XRP News Today: Securing the Future of Institutional DeFi: Ripple and Immunefi's $200K Attackathon

Ripple and Immunefi have launched a $200,000 "Attackathon" to rigorously test the security of the XRP Ledger (XRPL) Lending Protocol, a key initiative in expanding institutional-grade decentralized finance (DeFi) on the blockchain. The event, announced on October 13, 2025, involves a global network of security researchers tasked with identifying vulnerabilities in the protocol before its potential deployment later this year. The Attackathon is structured as a time-boxed adversarial competition, with a two-phase approach: an educational period from October 13 to 27, followed by active bug hunting from October 27 to November 29 Ripple and Immunefi Launch Attackathon to Protect XRPL Lending Protocol^[1].

The XRPL Lending Protocol, governed by the XLS-66 standard, aims to introduce fixed-term, uncollateralized loans directly on the XRP Ledger. Unlike traditional DeFi models reliant on smart contracts or collateral, this protocol leverages off-chain credit assessments while automating loan issuance, repayment, and liquidity pooling on-chain. The initiative is designed to enable financial institutions and developers to streamline loan workflows while connecting borrowers to global liquidity and allowing lenders to earn returns on idle assets Ripple and Immunefi Launch $200K XRPL Attackathon^[3].

Immunefi, a leading on-chain security platform protecting $180 billion in user funds, is collaborating with Ripple to ensure the protocol meets stringent security standards. The partnership taps into Immunefi's community of over 60,000 researchers, who have previously prevented $25 billion in hacking attempts across 650+ protocols. The Attackathon's reward structure incentivizes researchers to uncover critical flaws, with the full $200,000 prize pool distributed if valid vulnerabilities are identified. A $30,000 fallback pool is reserved for participants who submit valuable insights if no major bugs are found XRP News Today: Ripple Launches $200K Attackathon to Test^[4].

Ripple emphasized the importance of pre-launch testing, citing Jasmine Cooper, product lead at RippleX, who stated that the initiative ensures the protocol is "thoroughly tested and resilient" before deployment. The collaboration aligns with Ripple's broader institutional DeFi roadmap, which includes features like tokenized assets, compliance tools (e.g., Deep Freeze for sanction-compliant transfers), and zero-knowledge proofs (ZKPs) for privacy-preserving transactions Ripple and Immunefi launch 'Attackathon' aimed at securing^[5].

The protocol is expected to undergo a validator vote by year-end, with potential adoption by financial institutions seeking scalable, secure lending infrastructure. Immunefi's CEO, Mitchell Amador, highlighted the initiative's role in reinforcing XRPL's infrastructure and advancing Immunefi's mission to protect critical Web3 ecosystems Immunefi, Ripple launch security competition for XRPL lending^[13].
