The XRP Ledger (XRPL) is one step closer to bridging its most significant gap in decentralized finance. A draft proposal filed Tuesday, called “AMM Swappable Curves,” would extend the network’s native automated market maker (AMM) with three swappable curve types, allowing liquidity providers to choose how their pools price assets. The change is designed to improve capital efficiency for both volatile pairs and near-1:1 assets like stablecoins, while leaving existing constant-product pools untouched. If passed, the amendment could close one of the longest-standing DeFi gaps on XRPL and unlock new liquidity opportunities for the burgeoning ecosystem.
The XRP Ledger has long been known for its speed, low costs, and reliability, but its DeFi capabilities have lagged behind Ethereum and Solana. The native AMM, introduced in March 2024, initially supported only a constant product curve—the same model used by Uniswap V2. While functional, that design forces liquidity providers to spread capital across the entire price range, leading to inefficient use of funds, especially for stablecoin pairs or assets that trade in narrow bands. The new amendment directly tackles this limitation by introducing three additional curve types: constant product (the existing one), concentrated liquidity (similar to Uniswap V3), and StableSwap (optimized for stablecoins and pegged assets). A future programmable Smart AMM is also planned.
Concentrated liquidity allows LPs to allocate capital within specific price ranges, vastly increasing capital efficiency for volatile assets. For example, an XRP/BTC pool could concentrate liquidity around the current trading price, meaning the same amount of capital can support much larger trades. StableSwap, inspired by Curve Finance, uses a flat pricing curve near the peg to minimize slippage for stablecoin swaps. This is particularly relevant as XRPL hosts over $3 billion in tokenized real-world assets (RWAs), including a recent Ripple-JPMorgan pilot that tokenized a corporate bond. Efficient stablecoin trading is critical for such RWAs to function seamlessly.
The proposal comes from a core developer within the XRPL community and is still in draft form. It must go through the XRP Ledger’s amendment process, which involves validator voting and a two-week activation period once consensus is reached. Historically, some amendments have taken months to pass, while others have failed. The community is optimistic, however, given the strong demand for better DeFi tooling. XRPL has seen a surge in tokenized asset issuance, but its DeFi activity remains relatively low compared to other chains. The AMM upgrade could catalyze new projects and attract more liquidity, especially from institutional players looking for low-cost, fast settlement.
Background on XRPL’s AMM development reveals a deliberate, cautious approach. The original AMM went live after years of debate and testing, and it immediately faced criticism for lacking advanced features. The new amendment was likely informed by community feedback and the success of similar curves on Ethereum. The addition of a Smart AMM—a programmable version that can be customized via smart contracts—represents a future step that could enable completely new DeFi primitives. However, the Smart AMM is not part of the current proposal; it will follow in a later upgrade.
To understand the significance of this amendment, consider the evolution of automated market makers. Uniswap’s constant product formula (xy=k) was revolutionary in 2018, but it forced LPs to deposit liquidity across an infinite price range. This meant that a $100 deposit could only facilitate trades of a few dollars without heavy slippage. Uniswap V3 solved this with concentrated liquidity, allowing LPs to set price ranges and earn higher fees on their capital. Curve Finance further optimized for stablecoins with its unique bonding curve. XRPL’s AMM Swappable Curves effectively brings these innovations to the XRP ecosystem, but with a twist: pools can be configured to use any of the three curve types, and users can swap between them as needed.
The technical implementation leverages XRPL’s native features like atomic transactions and the lack of smart contract composability, which paradoxically provides protection against flash loan attacks—a common exploit on Ethereum. A separate XRPL proposal highlights that flash loan attacks are “structurally impossible” on XRPL due to its transaction architecture. This security advantage, combined with the new AMM curves, positions XRPL as a potentially safer and more efficient DeFi platform.
Market reaction to the news has been muted but positive. XRP holders see the amendment as a long-term bullish catalyst, while DeFi builders are evaluating the implications. Ripple, the company most associated with XRP, has not commented directly, but its RWA pilot with JPMorgan suggests institutional interest. If the amendment passes and attracts liquidity, XRPL could compete directly with other DeFi chains for trading volume and total value locked. However, the timeline remains uncertain. The draft must be refined, submitted for formal voting, and then greenlit by at least 80% of validators over a two-week period. Several recent XRPL amendments have stalled due to lack of validator consensus.
Beyond the technical aspects, the proposal underscores XRPL’s strategic pivot toward DeFi. For years, the network was primarily used for cross-border payments and XRP speculation. Tokenized assets and NFTs have gained traction, but DeFi lending and trading have been minimal. The AMM upgrade could be the missing piece. Additionally, the inclusion of a StableSwap curve directly supports stablecoin liquidity, which is essential for any ecosystem that wants to host real-world assets. With over $3 billion in RWAs already issued, the demand for efficient stablecoin swaps is high. The amendment also enables new use cases like automated portfolio rebalancing and yield farming strategies.
In summary, the AMM Swappable Curves proposal represents a significant evolution for the XRP Ledger. By giving LPs control over capital deployment, it could dramatically improve the user experience for traders and liquidity providers alike. The amendment is not yet guaranteed to pass, but its potential impact on XRPL’s DeFi landscape is substantial. The community awaits the next steps in the process, with many hoping that this will finally bridge the gap and unlock the ledger’s full DeFi potential without compromising its core strengths of speed, low cost, and security.
