XRP as DeFi collateral: how Ripple’s RLUSD lending play through Flare and Morpho could reshape a $70 billion asset
Flare’s FXRP token has been approved as collateral in an institutionally curated Morpho vault on Ethereum, letting XRP holders borrow Ripple’s RLUSD stablecoin without selling. It is the first time an XRP-based asset has been accepted in a major on-chain lending market.
- Flare’s FXRP, a bridged version of XRP on Ethereum, has been approved as collateral in Sentora’s RLUSD Main vault on Morpho, allowing XRP holders to borrow Ripple’s RLUSD stablecoin without selling their tokens.
- The integration is the first time an XRP-based asset has been accepted as collateral in an institutionally curated Ethereum lending market, a milestone for an asset that has been almost entirely absent from DeFi.
- XRP is the fourth largest cryptocurrency by market capitalization at approximately $70 billion, yet its utilization in on-chain lending, borrowing, and liquidity provision has been negligible compared to assets like ETH, WBTC, and stablecoins.
- Ripple has been building RLUSD as an enterprise-focused stablecoin since August 2024, securing NYDFS approval in December 2024 and a Mastercard settlement integration in July 2026.
- The Morpho Blue lending protocol uses isolated markets designed to contain risk if problems arise with a specific collateral asset, a structure that makes it possible to onboard newer assets like FXRP without exposing the broader protocol to systemic risk.
Introduction
XRP is one of the most widely held cryptocurrencies in the world. At roughly $70 billion in market capitalization, it trails only bitcoin, ether, and Tether’s USDT. It has millions of holders, deep liquidity on centralized exchanges, and a history that predates most of the DeFi ecosystem. And yet, until this week, there was no major lending market on Ethereum where XRP holders could borrow against their position.
The reason is infrastructure, not demand. XRP runs on the XRP Ledger, a separate blockchain with its own consensus mechanism and token standard. Ethereum-based DeFi protocols cannot natively interact with XRP. To use XRP in Ethereum lending markets, someone needs to build a bridge, create a wrapped token, and convince a risk team to underwrite it. That process took years for bitcoin (resulting in WBTC), and it has now happened for XRP through Flare’s FXRP token.
On August 3, Flare announced that FXRP has been approved as collateral in Sentora’s RLUSD Main vault on Morpho. XRP holders can now convert their tokens to FXRP, bridge to Ethereum, deposit as collateral, and borrow Ripple’s RLUSD stablecoin. This is not just a technical milestone. It is a test of whether XRP can become a productive DeFi asset after years of sitting idle in wallets.
How the FXRP to RLUSD lending flow works
The process involves four steps, each handled by a different protocol.
Step one: XRP to FXRP conversion. XRP holders convert their native XRP tokens into FXRP, Flare’s bridged representation of XRP. Flare is a layer 1 blockchain that has built cross-chain data infrastructure, including the ability to create asset representations that can move between chains.
Step two: bridge FXRP to Ethereum. The FXRP token is bridged from Flare to Ethereum, where it becomes an ERC-20 token that Ethereum-based protocols can recognize and interact with.
Step three: deposit FXRP as collateral on Morpho. The Ethereum-native FXRP is deposited into Sentora’s RLUSD Main vault on Morpho Blue. Sentora, formerly known as IntoTheBlock, serves as the vault curator, meaning it reviews and approves which assets can be used as collateral. Sentora reviewed FXRP’s market behavior, oracle design, liquidity, and liquidation mechanics before granting approval.
Step four: borrow RLUSD. With FXRP deposited as collateral, the user borrows RLUSD, Ripple’s dollar-pegged stablecoin. The loan is overcollateralized, meaning the value of the FXRP deposit must exceed the value of the RLUSD borrowed. Because this is a loan against collateral and not a sale, the borrower retains exposure to XRP’s price movements.
Flare CEO Hugo Philion described the significance in terms of institutional credibility: “XRP is now collateral that an institutional risk team underwrites on Ethereum mainnet, which is a stronger form of recognition than another bridge listing.”
