### Setup Python Client and Accounts

Source: https://xrpl.org/docs/tutorials/defi/lending/use-the-lending-protocol/create-a-loan.md

Import necessary libraries and instantiate an XRPL client for Python. This example uses preconfigured accounts for loan creation.

```python
# IMPORTANT: This example creates a loan using a preconfigured
# loan broker, borrower, and private vault.

import json
import os
import subprocess
import sys

from xrpl.clients import JsonRpcClient
from xrpl.models import LoanSet
from xrpl.transaction import autofill, sign, sign_loan_set_by_counterparty, submit_and_wait
from xrpl.wallet import Wallet

```

--------------------------------

### Check and Load Lending Setup Data (Go)

Source: https://xrpl.org/docs/tutorials/defi/lending/use-the-lending-protocol/pay-off-a-loan.md

Ensures lending setup data is available, running a setup script if it's missing. It then loads the borrower's wallet, loan ID, and MPT ID from the setup file.

```go
if _, err := os.Stat("lending-setup.json"); os.IsNotExist(err) {
		fmt.Printf("\n=== Lending tutorial data doesn't exist. Running setup script... ===\n\n")
		cmd := exec.Command("go", "run", "./lending-setup")
		cmd.Stdout = os.Stdout
		cmd.Stderr = os.Stderr
		if err := cmd.Run(); err != nil {
			panic(err)
		}
	}

	data, err := os.ReadFile("lending-setup.json")
	if err != nil {
		panic(err)
	}
	var setup map[string]any
	if err := json.Unmarshal(data, &setup); err != nil {
		panic(err)
	}

	borrowerWallet, err := wallet.FromSecret(setup["borrower"].(map[string]any)["seed"].(string))
	if err != nil {
		panic(err)
	}
	loanID := setup["loanID2"].(string)
	mptID := setup["mptID"].(string)

	fmt.Printf("\nBorrower address: %s\n", borrowerWallet.ClassicAddress)
	fmt.Printf("LoanID: %s\n", loanID)
	fmt.Printf("MPT ID: %s\n", mptID)
```

--------------------------------

### Check and Load Lending Setup Data (JavaScript)

Source: https://xrpl.org/docs/tutorials/defi/lending/use-the-lending-protocol/pay-off-a-loan.md

Verifies if lending setup data exists and runs a setup script if not. Loads borrower, loanID, and mptID from the setup file.

```js
if (!fs.existsSync('lendingSetup.json')) {
  console.log(`
=== Lending tutorial data doesn't exist. Running setup script... ===
`)
  execSync('node lendingSetup.js', { stdio: 'inherit' })
}

const setupData = JSON.parse(fs.readFileSync('lendingSetup.json', 'utf8'))

const borrower = xrpl.Wallet.fromSeed(setupData.borrower.seed)
const loanID = setupData.loanID2
const mptID = setupData.mptID

console.log(`
Borrower address: ${borrower.address}`)
console.log(`LoanID: ${loanID}`)
console.log(`MPT ID: ${mptID}`)
```

    user interface, main frame.
    """
    def __init__(self, url):
        wx.Frame.__init__(self, None, title="TWaXL", size=wx.Size(800,400))

        self.build_ui()

        # Start background thread for updates from the ledger ------------------
        self.worker = XRPLMonitorThread(url, self)
        self.worker.start()
        self.run_bg_job(self.worker.watch_xrpl())
```

--------------------------------

### Ripple Source List Configuration

Source: https://xrpl.org/blog/2026/gpg-key-rotation.md

Example configuration for the Ripple source list file on Debian-based systems. Ensure the 'signed-by' path correctly points to the installed GPG key.

```bash
deb [signed-by=/etc/apt/keyrings/ripple.gpg] https://repos.ripple.com/repos/rippled-deb jammy stable
```

### Set up XRPL Client and Initialize Wallet

Source: https://xrpl.org/docs/tutorials/sample-apps/credential-issuing-service-in-javascript.md

Sets up the XRPL client connection and instantiates a Wallet object by calling initWallet(). This is the initial setup within the main function.

```javascript
async function main() {
  const client = new Client(XRPL_SERVER);
  await client.connect();    

  const wallet = await initWallet();
```

--------------------------------

### Set up JavaScript Client and Account

Source: https://xrpl.org/docs/tutorials/payments/send-a-conditional-escrow.md

Connect to the XRP Ledger testnet, fund a new wallet from the faucet, and obtain a destination address for the escrow.

```javascript
import xrpl from 'xrpl'
import { PreimageSha256 } from 'five-bells-condition'
import { randomBytes } from 'crypto'

const client = new xrpl.Client('wss://s.altnet.rippletest.net:51233')
await client.connect()

console.log('Funding new wallet from faucet...')
const { wallet } = await client.fundWallet()
// const destination_address = 'rPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe' // Testnet faucet
// Alternative: Get another account to send the escrow to. Use this if you get
// a tecDIR_FULL error trying to create escrows to the Testnet faucet.
const destination_address = (await client.fundWallet()).wallet.address
```

### Set up rippledmon instance

Source: https://xrpl.org/docs/infrastructure/configuration/configure-statsd.md

Clone the rippledmon repository and start the Docker Compose service to set up an instance for receiving StatsD metrics. Ensure Docker and Docker Compose are installed.

```bash
git clone https://github.com/ripple/rippledmon.git
cd rippledmon
docker-compose up
```

--------------------------------

### Set Up Python Client and Accounts

Source: https://xrpl.org/docs/tutorials/defi/lending/use-the-lending-protocol/pay-off-a-loan.md

Import necessary libraries and instantiate an XRPL client for Python. This setup includes modules for client connection, transaction models, and wallet handling.

```python
# IMPORTANT: This example pays off an existing loan and then deletes it.

import json
import os
import subprocess
import sys

from xrpl.clients import JsonRpcClient
from xrpl.models import LedgerEntry, LoanDelete, LoanPay, MPTAmount
from xrpl.transaction import submit_and_wait
from xrpl.wallet import Wallet

```

--------------------------------

### Run rippled Server Info Commandline

Source: https://xrpl.org/docs/tutorials/get-started/get-started-http-websocket-apis.md

Use this command to get information about the rippled server. Ensure the configuration file path is correct for your setup. This commandline interface is for administrative purposes and may change without notice.

```bash
rippled --conf=/etc/opt/ripple/rippled.cfg server_info
```
