Now I have comprehensive information to write the overview. Let me compile this into a professional research report format.
Ripple USD (RLUSD): Comprehensive Overview
Core Definition and Technology
Ripple USD (RLUSD) is designed to maintain a constant value of one US dollar. Natively issued on XRP Ledger and Ethereum blockchains, Ripple USD is fully backed by a segregated reserve of cash and cash equivalents and redeemable 1:1 for US dollars. RLUSD is issued by Standard Custody & Trust Company, LLC, a wholly owned subsidiary of Ripple Labs, and is a USD denominated stablecoin created with trust, liquidity, and compliance at its core.
Blockchain Architecture and Multi-Chain Deployment
Ripple USD (RLUSD) is natively issued on the XRP Ledger and Ethereum blockchains. As of late 2025, supply distribution sits at roughly 80% on Ethereum and 20% on XRPL, highlighting network preferences. Ripple said it's testing its U.S. dollar stablecoin on Optimism, Base, Ink and Unichain with more blockchains to be added next year pending regulatory review.
The dual-blockchain approach provides distinct advantages. The dual-blockchain approach allows RLUSD to serve multiple markets simultaneously. Cross-border payment providers can leverage the XRP Ledger's speed and cost efficiency, while DeFi protocols can integrate RLUSD into yield farming and liquidity provision strategies on Ethereum.
Primary Use Cases and Real-World Applications
By combining the stability of the dollar with the speed and transparency of blockchain, RLUSD is designed for use in payments, remittances, treasury flows, and on/off-ramp services within the Ripple ecosystem. Ripple has identified several use cases for RLUSD, including cross-border payments, on/off-ramps for cryptocurrency exchanges and tokenisation of real-world assets (RWA).
RLUSD enables settlements in 3–5 seconds on XRPL and Ethereum, targeting use cases like remittances, corporate treasury flows, and crypto trading pairs. RLUSD facilitates rapid, low-fee international transfers for enterprises and banks, addressing inefficiencies in traditional correspondent banking. By eliminating multiple intermediaries, RLUSD reduces both costs and settlement times, making international commerce more accessible to businesses of all sizes.
Founding Team and Project History
Ripple was founded in 2012 by Chris Larsen and Jed McCaleb. It is a provider of digital asset infrastructure for financial institutions and enterprises, focusing on streamlining global financial transactions through blockchain technology. RLUSD (Ripple USD) is a fully regulated stablecoin pegged 1:1 to the US dollar, launched by Ripple in December 2024.
Raghuram Rajan, former Governor of the Reserve Bank of India, and Kenneth Montgomery, former First Vice President and Chief Operating Officer of the Federal Reserve Bank of Boston, will join the RLUSD advisory board to provide strategic guidance on regulatory, financial, and operational aspects to support RLUSD's stability and growth. Rajan and Montgomery join the ranks of the existing advisory board including former Federal Deposit Insurance Corporation (FDIC) Chair Sheila Bair, Vice Chairman of Partners Capital and former CENTRE Consortium CEO David Puth, and Ripple co-founder and Executive Chairman Chris Larsen.
Tokenomics: Supply and Distribution
Current Supply Metrics
The current CoinMarketCap ranking is #51, with a live market cap of $1,336,039,975 USD. It has a circulating supply of 1,336,131,274 RLUSD coins. RLUSD's circulating supply surpassed $500 million within seven months of launch (July 2025).
Backing and Reserve Structure
Each RLUSD token is supported one-to-one by U.S. dollar deposits, U.S. Treasuries, and cash equivalents held in reserve. This ensures that the stablecoin maintains a consistent value equal to one U.S. dollar and can be redeemed at par. Its reserves are held at BNY Mellon, with monthly attestations ensuring transparency.
Inflation and Deflation Mechanics
Unlike traditional cryptocurrencies with fixed supplies, RLUSD operates on a demand-driven issuance model. The RLUSD stablecoin is issued when users or institutions deposit U.S. Dollars with Ripple's custodians. Each token can be redeemed 1:1 for USD. RLUSD maintains 0 RWA assets, confirming its supply remains fully USD-backed.
Consensus Mechanism and Network Security
RLUSD operates on two distinct consensus mechanisms depending on the blockchain:
XRP Ledger Consensus
At the core of XRPL's efficiency is its Proof-of-Association (PoA) consensus mechanism, previously known as the Federated Byzantine Consensus Protocol. Instead of relying on miners or staked tokens to secure the network, PoA uses a Unique Node List (UNL)—a group of trusted validators responsible for approving transactions.