Why XRP has been absent from DeFi
XRP’s absence from DeFi is not accidental. It reflects three structural factors that have kept the asset isolated from the composable lending and borrowing ecosystem that Ethereum-based tokens take for granted.
Separate blockchain architecture. The XRP Ledger uses a different consensus mechanism (the XRP Ledger Consensus Protocol) and token standard than Ethereum. Unlike ERC-20 tokens, which can be natively deposited into any Ethereum smart contract, XRP requires a bridge and a wrapped representation to interact with Ethereum DeFi. Building that bridge securely takes time and auditing resources. The XRP Ledger was designed for payments, not for programmable smart contracts, which means the tooling and standards that Ethereum DeFi relies on do not exist natively on XRPL.
Regulatory uncertainty. The SEC’s lawsuit against Ripple, filed in December 2020 and not fully resolved until 2024, created a chilling effect on DeFi integration. Protocol teams and vault curators were reluctant to add XRP-based collateral when the token’s regulatory status was unclear. DeFi protocols have their own compliance considerations, and adding a token that the SEC claimed was an unregistered security was a risk most teams chose to avoid. The resolution of that case removed the legal overhang but did not immediately produce DeFi infrastructure.
Limited DeFi ecosystem on XRPL. The XRP Ledger has a built-in decentralized exchange and an automated market maker, but its DeFi ecosystem is small compared to Ethereum, Solana, or even newer L2 networks. Most DeFi activity, lending, borrowing, yield farming, and derivatives, happens on Ethereum and its rollups. For XRP holders to participate, they need to leave the XRPL, which until FXRP was not straightforward. The result is that a $70 billion asset has been almost entirely absent from on-chain credit markets, a gap that is disproportionate to its size and liquidity on centralized venues.
The WBTC parallel
The closest analogy to what Flare is doing with FXRP is Wrapped Bitcoin (WBTC), which has been operating on Ethereum since 2019. WBTC lets bitcoin holders wrap their BTC into an ERC-20 token, deposit it as collateral on Aave, Compound, and MakerDAO, and borrow stablecoins against it.
WBTC demonstrated that non-native assets can become productive DeFi collateral if the bridge is trustworthy and the lending market is deep enough. At its peak, WBTC had over $15 billion in total value locked. It proved that bitcoin holders wanted to borrow against their positions rather than sell.
FXRP aims to replicate this model for XRP. The key differences are scale (WBTC had years of liquidity building, FXRP is just launching) and custody model (WBTC relies on a centralized custodian, BitGo, while Flare uses a decentralized bridge). Whether FXRP achieves WBTC-level adoption depends on whether XRP holders are willing to bridge their tokens and whether additional lending vaults beyond Sentora add FXRP as collateral. The bridging step is a genuine friction point: WBTC holders only needed to interact with a single custodian, while FXRP holders must navigate Flare’s cross-chain infrastructure before reaching Ethereum. Reducing that friction through improved tooling and wallet integrations is as important to adoption as the lending market itself.
What RLUSD is and why it matters here
RLUSD is Ripple’s dollar-pegged stablecoin, designed for enterprise use cases including cross-border payments and institutional settlement. Ripple began testing RLUSD on Ethereum and the XRP Ledger in August 2024 and received approval from the New York Department of Financial Services in December 2024.
RLUSD is not trying to be USDC or USDT. Ripple has positioned it as a compliance-first stablecoin for regulated financial institutions. The Mastercard settlement integration announced in July 2026 is an example: Mastercard will support settlement of regulated stablecoins including RLUSD, USDC, and SoFi’s SoFiUSD. Zand Bank in the UAE began using RLUSD for cross-border payments in early 2026. Ripple has also expanded into Latin America, bringing Bitso’s Mexican peso-backed stablecoin MXNB onto the XRP Ledger in June 2026.
The FXRP/RLUSD lending integration adds a new use case: on-chain borrowing. XRP holders who want dollar liquidity without selling can now borrow RLUSD against their position. If RLUSD is accepted at more venues and payment rails, the utility of borrowing it increases. This creates a flywheel where RLUSD adoption in payments makes RLUSD borrowing more attractive, which drives more FXRP deposits, which deepens the lending market.
