Ripple and Immunefi kicked off a global “Attackathon” today, inviting white-hat hackers to break the proposed XRPL lending protocol before it ever reaches production. The program starts now with training and moves to live exploitation later this month. Ripple set a $200,000 reward pool to surface critical issues fast.
What launched today: a focused security sprint
Ripple and Immunefi opened registrations and began an education phase for security researchers on Monday, October 13, 2025. The goal is simple: find vulnerabilities in the proposed native lending protocol for the XRP Ledger (XRPL).
The partners describe the effort as an “Attackathon,” a competitive format that trains participants on the codebase, then scores real findings against a published scope. It formalizes review ahead of any validator process.
Coverage across industry outlets confirms the launch timing and the $200,000 rewards, underscoring Ripple’s push to de-risk lending at the protocol layer rather than relying only on app-level guards.
How the program works: training now, exploits later
According to materials shared with reporters, the education phase starts today so researchers can learn the architecture and constraints. This maximizes the quality of later submissions.
After training, the bug-hunting window opens with bounties for issues that could impact core safety, liquidation logic, or collateral handling in the lending design. Immunefi will triage, score, and route valid reports.
This staged approach mirrors past DeFi hardening efforts: teach the stack, then pay for proofs of risk. For XRPL, it front-loads scrutiny before any validator votes on lending features.
Why it matters: de-risking XRPL’s lending roadmap
Ripple has flagged native lending as a centerpiece of XRPL’s institutional DeFi push, alongside privacy tooling. A dedicated attackathon signals that security will set the pace.
Putting $200,000 on the table aligns incentives for independent researchers and should surface edge-case failures that formal audits might miss. That reduces the chance of logic exploits once lending moves toward activation.
Today’s launch does not change XRP price action; it targets code quality and operational readiness. The next notable date is the bug-bounty window, which follows this training phase later in October.
WisdomTree Files Second Amendment for XRP ETF Registration
WisdomTree filed Amendment No. 2 to its Form S-1 for the proposed WisdomTree XRP Fund on October 10, 2025, marking a fresh step in the spot XRP ETF race. The filing appeared in the U.S. Securities and Exchange Commission’s EDGAR database under file number 333-283538. The document lists Ryan M. Louvar as the primary contact at WisdomTree Digital Commodity Services, LLC, with legal copies sent to Morgan, Lewis & Bockius LLP in Pittsburgh.
The amendment updates earlier submissions from December 2024 and May 2025. It signals that WisdomTree is actively refining its registration in line with SEC feedback. This keeps the fund’s application active ahead of key decision windows later in October, when several spot XRP ETF proposals face deadlines. The timing aligns with broader regulatory momentum following recent listing-standard changes for commodity-based trust shares.
Spot XRP ETFs remain unapproved, but the filing indicates continued engagement between WisdomTree and the SEC. The amendment’s publication means the application is still live in the review queue. Any eventual approval would be reflected in subsequent SEC orders or accelerated effectiveness notices, but today’s move confirms the fund’s updated S-1/A is officially on record.
Analyst Flags XRP “Bounce Setup” on Intraday Chart
An analyst Kamran Asghar (@Karman_1s) highlighted a potential bounce setup on XRP/USDT 1-hour Binance chart. The shared image shows price pulling back toward a marked support zone near a rising dashed trendline. The annotated path outlines a brief dip into support, a stabilization phase, and then a continuation higher.
The chart emphasizes structure over headlines. First, it frames the green band as a retest area where buyers previously defended. Next, it traces higher lows along the ascending guide, suggesting momentum remains intact while that line holds. Finally, it sketches a zigzag consolidation that preserves the trend before any attempt at higher levels.
The post’s message is straightforward: trend support matters. If price respects the support band and the rising line, the setup favors a bounce. However, if candles break below both, the idea loses validity and the path changes. In news terms, the signal is conditional, not a call.
Analyst Maps $8–$12 XRP Target Using Fibonacci Extensions
Cryptoinsightuk outlined a bullish roadmap after the latest liquidation wick, posting a daily XRP chart from Coinbase and Binance with Fibonacci extensions. He marked a de-leveraging zone at $8–$12, citing the 2.618–4.236 extensions as potential objectives if trend momentum resumes. The chart also preserves the prior cycle high near $3.69 as the first major ceiling that price must clear before higher targets become relevant.
He explained the mechanics: if XRP reclaims and holds key retracement levels—0.618 (~$2.56), 0.702 (~$2.82), 0.786 (~$3.07)—the path opens toward extension waypoints such as 1.618 (~$5.49), then 2.618 (~$8.41), and beyond. Conversely, losing the mid-range fibs or failing to close above the $3.07–$3.69 band would weaken the extension case. The chart’s RSI (~45) signals neutral momentum, so follow-through matters more than a single spike.
Context helps. The projection treats the sell-off as a reset, not a trend break, and assumes returning demand can drive a measured advance through historical resistance. Therefore, confirmation hinges on sustained closes back above $2.82 and $3.07, rising spot volume, and defense of the $2.32–$2.56 retracement area. If those conditions hold, the $5.49 → $8.41 → $11.33–$13.16 ladder becomes a working roadmap; if not, the scenario delays.
