TLDR

  • Ripple and Immunefi are hosting a $200,000 Attackathon from October 27 to November 29 to find vulnerabilities in the new XRPL Lending Protocol
  • Security researchers will examine over 35,000 lines of C++ code and earn rewards in RLUSD stablecoin for discovering bugs
  • The XRPL Lending Protocol introduces fixed-term, uncollateralized loans for institutions without smart contracts or wrapped assets
  • An education phase is already active through XRPL Attackathon Academy, offering live sessions with Ripple engineers and developer resources
  • The protocol is in final development stages and will be voted on by XRPL validators this month for potential deployment in early 2026

Ripple has partnered with Immunefi to launch a $200,000 bug bounty program for its upcoming XRP Ledger Lending Protocol. The Attackathon will run from October 27 to November 29, inviting security researchers worldwide to examine the protocol’s code.

Participants will review over 35,000 lines of C++ code to identify potential security vulnerabilities. Rewards will be paid in Ripple’s stablecoin, RLUSD, based on the severity of bugs discovered.

An educational phase is already underway through the XRPL Attackathon Academy. The program provides hands-on guidance, live sessions with Ripple engineers, and test environments for participants.

Jasmine Cooper, Ripple’s director of product, said the partnership with Immunefi allows the company to work with top security researchers. The goal is to strengthen XRPL’s DeFi infrastructure before developers begin building on the protocol.

The initiative is part of Ripple’s institutional DeFi roadmap announced last month. The company aims to ensure financial institutions can safely use the lending protocol when it launches.

Understanding the XRPL Lending Protocol

The XRPL Lending Protocol introduces fixed-term, uncollateralized loans directly on the XRP Ledger. Unlike typical DeFi lending platforms, it avoids smart contracts and wrapped assets.

Credit assessments occur off-chain, allowing institutions to apply their own risk models. However, funds are pooled and managed on-chain to maintain transparency and security.

The protocol is governed by the new XLS-66 standard. This design represents Ripple’s effort to bring traditional credit markets into the blockchain space.

Institutions that prefer collateralized loans can structure them through regulated custodians. This approach blends blockchain efficiency with institutional trust requirements.

Cooper previously stated that the XRP Ledger has tens of thousands of XRP holders who currently lack opportunities to earn yield. The lending protocol aims to unlock this untapped asset base.

Bug Bounty Details and Security Focus

The Attackathon carries a total reward pool of $200,000. If at least one valid bug is reported, the full amount will be distributed among participants.

If no major vulnerabilities are found, a fallback pool of $30,000 will be shared with researchers who provided valuable insights. Priority targets include liquidation logic, interest accrual, and access control systems.

The most impactful discoveries will involve vulnerabilities that could affect vault solvency or asset safety. Ripple and Immunefi have identified these as critical areas requiring thorough examination.

Bug bounty programs are a common method for developers to crowdsource security testing. Projects post their code publicly and offer cash rewards to those who identify weaknesses.

Code bugs have previously cost DeFi protocols billions of dollars. In May, Cetus, Sui’s largest decentralized exchange, lost an estimated $223 million in a hack.

In 2023, a hacker exploited a code bug in lending protocol Euler to steal $197 million. The funds were later returned by the hacker.

The XRP Ledger experienced a security breach in April. A hacker compromised software used by developers, implanting code designed to steal private keys.

In August, blockchain research firm Kaiko gave the XRP Ledger a security rating of 41 out of 100. This was the lowest score among 15 blockchains analyzed.

The XRPL Lending Protocol is in its final development stages. Validators will vote on the protocol this month to decide if it will be added in a coming upgrade. If approved, the protocol could be deployed around the start of 2026.

