Introduction
The MPTVersion2 amendment (XLS-82) extends Multi-Purpose Token (MPT) support to the XRP Ledger's Decentralized Exchange (DEX), enabling MPT assets to participate natively in Automated Market Maker (AMM) pools, order book offers, cross-currency payments, and check-based transfers. This builds directly on the XLS-33 MPT foundation and the existing XRPL DEX infrastructure (XLS-30).
Rather than introducing new on-ledger objects or a separate trading engine, MPTVersion2 extends existing transaction types — AMMCreate, AMMDeposit, AMMWithdraw, AMMClawback, AMMDelete, CheckCreate, CheckCash, OfferCreate, and Payment — to treat MPT as a first-class asset alongside XRP and IOUs. MPT amounts are identified by mpt_issuance_id in transaction JSON in place of the currency/issuer fields used by IOUs.
This report summarizes a comprehensive performance evaluation of the MPTVersion2 amendment under high-load conditions. Tests were executed in RippleX's private performance network to quantify throughput, consensus latency, CPU/memory utilization, and regression impact relative to the 3.1.2 release baseline.
The results demonstrate that MPT DEX integration is performant and stable, with no material regression against baseline IOU-based DEX operations, and that the amendment can be safely activated without compromising the 5-second consensus target.
