[XRPL Submits Proposal to Upgrade AMM Mechanism] According to a report by Jinse Finance, on May 27, XRP Ledger developers submitted a draft proposal titled 'AMM Swappable Curves,' aiming to introduce three types of switchable curves for XRPL's native automated market maker: constant product, concentrated liquidity, and StableSwap. Additionally, programmable Smart AMM will be added in the future. This upgrade is designed to allow liquidity providers to select the most suitable pricing curve based on asset types, thereby improving capital efficiency. Concentrated liquidity is suitable for trading pairs where most transactions occur within a specific price range, while StableSwap is better suited for stablecoins or pegged assets that are close to a 1:1 exchange ratio. Existing AMM pools will continue to use the current constant product model without requiring migration. This proposal is seen as a significant step toward addressing the shortcomings of XRPL's DeFi infrastructure. Currently, over $3 billion in tokenized real-world assets exist on the XRPL chain, including a recent pilot project between Ripple and JPMorgan for tokenized U.S. Treasury redemptions. However, to enable these assets to trade, lend, or generate yields more efficiently, a more mature DeFi liquidity infrastructure is still needed. That said, the proposal is still in its draft stage and will need to go through XRPL's amendment voting process, which could take several months, with no guarantee of final approval.