Imagine shaping the very dialogues that define the conference, attracting an audience eager to engage with your vision. This exclusive opportunity allows you to craft an experience that directly reflects your brand’s values and objectives, away from the general hustle and bustle of the main expo floor. Unlocking Unprecedented Brand Exposure and Influence How do you ensure your message cuts through the noise? At Bitcoin World Disrupt 2025, hosting a Side Event provides unparalleled brand exposure. With over 10,000 founders, investors, and key players from the Bay Area tech ecosystem converging, your event becomes a direct conduit to a highly targeted and influential audience.

Direct Pathways to Tech Founders and Investor Connections One of the most significant advantages of hosting a Side Event is the unique access it provides to tech founders and critical investor connections. The main expo floor can be crowded, making deep, meaningful conversations challenging. Your Side Event offers an intimate, focused environment where you can engage directly with potential partners, collaborators, and funders. This direct deal flow is invaluable. You’re not just hoping to bump into the right person; you’re creating the magnet that draws them to you. This targeted interaction fosters genuine relationships, paving the way for future collaborations and investments that can propel your venture forward. What You Stand to Gain (and Lose) by Hosting a Side Event Still weighing your options? Consider the distinct advantages that come with stepping into the host’s role versus remaining an attendee. This isn’t just about visibility; it’s about strategic positioning. Benefit of Hosting a Side Event Missed Opportunity if Not Hosting Influence Where It Matters: Shape the agenda and discussions around Disrupt 2025, establishing your thought leadership. Passively consume content; miss the chance to steer critical conversations. Direct Deal Flow: Engage in focused, high-value conversations with founders and investors outside the crowded main event. Navigate a vast expo floor, competing for attention in a less intimate setting. Audience Leverage: Utilize exclusive host discount codes to bring your network directly to your event and to Disrupt. Limit your reach to organic networking within the general attendee pool. Competitive Edge: Stand out as a convener of ideas and people, differentiating your brand from the multitude of attendees. Blend into the crowd, making it harder to leave a lasting impression. Amplification with Credibility: Gain significant signal-boost from Bitcoin World, lending weight and reach to your initiative. Relinquish the powerful endorsement and promotional support of a major media platform. This stark contrast highlights that hosting is not just an added feature; it’s a fundamental shift in how you experience and benefit from Bitcoin World Disrupt 2025. It’s an investment in your brand’s future, ensuring maximum impact and return. Don’t Miss Out: Your Final Hours for Strategic Investor Connections The clock is ticking.

Hypurr NFT Floor Hits $100,000

Hypurr NFT Floor Hits $100,000

The post Hypurr NFT Floor Hits $100,000 appeared on BitcoinEthereumNews.com. The unreleased Hyperliquid NFTs’ asking price has reached six figures on permissionless OTC markets, with multiple sales above $80,000 this month. Hypurr NFTs, the official Hyperliquid NFTs, are the best-performing NFTs of 2025, and they haven’t even officially launched yet. The Hypurr collection was awarded to the perpetuals trading platform’s top 5000 accounts prior to its token launch in November 2024, and OTC desks traded the unreleased NFTs for between $30,000 and $60,000 throughout most of 2025. However, demand for the collection has skyrocketed as the HYPE token hits new highs, and the floor currently sits at $100,000 on DripTrade, a Hyperliquid-based NFT platform. Hypurr OTC Interface – Drip.Trade There have not been any six-figure sales yet, but there were five sales in September for over $80,000 per NFT, with the highest being $88,000, or roughly 1585 HYPE tokens. Speculation is the main driver behind the intense demand for the Hypurr NFTs, with buyers hoping that NFT holders will receive benefits such as additional HYPE airdrops, ecosystem token distributions, trading fee reductions, or even revenue sharing. Neither Jeff Yan, the founder of Hyperliquid, nor any of the Hyperliquid team has publicly addressed such speculation, remaining tight-lipped over any potential utility the collection may have within the Hyperliquid ecosystem. They also have not revealed why the NFTs haven’t been distributed to eligible users after almost ten months. Source: https://thedefiant.io/news/nfts-and-web3/hypurr-nft-floor-hits-usd100-000