The consensus process requires 80% supermajority agreement on validators' UNLs before a transaction is finalized. Any attempt to submit conflicting transactions will be spotted—since honest validators independently verify each one and vote to include only valid, non-duplicative entries in the ledger.
Thanks to this streamlined process, XRPL can handle approximately 1,500 transactions per second (TPS)—far more than Bitcoin or Ethereum—while keeping fees near zero.
Security Protections
The XRP Ledger is not vulnerable to a 51% attack because it does not use mining in its consensus mechanism. Historical data shows the XRPL has maintained extremely high uptime and network availability—with no major ledger rollbacks since launch. If consensus ever fails temporarily, the ledger does not close, so no transaction is lost; validators quickly resolve discrepancies before proceeding.
Ethereum Smart Contract Security
RLUSD's Ethereum smart contracts are audited by multiple independent firms. Ripple employs a Threat and Vulnerability Management program and a bug bounty initiative through HackerOne to maintain its security posture.
Key Partnerships and Ecosystem Integrations
Exchange Partnerships
Through strategic partnerships, RLUSD will be available globally for institutions and users on major global exchanges and platforms, including Uphold, Bitstamp, Bitso, MoonPay, Independent Reserve, CoinMENA, and Bullish.
Institutional Custodian Partnership
Ripple announced it has selected The Bank of New York Mellon Corporation (BNY), a global financial services company, for the primary custody of Ripple USD (RLUSD) reserves. BNY will serve as the primary reserve custodian of RLUSD, leveraging its deep technology stack and expertise enabling the digital assets ecosystem. In addition, BNY will provide its leading transaction banking services to underpin RLUSD's operations and deliver integrated solutions.
RippleNet Integration
Ripple's existing partnerships with 300+ financial institutions via RippleNet give RLUSD built-in adoption pathways, such as liquidity for Ripple's recently launched treasury management platform. Ripple's robust payment network covers over 90 markets, representing more than 90% of daily FX volume, and has facilitated over 37 million transactions worth nearly $70B.
Strategic Acquisitions
In April 2025, Ripple acquired prime brokerage firm Hidden Road for $1.25 billion. The acquisition aims to strengthen Ripple's position in bridging traditional finance and digital assets, controlling key transaction rails, leveraging the XRP Ledger (XRPL) for institutional services, and integrating RLUSD.
Competitive Advantages and Unique Value Proposition
Regulatory Compliance Leadership
RLUSD operates under a New York Department of Financial Services limited-purpose trust company charter, considered the gold standard for stablecoin regulation. This regulatory framework requires strict oversight of reserve assets and operational practices, providing institutional clients with confidence that many other stablecoins cannot match.
Ripple has applied for an OCC charter, which would ultimately provide RLUSD with both state and Federal oversight—a dual regulatory structure that no stablecoin currently holds.
Enterprise-Grade Design
Unlike many stablecoins that prioritize rapid market adoption, RLUSD was built with compliance, transparency, and institutional trust as core design principles. Unlike stablecoins geared primarily toward retail users, RLUSD has been purpose-built for enterprise utility, particularly in improving the speed, cost and efficiency of cross-border payments.
Market Position
RLUSD's Mcap of $1.02 billion is small compared with USDT ($169 billion) and USDC (~$72 billion). However, RLUSD posted ~1,278% YTD market-cap growth, significantly ahead of many competitors.
Transparency and Attestations
Ripple has committed to regular attestations and audits of these reserves to provide transparency and build trust in RLUSD's stability. Ripple commits to providing monthly reserve attestations conducted by independent certified public accountants. These attestations will detail RLUSD's reserve holdings, tokens minted and burned, and the circulating supply.
Current Development Activity and Roadmap
Multi-Chain Expansion
Testing will begin on Optimism, Base, Ink, and Unichain, in partnership with Wormhole—one of the leading multichain interoperability protocols—and its NTT token standard. Leveraging Wormhole's Native Token Transfers (NTT) standard allows Ripple to maintain native issuance and control of RLUSD while providing the security and flexibility of onchain liquidity movement across these new ecosystems.
Institutional Adoption Initiatives
Interactive Brokers plans to add RLUSD for 24/7 account funding. These deposits will auto-convert to USD, aiming to cut cross-border wire delays from days to minutes.
Ecosystem Growth
Further expanding XRPL's institutional offerings, Ripple has partnered with Ondo Finance to bring tokenized U.S. Treasuries (OUSG) to the XRPL. By introducing RLUSD, XRPL strengthens its competitive position among major blockchain networks, making it more appealing to financial institutions, enterprises, and liquidity providers looking for a secure and scalable on-chain settlement solution.
