-keybase-id" \
--details "your-details" \
--website "your-website" \
--security-contact "your-email" \
--chain-id symphony-testnet-2 \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--fees 800note \
-y

6.4 Edit Existing Validator

Change your info

symphonyd tx staking edit-validator \
--new-moniker="YOUR MONIKER" \
--identity="IDENTITY KEYBASE" \
--details="DETAILS VALIDATOR" \
--website="LINK WEBSITE" \
--chain-id=symphony-testnet-2 \
--from=wallet \
--gas-adjustment=1.5 \
--gas="auto" \
--gas-prices=1note \
-y

6.5 Delegate Token to your own validator

symphonyd tx staking delegate $(symphonyd keys show wallet --bech val -a) 100000note --from wallet --chain-id symphony-testnet-2 --gas-adjustment 1.5 --gas auto --gas-prices 1note 

6.6 Withdraw rewards and commission from your validator

symphonyd tx distribution withdraw-all-rewards --from wallet --chain-id symphony-testnet-2 --gas-adjustment 1.5 --gas auto --gas-prices 1note 

6.7 Unjail validator

symphonyd tx slashing unjail --from wallet --chain-id symphony-testnet-2 --gas-adjustment 1.5 --gas auto --gas-prices 1note 

6.8 Send Token to another wallet

symphonyd tx bank send wallet <TO_WALLET_ADDRESS> 10000note --from wallet --chain-id  symphony-testnet-2 --gas-adjustment 1.5 --gas auto --gas-prices 1note
