Create Systemd Service

Systemd Unit File 
sudo tee /etc/systemd/system/stabled.service > /dev/null <

Check Sync Status

Verify Synchronization 
stabled status 2>&1 | jq .SyncInfo
Sync Status
When catching_up is false, your node is fully synced and ready to create a validator.

Wallet & Validator

Final Steps

1. Create or Import Wallet

New Wallet 
stabled keys add $WALLET
Restore Existing Wallet 
stabled keys add $WALLET --recover
Save Wallet Addresses 
WALLET_ADDRESS=$(stabled keys show $WALLET -a)
VALOPER_ADDRESS=$(stabled keys show $WALLET --bech val -a)

echo "export WALLET_ADDRESS=$WALLET_ADDRESS" >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS=$VALOPER_ADDRESS" >> $HOME/.bash_profile

source $HOME/.bash_profile

2. Check Balance

Query Balance 
stabled query bank balances $WALLET_ADDRESS
Get Testnet Tokens
Make sure your wallet has enough testnet tokens before creating a validator. You can request tokens from the Stable testnet faucet.

3. Create Validator

Create Validator Transaction 
stabled tx staking create-validator \
  --amount 1000000astable \
  --from $WALLET \
  --commission-rate 0.1 \
  --commission-max-rate 0.2 \
  --commission-max-change-rate 0.01 \
  --min-self-delegation 1 \
  --pubkey $(stabled tendermint show-validator) \
  --moniker "$MONIKER" \
  --identity "" \
  --website "" \
  --details "Community Validator Node" \
  --chain-id $CHAIN_ID \
  --gas auto --gas-adjustment 1.5 \
  --gas-prices 0.005astable \
  -y
Customize Your Validator
Tip: Update the --moniker, --identity (keybase.io ID), --website, and --details fields to personalize your validator. Adjust commission rates according to your strategy.
