Create wallet

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

pryzmd status 2>&1 | jq .SyncInfo

Create wallet

pryzmd keys add $WALLET

Restore existing wallet

pryzmd keys add $WALLET --recover

Check balance

pryzmd q bank balances $(pryzmd keys show $WALLET -a)

Create validator

pryzmd tx staking create-validator \
--amount 1000000upryzm \
--pubkey $(pryzmd tendermint show-validator) \
--chain-id indigo-1 \
--moniker "$MONIKER" \
--identity "" \
--details "❤️ Thank you, EigenNode" \
--website "https://eigennode.de/" \

--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \

Security

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

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!

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

Import Key (restore from wallet.backup)

pryzmd keys import $WALLET wallet.backup

Edit existing validator

pryzmd tx staking edit-validator \
--chain-id indigo-1 \
--new-moniker "$MONIKER" \
--identity "" \
--details "❤️ Thank you, EigenNode" \
--website "https://www.eigennode.de/" \
