➡️ Create wallet

Warning

Don’t forget to backup the wallet words!

layerd keys add $TELLOR_WALLET

➡️ Let’s get started

sudo systemctl restart layerd
journalctl -fu layerd -o cat

➡️ Log Command

sudo journalctl -fu layerd -o cat

➡️ 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
{
	"pubkey": $(layerd tendermint show-validator),
	"amount": "1000000loya",
	"moniker": "Moniker-Name",

}
EOF

layerd tx staking create-validator ./validator.json --chain-id=layertest-3 --gas 300000 --gas-prices="0.00025loya" --from=$TELLOR_WALLET -y

➡️ Delegate to Yourself

layerd tx staking delegate $(layerd keys show $TELLOR_WALLET --bech val -a) 1000000loya --from $TELLOR_WALLET --chain-id layertest-3 --gas 300000 --gas-prices="0.00025loya" -y

➡️ Import wallet

layerd keys add $TELLOR_WALLET --recover

➡️ Edit Validator

layerd tx staking edit-validator \
--chain-id layertest-3 \
--commission-rate 0.05 \
--new-moniker "validator-name" \
--identity "" \
--details "" \
--website "" \
--security-contact "" \
--from $TELLOR_WALLET \
--node http://localhost:${TELLOR_PORT}657 \
--gas 300000 --gas-prices="0.00025loya" \
-y

➡️ Complete deletion

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

➡️ Block check

local_height=$(layerd status | jq -r .sync_info.latest_block_height); network_height=$(curl -s https://tellor-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.
