Headline: XRPL Foundation unveils draft AMM “Swappable Curves” to boost StableSwap and DeFi on XRP Ledger The XRPL Foundation has published a draft amendment titled “AMM Swappable Curves” — a proposal to expand the XRP Ledger’s native automated market maker and give builders more flexible liquidity tooling. Submitted by Denis Angell and Roman Thpt, the amendment is still in draft form and must clear XRPL’s amendment process before it can be activated. Why it matters This proposal builds on XLS-30, the native AMM system that launched on XRPL mainnet in March 2024, and aims to make the ledger’s on‑chain DEX better suited for stablecoins, tokenized assets, foreign‑exchange pairs, and other markets that need tighter pricing or higher capital efficiency. If approved, it would let pool creators choose different pricing curves at pool creation, rather than being limited to a single constant‑product model. What the draft proposes - Multiple curve types at pool creation: Pools would be identified by asset pair plus curve type, allowing more than one AMM pool per pair when different curves are used. This contrasts with the current XRPL AMM, which allows only one AMM per asset pair. - Initial curve set: - CurveType 0: Constant‑product (the existing XLS-30 model). Backward compatibility is preserved: existing pools remain unchanged and retain their original pool keys when this type is used. - Concentrated Liquidity: Similar to Uniswap v3, enabling liquidity providers to concentrate capital in specific price ranges to greatly increase capital efficiency. - StableSwap: Designed for assets that trade close to parity (stablecoins, tokenized cash equivalents), lowering slippage for large trades between closely pegged assets. - Future curve reservations: - CurveType 3: Reserved for a weighted model (Balancer‑style). - CurveType 4: Reserved for a Smart AMM with programmable logic. Practical implications Allowing multiple curve types per pair opens several possibilities: a volatile trading pair can run a broad constant‑product pool while a stablecoin pair (or a dedicated stable pool for the same pair) can use StableSwap for tighter pricing. This could benefit RLUSD/USDC, tokenized Treasuries, FX markets, real‑world assets, and other specialized markets on the XRPL DEX. Governance and next steps The proposal remains at an early stage and must pass the XRPL amendment process — which requires at least 80% validator approval for two continuous weeks — before activation. For now, it provides a clear roadmap for XRPL developers to introduce more sophisticated DeFi primitives without disrupting existing pools. Context The curve proposal is one of several initiatives pushing the XRPL beyond payments into richer on‑chain finance. The ecosystem has also been working on native lending pools and Smart Escrows to support broader DeFi functionality. Bottom line If adopted, “AMM Swappable Curves” would give the XRPL a more modular AMM architecture: better capital efficiency and lower slippage for stable and tokenized assets, multiple specialized pools per asset pair, and a path to future programmable AMM logic — all while keeping existing AMMs fully compatible.
