The XRP Ledger (XRPL) continues to evolve as a powerful platform for decentralized finance (DeFi) innovation. Earlier this year, the RippleX team introduced the XLS-30d technical specification, a proposal to integrate a protocol-native automated market maker (AMM) directly into the XRPL’s existing orderbook-based decentralized exchange (DEX). This advancement aims to enhance liquidity, simplify trading, and empower developers with robust tools for building next-generation financial applications.
Now, that vision is becoming a reality: the AMM Devnet is live and open for testing. Developers worldwide are invited to explore its capabilities, build integrations, and help shape the future of decentralized trading on XRPL.

What Is the XRPL AMM?
The XRPL Automated Market Maker (AMM) is not just another DeFi add-on—it's a core protocol-level feature designed to coexist seamlessly with the ledger’s established Central Limit Order Book (CLOB) DEX. Unlike many blockchains where AMMs operate as smart contracts deployed by third parties, XRPL’s AMM is natively embedded, meaning it benefits from enhanced security, efficiency, and reliability without relying on external contract logic.
This integration enables developers to create fluid trading experiences, retail financial products, and advanced liquidity solutions—all powered by XRPL’s ultra-fast settlement, negligible fees, and decentralized consensus.
Core Advantages of XRPL’s Native AMM
- Built directly into the XRP Ledger protocol
- Operates alongside the existing CLOB-based DEX
- Enables single-sided liquidity provisioning
- Resistant to front-running and Miner Extractable Value (MEV)
- Features a unique continuous auction mechanism to reduce impermanent loss
These features make the XRPL AMM particularly attractive for enterprise developers, fintech innovators, and DeFi builders seeking scalable, secure infrastructure.
Understanding XLS-30d: The Foundation of XRPL’s AMM
XLS-30d is the technical blueprint behind the new AMM functionality. It introduces several groundbreaking mechanisms designed to improve capital efficiency, user experience, and ecosystem fairness.
Key Features of XLS-30d
Protocol-Native Architecture
As a foundational component of the XRP Ledger, the AMM does not require developers to deploy custom smart contracts. This eliminates common risks such as code vulnerabilities, reentrancy attacks, or gas inefficiencies seen on other platforms. Instead, developers can interact with standardized, audited functions—making development faster and safer.
Continuous Auction Mechanism
One of the most innovative aspects of XLS-30d is its continuous auction system, which incentivizes arbitrageurs to maintain price equilibrium across markets.
- Arbitrageurs bid for the right to correct price discrepancies.
- Each auction lasts 24 hours and runs at near-zero fees.
- Profits from auctions are partially redistributed to previous arbitrageurs and partially burned.
- This model reduces impermanent loss for liquidity providers while ensuring tight spreads and rapid price convergence.
This mechanism aligns incentives across participants—LPs earn more stable returns, traders get better prices, and arbitrageurs are consistently rewarded.
Single-Sided Liquidity Provision
Traditionally, AMMs require liquidity providers to deposit two assets in a pair (e.g., XRP/USD). XRPL simplifies this process by allowing single-sided deposits.
When an LP contributes only one asset, the protocol automatically swaps a portion of it to balance the pool. This removes complexity for users and encourages broader participation in market making—even with small holdings.
MEV Resistance and Fair Transaction Ordering
Thanks to XRPL’s federated consensus model and canonical transaction ordering, the network avoids the pitfalls of MEV (Miner Extractable Value) common on proof-of-work chains.
There are no miners to prioritize high-fee transactions. Instead, validators collectively agree on transaction order, making front-running practically impossible. This ensures fair access for all traders and strengthens trust in the system.
Seamless CLOB-DEX Integration
The AMM doesn’t replace the existing orderbook DEX—it enhances it. When a trade occurs, the system evaluates whether executing through the liquidity pool, the order book, or a hybrid approach yields the best price.
This dynamic routing optimizes execution quality and increases overall market depth—an advantage few blockchains offer natively.
Why Build an AMM on XRPL?
The addition of an AMM significantly expands what’s possible on the XRP Ledger. Here’s why this matters:
Enhanced Liquidity Access
AMMs provide continuous liquidity regardless of market conditions. By enabling any user to become a liquidity provider—even with small amounts—the XRPL democratizes market-making opportunities.
Lower Barriers to Entry
With single-sided deposits and no need for complex smart contracts, even novice developers and users can participate in DeFi. The simplified UX encourages adoption across retail and institutional audiences.
Enterprise-Grade Performance
XRPL processes transactions in 3–5 seconds with fees less than $0.01. Combined with MEV resistance and deterministic execution, this makes it ideal for mission-critical financial applications.
Developer Empowerment
RippleX provides comprehensive documentation, open-source tooling, and active community support. Developers can start building immediately using standard XRPL APIs.

How Does It Compare? CLOB vs AMM on XRPL
While both systems serve similar purposes—facilitating asset exchange—they differ fundamentally in design and user experience:
- Trading Structure: CLOB matches buy/sell orders via an order book; AMM uses algorithmic pools for instant swaps.
- Liquidity Model: In CLOBs, market makers compete individually; in AMMs, liquidity is pooled collectively.
- Price Determination: CLOB prices reflect supply/demand dynamics; AMM prices follow predictable bonding curves based on pool ratios.
- User Accessibility: CLOBs favor experienced traders; AMMs offer simplicity for everyday users.
- Market Participation: CLOBs rely on professional market makers; AMMs allow anyone to provide liquidity.
Together, these models complement each other, offering flexibility and resilience within the same ecosystem.

Frequently Asked Questions (FAQ)
Q: What is the difference between XRPL’s AMM and Ethereum-based AMMs?
A: Unlike most AMMs that run as smart contracts (like Uniswap), XRPL’s AMM is built into the protocol itself. This eliminates smart contract risks, reduces costs, and integrates directly with the native DEX.
Q: Can I deploy my own AMM pool on the Devnet?
A: Yes! Developers can create and manage liquidity pools during the Devnet phase to test trading logic, pricing behavior, and integration workflows.
Q: Will there be incentives or rewards during testing?
A: While no official reward program has been announced yet, active contributors may receive recognition or early access opportunities when mainnet launches.
Q: How will mainnet activation work?
A: Once testing concludes, RippleX will submit an amendment proposal. If approved by over 80% of validators for at least two consecutive weeks, XLS-30d will activate on mainnet.
Q: Is the AMM compatible with existing XRPL wallets?
A: Most modern XRPL wallets will need updates to support AMM-specific transactions. SDKs and libraries are being updated to streamline integration.
Q: Does the AMM support stablecoin pairs?
A: Yes—any issued token on XRPL, including IOU-based stablecoins, can be used in AMM pools.
The future of decentralized exchange on XRPL is here—and it's more efficient, inclusive, and secure than ever before. Whether you're a developer, liquidity provider, or DeFi enthusiast, now is the time to get involved.
