# XRPL Testnet Playground

> XRPL Testnet Playground is a free, browser-based playground at https://xrpl.work/ for testing XRP Ledger transactions with disposable Testnet wallets and no real XRP.

The application signs transactions locally in the browser and connects directly to the public XRPL Testnet. A generated or imported Testnet seed can be remembered in browser localStorage until the user disconnects. Users should never enter a Mainnet seed or a wallet that holds value.

The interface uses XRPL terminology: “trust line” is two words in prose, MPT means Multi-Purpose Token, and successful operations are described as validated only after a `tesSUCCESS` result from a validated ledger.

- [Code lab](https://xrpl.work/?tool=code-lab): Isolated XRPL.js examples.

## Supported workflows

- View the latest 50 validated transactions for the connected Testnet account.
- Generate and fund a disposable Testnet wallet, or import an existing funded Testnet seed. The seed is stored only in that browser until disconnect.
- Configure an account to issue trust line tokens, issue balances with direct Payment transactions, create or reset trust lines, and inspect balances and limits.
- Send direct XRP, trust line token, and MPT payments. The payment form does not perform pathfinding or currency conversion.
- Create MPT issuances with asset scale 0–255, an optional explicit maximum amount, up to 1024 UTF-8 bytes of metadata, transfer fees from 0% to 50% in 0.001% units, and selected capability flags.
- Opt a holder wallet into an MPT issuance, approve a holder when Require Auth is enabled, revoke a zero-balance unlocked holder opt-in, issue MPT units, lock balances, claw back units, inspect holders, and destroy an issuance with no outstanding units.
- Mint NFTs, create zero-price destination sell offers, accept those offers, burn owned NFTs, and inspect NFT metadata fields.
- Browse public XRP and trust line token order books without a wallet; create and cancel Testnet limit offers after connecting a wallet.
- Create XRP or trust line token AMM pools, inspect pools and LP balances, add or remove liquidity, and vote on trading fees.
- Create, finish, and cancel time-based XRP escrows using validated ledger close times.
- Run XRPL.js examples in an isolated module worker that cannot access the page DOM, browser storage, or the connected wallet. Executed code can still make network requests.

## Deliberate limitations

- Testnet only; no Mainnet network selector and no real-value transaction support.
- Direct payments only; no pathfinding, partial payments, or currency conversion UI.
- The DEX playground supports XRP and trust line token order books, not MPT order books.
- The AMM creation form supports XRP and trust line token pairs.
- The code worker is isolated from wallet credentials; code examples use generated disposable wallets where signing is required.
- This is an independent developer tool and is not an official XRPL Foundation or Ripple product.

## Implementation

- Client-side HTML, CSS, and JavaScript bundled with webpack.
- `xrpl` JavaScript package version 5.3.0.
- Direct WebSocket connection to `wss://s.altnet.rippletest.net:51233`.
- Sentry Browser SDK for scrubbed error monitoring only; session replay, tracing, logs, and application metrics are disabled.
- Optional Google Analytics remains disabled unless the user accepts the analytics consent prompt.
