A 5-minute on-ramp for readers who've never touched the XRP Ledger. Plain English, no jargon hand-waving. By the end you'll know what XRPL is, what tokens on it look like, what makes it different for institutions, and which of our six services answers what you came here for.
The XRP Ledger (XRPL) is an open-source public blockchain that's been running continuously since 2012. It settles transactions every 3 to 5 seconds, has a built-in DEX (decentralized exchange), and natively supports issuing your own tokens. No mining, no proof-of-work; it uses a consensus protocol run by independent validators.
The native token is XRP, a fixed 100-billion-supply asset used to pay tiny transaction fees (a fraction of a cent each). Anyone can read every transaction that's ever happened on XRPL by querying a public node. No accounts, no API keys, no gatekeepers.
Why it matters for finance. XRPL was designed from day one for moving value, not running smart contracts. Settlement is fast and final (no probabilistic confirmations), fees are predictable, and the protocol has native support for issued assets, trust limits, escrow, and on-ledger trading. Banks, custodians, and stablecoin issuers have been quietly building on it for years.
An XRPL wallet is just a key pair. The public side is your address: a 25-34 character string that starts with the letter r. Example: rKxTzCKYKPPdXEzuioEQ6KekQK26w2DBd5. Anything sent to that address shows up on the ledger immediately and stays there permanently.
You'll see addresses everywhere on this site. Some belong to exchanges (Bitstamp, Kraken, Coinbase). Some belong to issuers (Ripple, Ondo, OpenEden, Société Générale). Some belong to bots, market makers, and anonymous holders. The behavior visible on the ledger is what tells you which is which.
To receive any token other than XRP, an address has to first set up a trustline to the issuer of that token. This is XRPL's way of saying "I'm willing to hold this asset from this specific issuer." Most retail wallets only hold XRP and have no trustlines; institutional wallets often have dozens.
XRPL supports issued assets natively. Any address can issue a token; trustlines determine who's willing to hold it. The most-watched issued asset is RLUSD, Ripple's regulated USD stablecoin (~93,000 trustlines, the largest IOU on XRPL by every measure).
A growing class of tokens are real-world assets (RWAs): on-chain representations of off-chain financial instruments. Examples currently live on XRPL include Ondo's tokenized US Treasuries (OUSG), OpenEden's T-Bill tokens (TBL), Société Générale's euro stablecoin (EURCV), Guggenheim's Digital Commercial Paper (DCP), and Justoken's megawatt-hour tokens (JMWH). When you see a headline like "BlackRock tokenizes a money-market fund," XRPL is one of the chains where that kind of thing actually settles.
Why this matters. If finance is moving on-chain, it's moving as tokenized assets that look like the ones above. Watching that activity in real time is what XR-Vault does for RWAs and what XR-Pulse does for every $50k+ payment on the ledger.
A permissioned domain is XRPL's mechanism for letting institutions run regulated trading venues on the same public ledger as the open DEX. An owner address declares which on-chain credentials are required to join (e.g., "must hold an accredited-investor credential issued by Wallet X"), and other addresses join by holding any accepted credential. Trades inside the domain are visible on the public ledger, but only credentialed counterparties can fill them.
This is the standard the industry has been waiting for. Compliance is on-chain, settlement is on-chain, but access is gated by real institutional identity. The standard is called XLS-80 (PermissionedDomains); the trading layer that runs inside one is XLS-81 (Permissioned DEX).
XR-Trust is the public directory of every permissioned domain on XRPL, surfaces the credentials each requires, and ties owner addresses to operator-signed institutional identity where available.
x402 is an open standard for machine-payable APIs. When an agent calls an x402 endpoint, the server returns HTTP 402 with payment options. The agent signs an on-chain payment matching one of those options, re-sends the request with a payment-signature header, and the server verifies + runs + settles. No accounts, no API keys, no monthly invoices. An AI agent with an XRPL wallet can discover an API, pay it, and consume the response inside a single request cycle.
Every paid endpoint on this site speaks x402 v2 on XRPL mainnet. Pay in XRP or RLUSD, either works. Verification and settlement go through the t54 XRPL facilitator. Pricing is per-call or per-time-window (XR-Pulse also sells live WebSocket subscriptions from $0.50/hour).
Why this matters. AI agents are starting to do real economic work (price queries, data lookups, transaction routing) and they need a payment standard that doesn't require an account setup with every vendor. x402 + XRPL settlement is one of the cleanest answers to that, and it's the moat under every paid endpoint here.
Six on-chain data services that read the XRP Ledger so you don't have to run your own node. Each one answers a different question about what's happening on XRPL. The same backend that serves the public dashboards on this site is exposed as a paid x402 API for AI agents and integrators.
Two surfaces, one backend. The dashboards here are free; agents pay per call or stream live. Everything is on-chain settled. No accounts, no API keys, no onboarding calls. The full pricing table is at /pricing/.