The stablecoin landscape itself is shifting rapidly. Circle recently brought USDC to the XRP Ledger, meaning XRPL now supports both RLUSD and USDC natively. This multi-stablecoin approach on XRPL means XRP holders have more options for accessing dollar liquidity, and the FXRP/RLUSD lending market on Ethereum adds yet another path. For Ripple, the strategic play is to make RLUSD the default borrowing currency for XRP-collateralized loans, creating a use case that USDC does not serve.
Why Morpho Blue’s isolated market design matters
Morpho Blue is a lending protocol that uses isolated markets instead of the shared pool model used by Aave and Compound. In a shared pool, all depositors share risk: if one collateral asset fails, losses can spread across the entire protocol. In Morpho Blue’s isolated markets, each collateral-borrow pair operates independently. A problem with FXRP would affect only the FXRP/RLUSD market, not other lending pairs on the protocol.
This design is what made it possible for Sentora to approve FXRP as collateral. A shared pool protocol would likely have rejected a newly bridged token with limited on-chain history. Morpho Blue’s isolation means the risk is contained, and the vault curator (Sentora) bears the responsibility for evaluating it.
Sentora’s CTO Jesus Rodriguez described the approval as a deliberate expansion of on-chain credit: “XRP is one of crypto’s largest and most liquid assets. Yet it remains surprisingly underused in onchain credit. That changes today.” The framing is significant: this is not a DeFi experiment. It is an institutional risk team making a calculated underwriting decision.
The isolation model also creates a natural price discovery mechanism for FXRP risk. Because each vault has its own interest rate curve determined by utilization, lenders are effectively pricing the specific risk of FXRP collateral rather than having that risk diluted across a shared pool. If the market perceives FXRP bridge risk as elevated, rates in FXRP-collateralized vaults will rise relative to vaults backed by native Ethereum assets. This transparency gives both lenders and borrowers real-time information about how the market values the bridge and custody mechanisms that underpin FXRP.
The $70 billion question
XRP has roughly $70 billion in market capitalization. If even 5% of that value migrates into DeFi collateral positions (as happened with bitcoin through WBTC), the result would be $3.5 billion in new collateral available for borrowing. At 10%, it would be $7 billion.
For context, Morpho Blue’s total value locked across all markets is roughly $4 billion. A meaningful flow of XRP into the protocol would make it one of the largest collateral assets on the platform. Whether this happens depends on XRP holder behavior, FXRP bridge trust, and RLUSD utility. But the infrastructure is now in place for the first time.
The peso-backed stablecoin integration on XRPL through Bitso and the USDC expansion to XRP Ledger through Circle show that Ripple is building a multi-stablecoin ecosystem around XRP. The FXRP/RLUSD lending market extends this ecosystem into Ethereum DeFi, bridging two worlds that have historically operated separately.
The comparison to Ethereum’s DeFi trajectory is instructive. When WETH first became available as collateral on Aave and Compound, it took approximately 18 months before the cumulative value locked in ETH-collateralized lending exceeded 5% of ETH’s market capitalization. XRP faces a steeper adoption curve because its holder base skews more retail, with a lower proportion of technically sophisticated users who are comfortable with bridge mechanics and vault management. The institutional channel through Sentora’s curated vaults could accelerate adoption, but institutional allocators typically require six to twelve months of live market data before committing significant capital.
What scale adoption would look like
The WBTC adoption curve provides a template for projecting what FXRP could achieve over a multiyear period. When WBTC launched in January 2019, it began with a few million dollars in total value locked. It took roughly 18 months to reach $1 billion, and another year to reach $10 billion as DeFi activity surged through 2020 and 2021. At its peak in late 2021, WBTC held over $15 billion in total value locked across Aave, Compound, and MakerDAO, representing roughly 1.5% of bitcoin’s market cap at the time.
