Create wallet ​

Check Sync status, once your node is fully synced, the output will say False

shell
oraid status 2>&1 | jq .SyncInfo

Create wallet

shell
oraid keys add $WALLET

Restore existing wallet

shell
oraid keys add $WALLET --recover

Check balance

shell
oraid q bank balances $(oraid keys show $WALLET -a)

Create validator ​

shell
oraid tx staking create-validator \
--amount 1000000orai \
--pubkey $(oraid tendermint show-validator) \
--chain-id Oraichain \
--moniker "$MONIKER" \
--identity "" \
--details "❤️ Thank you, EigenNode" \
--website "https://eigennode.de/" \
--from $WALLET \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--gas auto --fees 0.025orai \
-y

Security ​

Firewall security Set the default to allow outgoing connections, deny all incoming, allow ssh and node p2p port

shell
sudo apt install -y ufw
sudo ufw default allow outgoing 
sudo ufw default deny incoming 
sudo ufw allow ssh/tcp 
sudo ufw allow 26656/tcp
sudo ufw enable

Delete node ​

DANGER

Please, note before proceeding with the next step! All data will be lost! Make sure you have backed up your keys!

shell
cd $HOME
sudo systemctl stop oraid 
sudo systemctl disable oraid 
sudo rm /etc/systemd/system/oraid.service 
sudo systemctl daemon-reload 
sudo rm -rf $HOME/.oraid
sudo rm -rf $(which oraid)
