Uncollateralized loans on XRP Ledger bring new DeFi opportunities. $200,000 reward pool for identifying security vulnerabilities in protocol. XRPL Lending Protocol aims to reshape institutional finance and security. Ripple and Immunefi have unveiled an exciting opportunity in the world of blockchain security with a $200,000 Attackathon aimed at securing the proposed XRPL Lending Protocol. This competition seeks to enhance the protocol’s security by inviting security researchers to dive deep into its code, identifying vulnerabilities before the protocol goes live. The Attackathon, which will run from October 27 to November 29, 2025, offers a unique opportunity to test and fortify a groundbreaking new protocol designed for institutional use.

It introduces a new approach to institutional DeFi, where creditworthiness is assessed off-chain using traditional underwriting and risk models. The protocol’s design emphasizes security by allowing funds to be pooled on-chain while enforcing predefined terms for repayments. Institutions looking for collateralized loans can still rely on off-ledger structures, ensuring a balance between transparency and regulatory compliance. We are collaborating with @immunefi to prepare a $200K Attackathon to test and strengthen the proposed XRP Ledger Lending Protocol. The program runs Oct 27 – Nov 24 and invites security researchers to review more than 35K lines of C++ code, uncover vulnerabilities, and earn… https://t.co/eQ4wTtsSCt — RippleX (@RippleXDev) October 13, 2025 According to Ripple and Immunefi, this competition is more than just a security exercise. It serves as a foundational step in the development of capital markets on the XRP Ledger. The contest will focus on a series of critical areas, including liquidation logic, interest accrual, clawback, deepfreeze, and administrative attacks. Researchers will be expected to submit proof-of-concept exploits to qualify for rewards. The main goal is to ensure that the protocol can stand up to adversarial scrutiny, mitigating risks that could impact institutional users. XRPL Attackathon’s Structure and Key Targets The competition offers a total reward pool of $200,000, which will be unlocked if even a single valid bug is identified. If no bugs are found, a fallback reward pool of $30,000 will be distributed among participants who submit valid insights. Participants will have the chance to showcase their expertise in identifying flaws related to the protocol’s liquidation logic, interest accrual errors, or weaknesses in permissioned access controls. Additionally, Immunefi’s All Star and Podium programs will reward top performers, ensuring that the most skilled security researchers are recognized for their efforts. The competition is open to developers familiar with C++ and will include live walkthroughs and a comprehensive XRPL-focused curriculum to support participants. Ripple and Immunefi aim to make this a collaborative effort, offering full access to test environments and providing policy support via Discord for ongoing coordination. The XRPL Lending Protocol, governed by XLS-66, marks a bold step in the future of decentralized finance, particularly for institutional players. As Ripple and Immunefi gear up for the Attackathon, the stakes are high. This collaboration promises not only to strengthen XRPL’s security but also to pave the way for more sophisticated and secure financial solutions on the blockchain.
