Listing XRP on a cryptocurrency exchange involves a structured approach to ensure security, compliance, and seamless user experience. This guide outlines the essential steps and best practices for custodial exchanges that manage user funds and support trading between digital assets and fiat currencies. Whether you're expanding your asset offerings or integrating XRP for the first time, this comprehensive walkthrough covers everything from account setup to fund flows.
Understanding the Benefits of Listing XRP
Exchanges like the fictional Alpha Exchange—used in this guide for illustration—often seek to list XRP due to growing market demand and fast settlement capabilities on the XRP Ledger. By adding XRP/USD and BTC/XRP trading pairs, exchanges empower users to:
- Deposit XRP from their personal wallets into the exchange
- Withdraw XRP back to the XRP Ledger
- Trade XRP against other cryptocurrencies and fiat currencies
These features enhance liquidity, attract new users, and improve platform utility.

Prerequisites for Supporting XRP
Before launching XRP trading, an exchange must meet two core technical requirements:
- Create and manage XRP Ledger accounts
- Maintain accurate balance sheets for off-ledger holdings
Additionally, exchanges should review regulatory guidelines and technical precautions related to token handling and transaction processing.
Key Consideration: Partial Payments
The XRP Ledger supports partial payments, where a sender can request that a transaction succeed even if only part of the intended amount is delivered. This means the Amount field in a transaction does not guarantee what is actually received.
Always use the delivered_amount field in transaction metadata to confirm how much XRP was received.This feature can be exploited by malicious actors to send less than expected while still triggering a successful deposit. Therefore, exchanges must validate incoming transactions carefully.
For more details, refer to the official Partial Payments documentation.
Setting Up Secure XRP Ledger Accounts
XRP is stored in accounts (also called wallets or addresses) on the XRP Ledger. Unlike some blockchains, each account requires a reserve of XRP (currently 10 XRP) to prevent spam. Accounts cannot be deleted easily, so exchanges should avoid creating unnecessary ones.
Recommended Account Structure: Hot, Warm, and Cold Wallets
To balance security and operational efficiency, exchanges should implement a tiered wallet system:
1. Cold Wallet (Maximum Security)
- Stores the majority of customer and institutional XRP
- Secret key is kept offline at all times
- Used as the primary deposit address for users
- Compromise risks include permanent loss of funds or irreversible control takeover
2. Hot Wallet (High Availability)
- Online and connected to trading systems
- Handles day-to-day withdrawals and deposits
- Enables instant processing but carries higher risk if breached
3. Warm Wallet (Optional Intermediate Layer)
- Semi-offline; keys are not continuously online
- Can use multi-signature schemes for added security
- Acts as a buffer between cold and hot wallets
This layered approach minimizes exposure while maintaining liquidity.

Managing On-Ledger vs Off-Ledger Balances
Exchanges operate two types of XRP balances:
On-Ledger XRP
- Held directly on the XRP Ledger
- Verifiable via public addresses and blockchain explorers
- Counterparty is the decentralized network itself
Off-Ledger XRP
- Internal accounting entries managed by the exchange
- Represent user credits within the platform
- Counterparty is the exchange
Crucially, the total on-ledger balance must always equal or exceed the sum of all off-ledger user balances to ensure solvency.
Handling XRP Amounts: Drops vs XRP
XRP is divisible into drops, where:
1 XRP = 1,000,000 drops
All internal systems should store balances in integer drops to avoid floating-point errors. However, user interfaces should display values in XRP for clarity.
One drop (.000001 XRP) is the smallest unit and cannot be subdivided further—important when calculating exchange rates.
Flow of Funds: Deposit, Trade, Rebalance, Withdraw
Once accounts are set up, funds move through four primary stages.
1. Deposit XRP into Exchange
When a user deposits XRP:
- They send XRP to the exchange’s cold wallet with a destination tag (e.g., user ID 789)
- The exchange monitors incoming payments using APIs (e.g., WebSocket)
- Upon detection, it credits the user’s off-ledger balance
⚠️ Best Practice: Set the asfRequireDest flag on all receiving accounts to enforce destination tags and prevent misdirected deposits.Example:
- Charlie sends 50,000 XRP to Alpha Exchange’s cold wallet with tag
789 - System detects payment and updates Charlie’s balance from 0 → 50,000 XRP
2. Trade XRP on the Exchange
Users trade off-ledger XRP balances internally. These trades:
- Do not interact with the XRP Ledger
- Are settled instantly within the exchange’s system
- Require real-time balance tracking
Customers holding XRP in external wallets can also trade directly on the decentralized exchange (DEX) built into the XRP Ledger.
3. Rebalance XRP Holdings
To maintain security and liquidity, exchanges transfer XRP between wallets:
- Move funds from cold to hot wallet before expected withdrawals
- Return excess funds from hot to cold after peak activity
Each transfer incurs a small transaction cost (a few drops), but preserves overall reserves.
Example:
- Transfer 80,000 XRP from cold → hot wallet
- Cold balance decreases; hot balance increases
- Total reserve remains unchanged
4. Withdraw XRP from Exchange
When a user withdraws:
- The exchange debits their off-ledger balance
- Sends equivalent XRP from its hot wallet to the user’s specified address
- Confirms transaction via ledger verification
Example:
- Charlie withdraws 25,000 XRP
- Off-ledger balance: 50,000 → 25,000
- Hot wallet sends 25,000 XRP to Charlie’s personal address
Frequently Asked Questions (FAQ)
Q: Why are destination tags important for deposits?
A: Destination tags allow exchanges to identify which user sent a deposit. Without them, multiple users sending to the same address could cause confusion or lost funds.
Q: Can I use fractional XRP below one drop?
A: No. One drop (0.000001 XRP) is the smallest unit on the XRP Ledger and cannot be subdivided.
Q: What happens if my hot wallet is compromised?
A: If only the hot wallet is breached, losses may be limited depending on how much was stored there. Cold wallet funds remain safe if properly secured offline.
Q: Do I need to comply with regulations when listing XRP?
A: Yes. While this guide focuses on technical integration, exchanges must also follow local financial regulations, KYC/AML procedures, and reporting requirements.
Q: How do partial payments affect deposit validation?
A: Always check delivered_amount instead of Amount in transaction metadata. A sender might pay less than expected if partial payments are enabled.
Q: Is multi-signature support available on the XRP Ledger?
A: Yes. You can use multi-signing for warm or cold wallets to require multiple approvals before executing transactions—enhancing security significantly.
Final Recommendations
Successfully listing XRP requires robust infrastructure, clear accounting practices, and proactive security measures. Exchanges should:
- Use destination tags universally
- Monitor transactions in real time
- Store most funds in cold storage
- Regularly audit on-ledger vs off-ledger balances
Integrating with reliable tools and APIs ensures smooth operations at scale.
