Ripple Researchers Propose Privacy-Preserving Transfers for XRPL Multi-Purpose Tokens

Published

on

The Ripple research team has published a paper on adding transaction privacy to the XRP Ledger (XRPL). 

The paper introduces Confidential Transfers for Multi-Purpose Tokens (Confidential MPTs). The goal is to enable institutional and regulated use cases, with issuer controls such as freezing and clawbacks.

The paper is authored by Murat Cenk, Aanchal Malhotra, and Joseph Ayo Akinyele. The Confidential MPTs would be a cryptographic extension of the XLS-33 token standard, which went live on the XRPL mainnet in October 2025

The protocol replaces plaintext per-account balances with EC-ElGamal ciphertexts. Furthermore, it uses non-interactive zero-knowledge proofs to enforce transfer correctness and balance sufficiency without requiring decryption by validators. 

Meanwhile, sender and receiver identities remain visible, preserving XRPL’s account-based model

“To accommodate regulatory and institutional requirements, Confidential MPTs provide cryptographic auditability through an on-chain selective-disclosure model based on multi-ciphertext balance representations and equality proofs, while remaining compatible with simpler issuer-mediated audit models,” the abstract reads.

The timing aligns with shifting regulatory attitudes toward on-chain privacy. In a recent report submitted to Congress in early March, the US Treasury Department acknowledged that lawful users of digital assets may rely on mixers when transacting on public blockchains.

The privacy paper arrives as Ripple simultaneously strengthens the network’s security foundation. The firm recently outlined an AI-driven security strategy for XRPL.

Brent Surges 5% on Hormuz Crisis

Brent Surges 5% on Hormuz Crisis

Oil price news Monday showed Brent crude jumped 4.3% to $94.18 and WTI rose 5.6% to $88.54, reversing Friday’s 9% collapse as Iran reimposed Strait of Hormuz restrictions over the weekend, the US Navy seized the Iranian cargo vessel Touska, and Kpler maritime data recorded zero tanker crossings of the strait on Sunday.

Summary

  • Iran’s IRGC fired on two vessels attempting to transit Saturday before declaring the strait closed until the US lifts its naval blockade.
  • The USS Spruance fired several rounds at the Touska after it ignored six hours of warnings, then US Marines boarded and took custody of the ship.
  • Iran’s Foreign Ministry said Monday it has “no plans” for the Pakistan talks, leaving the ceasefire that expires Wednesday without a diplomatic path forward.

Oil price news opened the week with a sharp reversal of Friday’s optimism. Iran’s foreign minister had announced Friday that the Strait of Hormuz was completely open, sending Brent crude crashing 9%. By Saturday, Iran had reimposed restrictions, its gunboats were firing on tankers, and by Sunday the US had seized an Iranian-flagged cargo ship in the Gulf of Oman. The physical market confirmed the reversal: Kpler data recorded no oil tankers crossing the strait on Sunday.

The strait normally carries roughly 20% of the world’s oil and liquefied natural gas. ADNOC CEO Sultan Al Jaber put the cumulative supply loss at nearly 600 million barrels over approximately 50 days of the crisis, a figure that does not normalize quickly even under a genuine ceasefire.

“Markets are trading in a world where there is plenty of spin, statements, and speculation, but very little information of substance,” UBS Global Wealth Management chief economist Paul Donovan wrote in a Monday morning note. “Events over the weekend have reversed some of that optimism.”

Iran announced Saturday it was reimposing restrictions on the strait, accusing the US of failing to lift its naval blockade despite the April 8 ceasefire terms. IRGC gunboats fired on two India-flagged vessels attempting to transit. The UK Maritime Trade Operations Centre reported a tanker approached and fired upon with no prior radio warning.

The US Navy destroyer USS Spruance fired several rounds from its 5-inch gun at the Iranian-flagged cargo vessel Touska on Sunday after the ship ignored six hours of warnings to comply with the blockade. US Marines then rappelled from helicopters and took custody of the vessel. Trump announced the seizure on Truth Social, calling it a situation that “did not go well for them.”

