A brand new modification proposal submitted to the XRP Ledger Basis’s repository on Might 26 would basically redesign how liquidity swimming pools operate on the XRP Ledger — introducing a number of curve varieties, concentrated liquidity, and a future absolutely programmable AMM structure that mirrors probably the most superior decentralized alternate infrastructure at the moment working on Ethereum.
The proposal, titled AMM Swappable Curves and designated XLS Dialogue #547, was submitted by Denis Angell (@dangell7) and Roman Thpt (@RomThpt) — each lively contributors to the XRPL codebase — and is at the moment in draft standing awaiting group assessment, per the GitHub dialogue thread. It builds straight on XLS-30, the modification that launched XRPL’s unique automated market maker in 2024.

The Drawback The Proposal Solves
The present XRP Ledger AMM operates on a single invariant: the fixed product system — the identical mannequin utilized by Uniswap v2, the place liquidity is unfold uniformly throughout all worth ranges. The proposal identifies three structural gaps that restrict the present system’s competitiveness.
The primary is capital inefficiency. Spreading liquidity uniformly signifies that solely a small fraction is ever lively close to the present market worth — making it much less enticing for liquidity suppliers than concentrated options. The second is curve inflexibility. Unstable buying and selling pairs profit from fixed product swimming pools. Stablecoin pairs profit from StableSwap curves, which reduce slippage between carefully correlated belongings. Lengthy-tail or asymmetrically weighted pairs profit from Balancer-style weighting.
Forcing all pairs into one mannequin is a structural drawback, per the proposal. The third is composability. The XRPL fee engine already routes throughout AMM swimming pools and its native order guide — including curve variety multiplies accessible liquidity sources with out requiring modifications to present pathfinding logic.
What The Modification Would Introduce
The proposal introduces a pluggable curve structure — pool creators choose their most popular curve sort at creation time from an preliminary set of three. Curve 0 is the present fixed product mannequin, preserving full backward compatibility with all present XLS-30 swimming pools. Curve 1 is Concentrated Liquidity — equal to Uniswap v3 — permitting liquidity suppliers to focus on particular worth ranges for dramatically larger capital effectivity. Curve 2 is StableSwap — equal to Curve Finance v1 — optimized for stablecoin and correlated asset pairs the place minimal slippage issues most, per the proposal’s specification.
A fourth curve sort — Good AMM — is reserved for a forthcoming companion specification. It might enable pool creators to deploy WebAssembly binaries offering absolutely customized swap arithmetic, dynamic charges, and lifecycle hooks together with earlier than and after swap, deposit, and withdrawal occasions. The structure deliberately mirrors the host ABI and sandbox mannequin already being developed for XLS-100 Good Escrows — that means the WASM runtime infrastructure is being constructed as soon as and reused throughout a number of XRPL options, per the proposal.
Why It Issues For XRP
A number of swimming pools per token pair — one for every curve sort — would function concurrently with out affecting present swimming pools. The XRPL’s fee engine would route throughout all of them routinely, deciding on the optimum liquidity supply for every transaction with none modifications required from finish customers or present integrations, per the technical specification.
This growth marks a pivotal second for the XRP Ledger’s DeFi infrastructure. A protocol that already hosts over $2 billion in tokenized real-world belongings and processes $1.93 billion in month-to-month stablecoin transfers gaining Uniswap v3-grade concentrated liquidity and Curve Finance-style secure swimming pools would characterize a significant step towards institutional-grade on-chain liquidity — precisely the infrastructure that the asset managers, banks, and stablecoin issuers at the moment constructing on XRPL will ultimately require.
