6. Custom Ports:

echo "export KOPI_PORT="19"" >> $HOME/.bash_profile
source $HOME/.bash_profile
sed -i.bak -e "s%:1317%:${KOPI_PORT}317%g;
s%:8080%:${KOPI_PORT}080%g;
s%:9090%:${KOPI_PORT}090%g;
s%:9091%:${KOPI_PORT}091%g;
s%:8545%:${KOPI_PORT}545%g;
s%:8546%:${KOPI_PORT}546%g;
s%:6065%:${KOPI_PORT}065%g" $HOME/.kopid/config/app.toml

sed -i.bak -e "s%:26658%:${KOPI_PORT}658%g;
s%:26657%:${KOPI_PORT}657%g;
s%:6060%:${KOPI_PORT}060%g;
s%:26656%:${KOPI_PORT}656%g;
s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${KOPI_PORT}656\"%;
s%:26660%:${KOPI_PORT}660%g" $HOME/.kopid/config/config.toml

7. Create Service and Start node

sudo tee /etc/systemd/system/kopid.service > /dev/null <<EOF
[Unit]
Description=Kopi Protocol
After=network-online.target
[Service]
User=root
ExecStart=$(which kopid) start
Restart=always
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable kopid
sudo systemctl restart kopid
sudo journalctl -u kopid -f --no-hostname -o cat

8. Wallet

Add New Wallet Key - Save seed

kopid keys add wallet

Recover existing key

kopid keys add wallet --recover

List All Keys

kopid keys list

8.1 Query Wallet Balance

kopid q bank balances $(kopid keys show wallet -a)

8.2 Check sync status

False is synced

kopid status 2>&1 | jq .sync_info.catching_up

8.3 Create Validator

Obtain your validator public key by running the following command:

kopid tendermint show-validator

The output will be similar to this (with a different key):

{"@type":"/cosmos.crypto.ed25519.PubKey","key":"lR1d7YBVK5jYijOfWVKRFoWCsS4dg3kagT7LB9GnG8I="}

Then, create a file named validator.json with the following content:

nano $HOME/validator.json

Change your info, from "pubkey" to "details" and Save them

{
  "pubkey": {
    "@type":"/cosmos.crypto.ed25519.PubKey",
    "key":"<Paste Key here>"
  },
  "amount": "1000000ukopi",
  "moniker": "Node39 Guide",
  "identity": "",
  "website": "https://services.node39.top",
  "security": "[e-mail]",
  "details": "Node39.TOP Member",
  "commission-rate": "0.1",
  "commission-max-rate": "0.2",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}

Finally, we're ready to submit the transaction to create the validator:

kopid tx staking create-validator $HOME/validator.json \
--from=wallet \
--chain-id=luwak-1 \
--fees 100ukopi \
--node=https://kopi-rpc.nodesync.top:443 \
-y

8.4 Delegate Token to your own validator

kopid tx staking delegate $(kopid keys show wallet --bech val -a)  1000000ukopi \
--from=wallet \
--chain-id=luwak-1 \
--fees 100ukopi \
--node=https://kopi-rpc.nodesync.top:443 \
-y

8.6 Withdraw rewards and commission from your validator

kopid tx distribution withdraw-rewards $(kopid keys show wallet --bech val -a) \
--from=wallet \
--chain-id=luwak-1 \
--fees 100ukopi \
--node=https://kopi-rpc.nodesync.top:443 \
-y

8.7 Unjail validator

kopid tx slashing unjail \
--from=wallet \
--chain-id=luwak-1 \
--fees 100ukopi \
--node=https://kopi-rpc.nodesync.top:443 \
-y