FXRP starts from a different baseline. XRP has no DeFi history to build on, while WBTC launched when bitcoin holders already understood the concept of using cryptocurrency as collateral and had watched earlier DeFi protocols develop lending markets. But XRP’s size, $70 billion in market capitalization, means even a small adoption rate translates to significant absolute TVL. If FXRP captures 0.5% of XRP market cap in collateral, that is $350 million. At 1%, $700 million. At the WBTC peak rate of roughly 1.5%, it would be more than $1 billion.
For Morpho Blue, these numbers are material. The protocol’s total value locked across all markets is roughly $4 billion. A $500 million FXRP collateral pool would represent more than 10% of Morpho’s total market size, making FXRP a top-tier collateral asset and attracting market makers, liquidation bots, and additional vault curators who see FXRP liquidity as worth their infrastructure investment.
The institutional framing matters here. Sentora’s approval is not just a permission to participate; it is a credentialing signal. DeFi protocols are understandably skeptical of bridged assets because bridge exploits have caused billions in losses. An institutional risk team reviewing oracle design, liquidity profiles, and liquidation mechanics before granting approval lowers the barrier for the second and third curator approvals. Morpho’s isolated market architecture means curators can observe how the FXRP/RLUSD market behaves before committing their own vaults, using Sentora’s early data as evidence.
Ripple’s existing institutional relationships give FXRP a distribution channel that WBTC did not have at launch. RLUSD is already integrated with Mastercard settlement, live in Zand Bank UAE, and present on the XRP Ledger alongside USDC. If Ripple’s enterprise payment partners begin borrowing RLUSD against FXRP positions for working capital or treasury management, the institutional use case extends beyond retail speculation. A $10 million working capital facility backed by XRP collateral, accessed through the FXRP bridge and Morpho, is precisely the kind of product that Ripple’s enterprise sales network can take to existing RLUSD clients. That commercial distribution path distinguishes FXRP from purely retail-driven bridged tokens and gives the collateral market a demand source that does not depend on DeFi sentiment cycles.
The risk of bridge-based DeFi collateral
The FXRP model introduces risks that native Ethereum tokens do not carry. Every step in the flow, XRP to FXRP conversion, bridging from Flare to Ethereum, oracle pricing, and Morpho vault liquidation, represents a potential failure point.
Bridge exploits are the most expensive category of smart contract hacks in crypto history. Cross-chain bridges have caused over $4 billion in losses since 2021, including the Ronin ($624 million), Wormhole ($326 million), and Nomad ($190 million) exploits. Each of these hacks targeted the trust assumptions that allow assets to move between chains. The FXRP bridge uses Flare’s decentralized infrastructure, which is architecturally different from the compromised bridges, but the risk category is the same: any vulnerability in the bridge could result in unbacked FXRP tokens on Ethereum, which would make the Morpho collateral worthless.
Oracle risk is the second concern. The Morpho vault needs an accurate, manipulation-resistant price feed for FXRP to trigger liquidations at the right time. If the oracle diverges from the true market price of XRP, two outcomes are possible: premature liquidations that harm borrowers, or delayed liquidations that leave lenders with bad debt. Sentora reviewed the oracle design before approving FXRP, but the limited on-chain history of the token means the oracle has not been tested under extreme market conditions.
Liquidity risk is the third factor. If a borrower’s FXRP collateral needs to be liquidated, there must be sufficient FXRP liquidity on Ethereum for liquidators to sell the seized tokens. A thin FXRP market could result in liquidators being unable to recover the full value of the loan, creating losses for RLUSD lenders. This is a bootstrapping problem: liquidity improves as adoption grows, but adoption depends on liquidity being sufficient from the start.
Historical precedent suggests bridge exploits follow a pattern. The Ronin bridge lost $625 million in March 2022 when attackers compromised validator keys. The Wormhole bridge lost $320 million a month earlier through a signature verification bypass. In both cases, the underlying assets on the source chain were unaffected, but the wrapped representations on the destination chain became worthless. For FXRP holders using Morpho vaults, a Flare bridge compromise would mean their collateral evaporates while their loan obligations remain. The asymmetry between borrower and lender risk in a bridge failure scenario is one of the least discussed aspects of cross-chain DeFi collateral.
