The XRP Ledger Foundation has introduced a draft amendment aimed at enhancing trading on its decentralized exchange through the "AMM Swappable Curves" proposal. This initiative would allow users and liquidity providers to select different pricing formulas when creating liquidity pools, marking a significant evolution of the XRPL's Automated Market Maker (AMM) system, which launched on the mainnet in March 2024. The proposal introduces two new curve types: StableSwap, designed for assets trading near parity like stablecoins, and concentrated liquidity, which allows providers to allocate capital more efficiently around active price ranges. This "pluggable curve architecture" would enable multiple AMM models to coexist, offering more accurate pricing and reduced slippage for stable asset pairs, and improved capital efficiency for large liquidity providers. Currently a draft, the amendment was posted by the XRP Ledger Foundation on May 26 and filed on GitHub by developers Denis Angell and Roman Thpt. It awaits approval from validators, with stakeholders encouraged to monitor ongoing discussions for further developments.
