The XRP Ledger Foundation has introduced an ambitious draft proposal that promises to significantly enhance trading and liquidity operations on XRP’s decentralized exchange (DEX). This new initiative, termed AMM Swappable Curves, aims to provide XRPL users and liquidity providers with the ability to select from various pricing models when creating liquidity pools. If implemented, this would represent a substantial upgrade to XLS-30, the current Automated Market Maker (AMM) system that was launched on the mainnet in March 2024.
Transforming User Experience with New Pricing Models
At present, the original XRPL AMM employs a single curve model known as the “constant product” system. While effective for trading volatile assets, this model falls short for stablecoins and tokenized real-world assets (RWAs). The newly announced proposal, shared by the XRP Ledger Foundation via an X post on May 26, seeks to address this limitation by introducing two additional models: StableSwap and concentrated liquidity, designed specifically for the needs of Ledger users and investors.
The Ledger Foundation asserts that these new options could enhance capital efficiency and minimize price slippage. They further highlight that the upgrade would enable more accurate pricing across various markets, including foreign exchange, stablecoins, RWAs, and DeFi trading.
Among the key features of this proposal is the pluggable curve architecture. This innovative upgrade would empower liquidity pool creators to select a pricing formula that best aligns with the types of assets being traded on the Ledger. Rather than confining every market to a single system, the AMM would have the capability to support multiple trading models concurrently.
Notably, the proposal has been put forth by core developers Denis Angell and Roman Thpt and is currently in draft form, meaning it awaits validation. If approved, this amendment would extend XLS-30 without disrupting existing liquidity pools already operational on the Ledger.
Significance of the Proposal for Stablecoins and RWAs
On GitHub, the Foundation elaborated on the StableSwap model within its XLS-30 upgrade proposal. StableSwap is tailored for assets such as USDT and USDC, in addition to tokenized RWAs linked to fiat currencies. Given that these assets generally trade within a narrow price range and exhibit minimal price volatility compared to cryptocurrencies like XRP and Bitcoin, StableSwap could offer tighter pricing and reduced slippage during transactions.
The proposal also introduces a curve diversity feature, which would allow the Ledger to utilize different trading models for various asset pairs. For instance, while volatile assets like XRP or meme coins may benefit from the current model, stablecoins such as USDT and USDC could experience inefficiencies, occasionally leading to suboptimal pricing during trades.
In essence, this proposal would grant Ledger developers and users the flexibility to choose the trading system that best suits the assets in a pool. Stablecoins could leverage StableSwap to maintain steadier prices and minimize price fluctuations during trades, while larger traders and liquidity providers could utilize concentrated liquidity pools to position their funds more strategically near active trading prices, thereby optimizing their capital usage.
