XRP 账本基金会已发布 AMM v2 的新草案标准，拟对 XRP 账本去中心化交易所进行重大升级。该标准引入新的池曲线模型——恒定乘积、集中流动性和 StableSwap——旨在提升 XRP Ledger DEX 上不同资产市场的流动性、定价稳定性和资本效率。该提案通过允许流动性池使用超过一种定价模型，来扩展当前自动做市商框架，并超越主要依赖恒定乘积模型的现有 XLS-30 AMM 设计。这些新模型旨在支持稳定币、外汇交易对、现实世界资产以及其他相关代币，这些资产需要更紧密的定价和更低的滑点。
Multi-Curve Pool Design for XRPL DEX
The AMM v2 proposal introduces a pluggable pool structure for the XRPL DEX, allowing liquidity pool creators to select from different curve models depending on market conditions and asset type.
Constant Product pools are similar to the design used by Uniswap v2 and are suitable for more volatile asset pairs.
Concentrated Liquidity pools are inspired by Uniswap v3. They allow liquidity providers to place funds within selected price ranges rather than across the full market range. This design can improve capital use when trading stays inside active price bands.
StableSwap pools are designed for assets that trade closely together, such as stablecoins, tokenized cash products, FX pairs, and certain real-world asset markets. These pools are intended to provide smoother pricing and lower slippage when assets have similar values.
Benefits for Stablecoins, FX, and Real-World Assets
The proposed standard is expected to improve trading conditions for assets such as RLUSD, USDC, and other stable or correlated tokens on the XRP Ledger. Lower slippage and tighter spreads are key goals of the upgrade.
For liquidity providers, the AMM v2 framework may allow more targeted use of capital. Instead of spreading liquidity across a wide price range, providers could deploy funds where trading activity is most likely to occur.
The XRP Ledger Foundation said the changes are intended to support deeper liquidity and more stable pricing on the XRPL DEX. These features are relevant for institutional DeFi applications, where predictable execution and market depth are important. The upgrade also supports the XRP Ledger's wider tokenization focus, as real-world assets, stablecoins, and FX markets are growing areas of blockchain finance where AMM design affects on-chain trading efficiency.
XRP Ledger Ecosystem Developments
AMM v2 提案继 XRP 账本生态中的其他进展之后推出。Yellow 于 10 月与 XRP 账本 EVM 侧链集成，使用户能够访问高频交易、非托管结算以及用于数字资产和现实世界资产的跨链流动性。EVM 侧链连接为兼容以太坊的应用程序提供了进入 XRP 账本生态的另一条路径，同时支持更广泛的 DeFi 工具，并保持与 XRPL 流动性和资产市场的联系。
另据，RealFi Payment Solutions 正与 Shopify 合作，为全球电商商户开发一款基于 XRP 账本的支付和奖励应用。Shopify 服务于数百万商户，使该合作成为将基于 XRPL 的基础设施与零售支付用例连接起来的努力案例。
XRP 账本基金会的 AMM v2 标准仍处于提案阶段，其采用取决于生态系统审查和实施。
