fi

➡️ Let’s get started

sudo systemctl restart exrpd
sudo journalctl -fu exrpd -o cat

➡️ Log Command

sudo journalctl -fu exrpd -o cat

➡️ Create wallet

Warning

Don’t forget to backup the wallet words!

exrpd keys add $XRPL_WALLET

➡️ Import wallet

exrpd keys add $XRPL_WALLET --recover

➡️ Import private key

exrpd keys unsafe-export-eth-key $XRPL_WALLET

➡️ Create Validator

Reminder

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

rm -rf /root/validator.json

cat > ./validator.json << EOF

➡️ Delegate to Yourself

exrpd tx staking delegate $(exrpd keys show $XRPL_WALLET --bech val -a) 1000000apoa --from $XRPL_WALLET --chain-id exrp_1440002-1 --gas="300000" --gas-prices="240000000000900000axrp" -y

➡️ Edit Validator

➡️ Complete deletion

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

➡️ Block check

local_height=$(exrpd status | jq -r .sync_info.latest_block_height); network_height=$(curl -s https://xrpl-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 "MictoNode 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.
