The XRPL Foundation has introduced a draft proposal called “AMM Swappable Curves” to expand the XRP Ledger’s native automated market maker. Summary XRPL Foundation introduced a draft AMM proposal adding StableSwap and concentrated liquidity to liquidity pools. The upgrade would let pool creators choose curve types without changing existing XLS-30 pools. Stablecoin, RWA and DeFi markets could gain better pricing if validators approve the amendment. The proposal was submitted by Denis Angell and Roman Thpt and remains listed as a draft amendment. The plan builds on XLS-30, the AMM system that went live on XRPL mainnet in March 2024. XLS-30 added native AMM pools to the XRP Ledger DEX, giving users a protocol-level way to provide liquidity and trade assets without relying only on order books. StableSwap and concentrated liquidity enter the plan The proposal would let pool creators choose a pricing curve when creating a new AMM pool. The initial set includes the current constant-product model, a concentrated liquidity model, and a StableSwap model for closely linked assets. Today, we’re publishing a new XRP Ledger Standard for AMM v2.New pool curves StableSwap & Concentrated Liquidity increase capital efficiency and stabilize pricing for stablecoins, FX markets, RWAs and beyond on the XRPL DEX.Details:https://t.co/jU9CrXA1tH pic.twitter.com/ImSioPCDNE— XRP Ledger Foundation (@XRPLF) May 26, 2026 Concentrated liquidity would let liquidity providers focus funds within selected price ranges, similar to Uniswap v3. StableSwap would target assets that trade close to the same value, such as stablecoins or tokenized cash products, where large trades need lower slippage. The proposal also reserves CurveType 3 for a future weighted model, similar to Balancer. CurveType 4 is reserved for a future Smart AMM system with programmable logic. Existing XLS-30 pools would stay compatible The draft keeps backward compatibility as a core part of the design. Existing constant-product pools would keep the same pool key when CurveType is set to 0, which means older XLS-30 pools would continue operating normally. The current XRPL AMM design allows one AMM per asset pair. The proposed structure would identify pools by asset pair and curve type, allowing several pools for the same pair if they use different curves. That change could matter for markets such as RLUSD/USDC, tokenized Treasuries, and other assets that need tighter pricing. It would also allow volatile pairs, stable pairs, and specialized pools to use different liquidity designs instead of one shared model. XRPL DeFi buildout gains another layer The proposal follows other XRPL upgrades aimed at expanding the network beyond payments. As previously reported by crypto.news, the ecosystem has been preparing native lending pools and Smart Escrows to support more on-chain financial activity. The AMM curve proposal remains at an early stage and still needs the amendment process before launch. XRPL documentation says amendments require at least 80% validator approval over two continuous weeks before activation. For now, the proposal gives XRPL developers a path toward more flexible DeFi liquidity. If approved, it could make the XRP Ledger’s AMM system better suited for stablecoins, tokenized assets, and specialized trading pairs without disrupting existing pools.
