The XRPL Foundation has introduced a draft amendment titled "AMM Swappable Curves" aimed at enhancing the XRP Ledger's automated market maker (AMM) capabilities. This proposal, submitted by Denis Angell and Roman Thpt, seeks to provide more flexible liquidity tools by allowing pool creators to select different pricing curves at pool creation. This would expand beyond the current single constant-product model, potentially improving capital efficiency and pricing for stablecoins, tokenized assets, and foreign-exchange pairs. The draft suggests multiple curve types, including the existing constant-product model, a concentrated liquidity model similar to Uniswap v3, and a StableSwap model for assets trading close to parity. Future curve types are reserved for more advanced models like a weighted model and a Smart AMM with programmable logic. The proposal is still in its early stages and requires 80% validator approval over two weeks to be activated. If approved, it could significantly enhance the XRPL's DeFi offerings by allowing multiple specialized pools per asset pair and maintaining compatibility with existing AMMs.
