How do I start developing on the XRP Ledger (XRPL)?
Last updated:
Starting development on the XRP Ledger requires understanding its account-based architecture, transaction types, and available SDKs—with xrpl.js (JavaScript) and xrpl-py (Python) being the most accessible entry points for most developers.
## Prerequisites
Essential Skills: Programming fundamentals in JavaScript/TypeScript or Python, JSON understanding, command line comfort, async/await patterns.
Development Environment: Install Node.js (18+) with npm for JavaScript, or Python 3.8+ with pip. Use VS Code or similar editor with good TypeScript/Python support.
SDK Installation: ```bash # JavaScript npm install xrpl
# Python pip install xrpl-py ```
## First Application
Connect to Testnet: ```javascript const xrpl = require('xrpl')
async function main() { const client = new xrpl.Client('wss://s.altnet.rippletest.net:51233') await client.connect() console.log('Connected to XRPL Testnet') // Create funded test wallet const wallet = (await client.fundWallet()).wallet console.log('Address:', wallet.address) console.log('Balance:', await client.getXrpBalance(wallet.address)) await client.disconnect() } main() ```
Send Transaction: ```javascript const payment = { TransactionType: 'Payment', Account: wallet.address, Destination: 'rDestinationAddress...', Amount: xrpl.xrpToDrops('10') }
const prepared = await client.autofill(payment) const signed = wallet.sign(prepared) const result = await client.submitAndWait(signed.tx_blob) ```
## Core Concepts
Account Model: XRPL uses accounts with balances and sequence numbers (not Bitcoin's UTXO model). Minimum 10 XRP reserve required.
Drops: 1 XRP = 1,000,000 drops. All amounts use drops (integers) internally.
Transaction Types: Payments, trust lines, DEX offers, escrows, payment channels, NFTs.
Finality: 3-5 seconds for validated transactions with probabilistic finality.
## Learning Path
Beginner: Build payment bot, balance tracker, QR code generator.
Intermediate: DEX trading bot, token issuer, escrow scheduler, NFT marketplace.
Advanced: Payment channels, multi-sig wallets, hooks integration.
## Resources
- Documentation: https://xrpl.org/docs.html - SDK Docs: https://js.xrpl.org/ (JavaScript), https://xrpl-py.readthedocs.io/ (Python) - Community: XRPL Developers Discord, GitHub examples - Testnet Faucet: https://faucet.altnet.rippletest.net/
Best Practices: Use testnet for development, never commit secrets, validate inputs, check transaction results, implement retry logic, use validated ledgers.