Iran’s military called the seizure “maritime piracy” and warned retaliation would follow once the safety of the crew and their family members aboard was confirmed.

The Market’s Read and What Comes Next

The ceasefire expires Wednesday. Iran has declared it has no plans to attend a second round of Pakistan talks. The US delegation led by Vice President JD Vance is heading to Islamabad regardless. That asymmetry, Washington traveling for talks while Tehran publicly refuses to show up, defines the next 48 hours as the highest-risk window since the original ceasefire was struck.

Wholesale gasoline prices rose over 3% Monday and heating oil futures, a proxy for jet fuel, spiked 4%. S&P 500 futures fell 0.5% while Nasdaq futures dropped 0.6%, signaling that energy-driven inflation fears are once again bleeding into broader equity risk pricing.

For oil bitcoin dynamics, Monday’s Brent print at $94 returns crude to the level where oil inflation expectations begin to suppress Federal Reserve rate cut prospects and compress risk appetite simultaneously. Tracking prior week sessions shows that each Hormuz escalation has produced a progressively smaller BTC drawdown, suggesting institutional demand is absorbing the selling pressure even as the macro headwind persists.

Aave Pitches Two Solutions to Resolve Kelp DAO Hack Dilemma

Aave Pitches Two Solutions to Resolve Kelp DAO Hack Dilemma

Decentralized lending platform Aave’s risk management provider has outlined two scenarios on how bad debt from the Kelp DAO exploit over the weekend could impact the ecosystem, depending on how the losses are allocated.

The incident began on Saturday when hackers stole 116,500 Kelp DAO Restaked ETH (rsETH) tokens worth $293 million from Kelp DAO’s LayerZero-powered bridge and used them as collateral on Aave V3 to borrow wrapped Ether (wETH).

On Monday, LlamaRisk modeled two possible scenarios for how this “bad debt” could materialize on Aave, noting that the final decision rests with Kelp DAO.

The incident highlights the contagion risk in DeFi, where a single bridge exploit can trigger liquidity crunches and mass withdrawals across interconnected protocols like Aave, which has seen nearly $10 billion in value leave the protocol since the Kelp DAO exploit took place.

Two scenarios and potential paths forward

The first scenario would see losses spread across all rsETH token holders on Ethereum mainnet and Ethereum layer 2s, resulting in roughly $123.7 million of bad debt on Aave while risking a 15% depeg in rsETH relative to Ether (ETH).

LlamaRisk said this first scenario would spread losses more thinly across all chains, while noting that wrapped Ether (wETH) would be “absorbing the bulk in absolute terms but barely noticing it relative to its reserve depth.”

Aave could also use its Umbrella security model to cover losses in wETH under the first scenario, noting that 18,922 Aave Wrapped ETH (aWETH) tokens worth nearly $43.7 million have entered the unstaking cooldown phase.

The second scenario would shift the entire shortfall to Ethereum layer 2 networks, such as Arbitrum and Mantle. However, the bad debt would be significantly higher at $230.1 million.

LlamaRisk also noted that Aave has around $181 million in its treasury that could be used to address a potential bad debt shortfall.

On Monday, Kelp DAO said it is still assessing the financial impact of the exploit and how to safely unpause the protocol, adding that it is working with Aave, LayerZero and other stakeholders on a path forward.

Kelp DAO sheds more light on the exploit

Kelp DAO also shared more details about the incident, saying that two nodes tied to the LayerZero bridge were compromised, while a third was hit with a distributed denial-of-service attack.

The attacker forged a seemingly valid transfer message that the system approved, allowing 116,500 rsETH to be minted on one of LayerZero’s bridges.

Kelp said it paused all relevant contracts on Ethereum and Ethereum layer 2s and blacklisted all wallets tied to the exploiter shortly after, preventing them from stealing another 40,000 rsETH worth $95 million.
