Learn About the XRP Ledger
We believe the best way to stay safe in crypto is to understand what you are using. These are the resources we wish everyone read before adding their first trustline. All curated, all free.
Getting Started with the XRP Ledger
New to the XRPL? These resources cover the fundamentals. Start here if you want to understand what the ledger is, how it works, and why it matters.
Introduction to the XRP Ledger
The official overview of what the XRPL is, how consensus works, and what makes it different from other blockchains.
XRPL Learning Portal
Interactive tutorials that walk you through the basics step by step. Good if you learn by doing rather than reading.
XRP Ledger Explorer
See transactions, accounts, and tokens in real time. Useful for understanding what actually happens on the ledger when you send payments or create trustlines.
Trustlines and Tokens
Trustlines are how the XRPL handles tokens. Before you can hold any token other than XRP, you need a trustline to the issuer. Understanding how they work helps you make better decisions about which tokens to trust.
What Are Trust Lines?
The official technical explanation of trust lines, how they work, and what the balance and limit fields actually mean.
Issued Currencies Overview
How tokens are created and managed on the XRPL. Covers issuance, transfer fees, and the relationship between issuers and holders.
Freezing Tokens
Issuers can freeze individual trust lines or all tokens globally. This page explains what freezing means and when issuers might use it.
Staying Safe on the XRPL
The XRPL is open and permissionless, which means anyone can issue a token. That is a feature, but it also means you need to know what to look for. These resources help you spot red flags and protect yourself.
How Rhyzlo Risk Scoring Works
Our FAQ breaks down the 20+ checks we run on every token, from domain verification to whale concentration detection. Good starting point for understanding what makes a token risky.
Authorized Trust Lines
Some issuers require authorization before you can hold their token. This page explains what that means and how it changes the trust line relationship.
The xrp-ledger.toml File
Domain verification is one of the strongest trust signals. This explains how issuers link their XRPL accounts to a website so tools like Rhyzlo can verify the connection.
Escrow on the XRPL
Escrow lets you lock funds on the ledger with conditions for release. It is useful for vesting schedules, milestone payments, or any situation where you want a trusted time delay without a middleman.
Escrow Overview
The official guide to how escrow works on the XRPL. Covers time-based and conditional escrow, plus the transactions used to create, finish, and cancel them.
XLS-85 Token Escrow Amendment
The amendment that extended escrow to support IOU tokens, not just XRP. This is what powers Rhyzlo's token escrow feature.
Create an Escrow on Rhyzlo
Try it yourself. Our escrow wizard walks you through the process in three steps. Non-custodial, wallet-signed, 0.5% fee.
On-Chain Credentials (XLS-70)
XLS-70 brings verifiable credentials to the XRPL. Think of it as on-chain proof that an issuer has passed KYC, AML, or other checks from a trusted provider. Rhyzlo reads these credentials and factors them into risk scores.
Verifiable Credentials on the XRPL
A plain-language explanation of what on-chain credentials are, who issues them, and why they matter for token trust.
Deposit Authorization
Some accounts use deposit authorization alongside credentials to control who can send them tokens. This explains how that mechanism works.
XRPL Wallets
You need a wallet to interact with the XRP Ledger. Rhyzlo supports four wallets, and each works a little differently. These links take you to the official sites where you can learn more or download them.
