Gain a basic introduction to the XRP ledger, including its history, core features, and concepts. Learn about the community resources and funding opportunities for building on the ecosystem.

Explore the XRP ledger explorer and inspect a mainnet ledger, then switch networks and set up a testnet account with activation and keys, then send and verify a testnet payment.

Explore the XRP ledger in real time using live net.xrpl.org to visualize ledgers, transactions, and validators. Compare main net, test net, devnet, and side chains for development.

Discover how XRP ledger accounts drive transactions, signing with a master key pair, and explore R addresses, X addresses, destination tags, activation, funding, and reserves.

Generate and activate XRP ledger accounts by deriving the R address from a secret, funding it via the testnet faucet, and securely backing up keys.

activate unfunded XRP ledger accounts by sending a payment using the JavaScript SDK, autofill, and wallet management on testnet; learn the transaction flow, fees, sequence, and verifying results.

Learn how an account deletion works on the XRP ledger, including the account delete transaction, recoverable balance, owner verification, destination address requirements, and the 256 ledgers since last transaction rule.

Take the first hands-on coding step in the XRP Ledger bootcamp as theory meets practice, and get ready to build your first course project as concepts click into place.

Build a fully functional XRP wallet with React.js on the XRP ledger testnet; manage multiple accounts, view balances and transactions, receive and send XRP, import and generate accounts.

Create a React app with Create React App, name it Xpl Dash wallet in VS Code, remove boilerplate, replace assets, run npm start, and prepare for ESLint, Prettier, Sass, Bootstrap.

Configure ESLint, Prettier, Bootstrap, and Sass for a React app, featuring a custom React plugin config, node globals, and disabled prop types and React import checks.

Build a basic app structure with header, main content, and footer by creating components and pages, wiring them in the app, and styling with Sass and constants.

Set up the account management page to display accounts, select an active account, and remove accounts from the wallet, with routing and styling using React Router, Sass, and Bootstrap.

Import real testnet accounts by pasting a family seed, derive the address with the SDK wallet, and store it in a context with local storage for persistent account management.

Generate a new XRP Ledger account by programmatically creating a wallet (seed and address) in a two-step UI, then save the account to the wallet and local storage.

Wire up the account listings to real data, implement select and remove handlers, and enable multiple wallets by managing accounts in context with local storage persistence.

Build a main wallet page with balance and transactions, and implement a balance component that shows spendable XRP by subtracting the reserve from the ledger balance, with a refresh control.

Display XRP transaction history by building a transactions component that queries the ledger for XRP payments, formats transactions with direction, date, amount, and status, and adds refresh and explorer links.

Create a new send page to transmit XRP, wire routes, and build a form for amount, destination, and optional destination tag. Include a spinner and automatic balance refresh after sending.

Add a receive button and modal to display your XRP address, then implement a ledger listener to monitor transactions and trigger toast notifications in a React XRP wallet.

Built a fully functional wallet application using React.js, turning theory into a real project. Preview the next section, where we shift from coding to infrastructure.

Explore the XRP ledger infrastructure, its distributed design, and how nodes validate and propagate transactions using Ripple Decor; set up a node as a submission node and validator.

Rippled powers the XRP ledger by relaying transactions and maintaining a local ledger copy. It supports stock servers, validators, and full history nodes, guided by UNL and dUNL for consensus.

Prepare a Ubuntu Linux server with root access, upgrade all packages, and open ports 22, 80, 443, and 51235, then point DNS to the server for rippled setup.

Log into an Ubuntu box, install and run rippled, verify the server state is full, and open firewall port 51235 to boost peering as you finalize stock node setup.

Configure rippled for WebSocket access via nginx proxy, adjust the ledger history setting, and expose a public WebSocket using port 443 with Letsencrypt certificates; test with Postman.

Convert your stock node into a validator to participate in consensus by creating a public/private key pair and token, configuring domain verification, and securing the rippled setup.

Maintain a healthy rippled server and infrastructure by monitoring uptime and applying patches. Choose manual or automatic upgrades, back up configs, and engage with the XRPL community.
