What is the XRP Ledger lending protocol attackathon?
The XRP Ledger lending protocol attackathon is a coordinated security exercise run by Ripple and Immunefi that invites white hat researchers to probe a proposed XRPL lending protocol for critical vulnerabilities. The program combines a two‑week educational/devnet phase with an attack period (Oct 27–Nov 29) and pays up to $200,000 for validated findings.
How does the attackathon work and who can participate?
The initiative begins with a two‑week education window where researchers receive developer support, access to devnet guides, and testing environments to learn protocol specifics. After training, the formal attackathon runs from October 27 to November 29 and accepts vulnerability submissions focusing on fund safety, vault solvency, liquidation logic, interest accrual, and admin-level record integrity. Immunefi — a leading on‑chain security platform — will coordinate bounty payouts and validate findings. If at least one qualifying bug is found, the full $200,000 pool is unlocked; if none qualify, a fallback pool of $30,000 will be distributed to participants who submitted valid insights.

Why this matters for XRPL and the broader DeFi ecosystem
The proposed lending protocol aims to deliver fixed‑term, uncollateralized loans directly on the XRP Ledger without smart contracts or wrapped assets, relying instead on off‑chain credit assessment with on‑chain pooling and protocol‑enforced repayments. That design reduces certain attack surfaces but concentrates risk around off‑chain procedures and on‑chain pooling mechanisms. Given the protocol’s potential systemic impact, the attackathon is a critical step to validate liquidation mechanics, interest calculations, and administrative safeguards before a validator vote later this year.
What experts and data say
RippleX Head of Product Jasmine Cooper described the effort as part of “a broader, layered security process,” highlighting the need for community review ahead of any major amendment. Former Ripple CTO David Schwartz has previously noted the company runs a small fraction of XRPL validators, underscoring the network’s decentralized validator set. Independent research firm Kaiko placed XRPL low in a comparative security ranking in August, while security vendors CertiK, Halborn, and FYEO provided separate security reviews and endorsements—these references are reported as plain text sources for context.

Frequently Asked Questions
How much can I earn in the XRP Ledger lending protocol attackathon?
Researchers can share in a total reward pool of up to $200,000 if one or more qualifying bugs are found. If no qualifying bugs are discovered, a fallback pool of $30,000 will be distributed to participants who submitted valid insights during the program window.
When does the program start and how do I join?
The two‑week educational period precedes the attackathon. The formal attack window runs from October 27 through November 29. Interested researchers should prepare by using available devnet documentation and contacting program channels specified by Ripple and Immunefi during the education phase.
Key Takeaways
- Security‑first approach: Ripple and Immunefi are crowd‑testing the proposed protocol to reduce risks before a validator vote.
- Significant incentives: Up to $200,000 is available for valid findings, with a $30,000 fallback pool if no major bugs surface.
- Developer support and learning: A two‑week training period provides devnet guides and engineer access to broaden participation and improve submission quality.
Conclusion
The XRP Ledger lending protocol attackathon is a concerted effort by Ripple and Immunefi to stress‑test a novel uncollateralized lending design on XRPL prior to community governance. By offering strong financial incentives, an educational runway, and targeted test scopes—liquidation logic, interest accrual, and administrative controls—the program aims to surface material risks and strengthen the protocol ahead of a planned validator vote. COINOTAG will monitor outcomes and report validated findings and protocol updates as they are disclosed.
