The XRP Ledger (XRPL) has long been recognized for its speed and low transaction costs, but its decentralized finance (DeFi) capabilities have lagged behind Ethereum-based chains. A major gap has been the lack of flexible automated market maker (AMM) designs. A new draft amendment filed Tuesday, called "AMM Swappable Curves," aims to close that gap by introducing three additional curve types to XRPL's native AMM, giving liquidity providers (LPs) more efficient ways to deploy capital.
The current AMM on XRPL, launched in March 2024, uses a constant product curve (xy=k) inspired by Uniswap V2. While functional, this model is suboptimal for assets that trade near a fixed ratio, such as stablecoins or tokenized real-world assets (RWAs). For those pairs, a constant product curve forces LPs to provide liquidity across an infinite price range, leading to significant capital inefficiency. The proposed amendment would allow pool creators to choose from three "swappable" curve types: constant product, concentrated liquidity, and StableSwap. A programmable "Smart AMM" is also in the pipeline for future upgrades.
Concentrated liquidity, popularized by Uniswap V3, enables LPs to allocate capital within a specific price range, dramatically increasing capital efficiency. For volatile pairs like XRP/USD, this means LPs can earn higher fees with less capital at risk. StableSwap, based on Curve Finance's model, uses a hybrid curve that is nearly flat near the peg, reducing slippage for stablecoin-to-stablecoin trades. The constant product option remains available for pools that require the simplicity of a full-range liquidity curve.
This upgrade comes at a critical time for XRPL. According to data cited in the amendment, more than $3 billion in tokenized real-world assets currently reside on the ledger, including a recent pilot by Ripple and JPMorgan that tokenized corporate bonds. However, DeFi trading volume and total value locked (TVL) remain small compared to Ethereum, in part due to the AMM's limitations. By giving LPs more tools to manage their positions, the XRPL foundation hopes to attract more sophisticated liquidity providers and close the DeFi gap.
Another unique advantage of XRPL is its architectural resistance to flash loan attacks, a vulnerability that has cost Ethereum DeFi billions. Because XRPL transactions are atomic and cannot include composable intra-transaction calls, it is structurally impossible to execute flash loans on the network. This security feature, combined with the new AMM curves, could make XRPL an attractive home for institutional DeFi applications that require both efficiency and safety.
The XRP Ledger has been operational since 2012, primarily as a payments-focused network. It was only in March 2024 that a native AMM was introduced, significantly later than Ethereum's Uniswap (launched 2018) or Solana's Raydium (2021). This delay meant that XRPL missed much of the early DeFi boom, and its AMM lacked the advanced features that traders and liquidity providers had come to expect. For instance, concentrated liquidity, introduced by Uniswap V3 in 2021, became the standard for maximizing capital efficiency on Ethereum. XRPL's constant product model alone could not compete, limiting its appeal to DeFi users.
Moreover, the XRPL's architecture offers a natural defense against one of DeFi's most damaging attack vectors: flash loans. As detailed in a recent draft proposal—related to the AMM upgrade—flash loan attacks are "structurally impossible" on the XRP Ledger. This is because XRPL transactions are atomic and cannot include composable intra-transaction calls, a fundamental design difference from Ethereum's account model. On Ethereum, flash loans have been used to drain hundreds of millions of dollars from protocols like Thorchain, Drift, and KelpDAO. XRPL's immunity to such exploits is a major selling point for risk-averse liquidity providers, especially those handling large volumes of tokenized real-world assets.
The combination of new curve types and inherent security could make XRPL a preferred platform for institutional DeFi. Several traditional financial institutions have already shown interest in tokenizing assets on XRPL, including JPMorgan's pilot with Ripple. However, the lack of a sophisticated AMM has been a bottleneck for secondary trading. The proposed amendment addresses that directly. By enabling StableSwap for stablecoins and concentrated liquidity for volatile pairs, XRPL can offer trading experiences comparable to Ethereum's most popular DEXs while maintaining its low fees and high finality.
The amendment process itself is a testament to XRPL's commitment to decentralization. Unlike Ethereum Improvement Proposals (EIPs) that are often finalized by core developers, XRPL amendments require a two-week voting period by network validators, with an 80% supermajority needed for activation. This system has both advantages and disadvantages. It ensures that no single entity can force through changes, but it also means that upgrades can take months or even years to implement. The "AMM Swappable Curves" draft is now open for community discussion, and a testnet deployment is expected in the coming weeks. If all goes smoothly, the amendment could be live by the end of 2026.
The draft proposal has just been published, and it remains to be seen whether the community will adopt it. Historically, some amendments have taken months or even years to pass, while others have been rejected. If passed, the upgrade could significantly boost XRPL's DeFi ecosystem. Liquidity providers would have the flexibility to optimize their strategies according to the assets being traded. For instance, stablecoin pools could use StableSwap to minimize slippage and maximize capital efficiency, while volatile asset pairs could use concentrated liquidity to target specific price ranges. The constant product curve would remain the default for pools that prefer a straightforward design.
Beyond the immediate technical improvements, the amendment signals a broader shift in the XRPL community's approach to DeFi. For years, developers have focused on payment and settlement use cases, but the network's native AMM was a relatively late addition. Now, with the accumulation of tokenized assets and the growing demand for decentralized exchange functionality, the XRPL seems poised to compete more directly with Ethereum's DeFi ecosystem.
Industry observers have noted that the timing of the proposal aligns with the rapid expansion of tokenized RWAs, a sector that many believe will be a trillion-dollar market. XRPL's low fees and fast finality make it a natural home for such assets, but without efficient trading mechanisms, issuers and holders have had to rely on centralized exchanges or cross-chain bridges. The new AMM curves could enable a vibrant on-chain secondary market for tokenized bonds, stablecoins, and other assets.
The proposal also includes plans for a programmable "Smart AMM" in the future, which would allow developers to deploy custom liquidity functions. This could open the door to innovative DeFi primitives tailored to specific asset classes, such as bond trading with constant maturity or automated portfolio rebalancing. However, the Smart AMM is not part of the current draft and will require separate amendment.
It is important to note that the XRPL foundation does not control the amendment process; it is entirely community-driven. The initial reaction from validators and developers has been cautiously positive, with many acknowledging the need for advanced AMM features. However, some have raised concerns about the complexity of supporting multiple curve types, which could introduce new attack vectors or fragmentation of liquidity. Proponents argue that the modular design allows pools to choose the best curve for their needs, and that the security and reliability of XRPL's base layer will mitigate risks.
As the DeFi landscape evolves, the ability to support diverse trading strategies is becoming a competitive necessity. Ethereum's Uniswap V3 and Curve have set high standards for capital efficiency, and Solana's DeFi protocols offer blazing speed. XRPL's unique combination of low cost, high throughput, and innate security could be a differentiator if it can match those platforms in flexibility. The "AMM Swappable Curves" amendment is a significant step in that direction, but its success will ultimately depend on the community's willingness to adopt changes.
In the meantime, XRPL continues to process millions of transactions daily, primarily for cross-border payments and token issuance. The DeFi sector remains small but growing. With over $3 billion in tokenized assets already on the ledger, the potential for a vibrant DeFi ecosystem is clear. The proposed AMM upgrade, if implemented, could unlock that potential and allow XRPL to close one of its most significant gaps in the decentralized finance space.