What would invalidate this thesis
The bullish read is that FXRP opens a new chapter for XRP in DeFi. The bearish read is that XRP holders have shown little interest in DeFi historically, and a bridged token on an unfamiliar protocol will not change that behavior.
If FXRP deposits remain below $50 million after six months, the integration was a technical success but a commercial failure. If the FXRP bridge suffers a security incident, trust in the model collapses. If RLUSD itself fails to gain traction beyond a few institutional partnerships, the borrowing side of the market dies. And if XRP’s price drops significantly, FXRP collateral positions get liquidated, creating negative feedback loops that discourage further deposits.
Regulatory risk adds another dimension. If regulators classify FXRP as a derivative or synthetic asset rather than a direct representation of XRP, the compliance burden on institutional vaults could make the product uneconomical. The SEC has not issued guidance on wrapped or bridged tokens as a distinct category, and enforcement actions in adjacent areas suggest the regulatory framework remains uncertain. A single enforcement action against a bridged asset product could freeze institutional participation across the entire category.
What to watch
FXRP total value deposited on Morpho. The single most important metric. If deposits reach $500 million within six months, XRP holders are adopting DeFi collateral use cases. If deposits stall below $100 million, adoption has failed.
RLUSD circulating supply growth. Track whether the lending integration drives new RLUSD minting. If borrowing demand increases RLUSD supply, the flywheel is working.
Additional vault curators adding FXRP. Sentora is the first. If other curators like Gauntlet, Block Analitica, or Steakhouse Financial add FXRP vaults, the collateral is gaining broader institutional acceptance.
Flare bridge security. Any exploit or significant downtime on the FXRP bridge would damage trust in the model. Track audit reports, bridge volume, and incident history.
XRP DeFi TVL relative to market cap. Currently near zero. Bitcoin’s WBTC TVL as a percentage of BTC market cap reached roughly 1.5% at peak. If FXRP reaches even 0.5% of XRP market cap ($350 million), it would represent meaningful DeFi adoption.
Frequently asked questions
What is FXRP?
FXRP is Flare’s bridged version of XRP that operates as an ERC-20 token on Ethereum. It allows XRP holders to use their tokens in Ethereum-based DeFi protocols without selling the underlying XRP.
What is RLUSD?
RLUSD is Ripple’s dollar-pegged stablecoin, designed for enterprise use cases including cross-border payments and institutional settlement. It was approved by the New York Department of Financial Services in December 2024 and launched on Ethereum and the XRP Ledger.
How does XRP lending on Morpho work?
XRP holders convert XRP to FXRP on Flare, bridge FXRP to Ethereum, deposit it as collateral in Sentora’s RLUSD vault on Morpho Blue, and borrow RLUSD against their position. The loan is overcollateralized and retains the borrower’s exposure to XRP price movements.
Why has XRP been absent from Ethereum DeFi?
XRP runs on a separate blockchain (the XRP Ledger) that cannot natively interact with Ethereum smart contracts. The SEC lawsuit against Ripple also discouraged DeFi protocol teams from integrating XRP-based assets until the case was resolved.
What is Morpho Blue?
Morpho Blue is a lending protocol that uses isolated markets instead of shared pools. Each collateral-borrow pair operates independently, containing risk and making it possible to onboard newer assets like FXRP without exposing the broader protocol.
How is FXRP different from WBTC?
Both are bridged representations of non-Ethereum assets. WBTC uses a centralized custodian (BitGo) to hold the underlying bitcoin, while FXRP uses Flare’s decentralized bridge. WBTC has years of liquidity history and widespread DeFi integration; FXRP is just launching.
What is Sentora’s role?
Sentora (formerly IntoTheBlock) is the vault curator that reviewed and approved FXRP as collateral for the RLUSD lending market on Morpho. Curators evaluate collateral assets for market behavior, oracle design, liquidity, and liquidation mechanics before granting approval.
Could this model expand to other assets?
Yes. The FXRP/Morpho model could be replicated for other non-Ethereum assets that have large market capitalizations but limited DeFi presence. The success or failure of the FXRP integration will likely influence whether curators approve similar bridged tokens in the future.
