RippleX $200K Attackathon to Secure XRPL Lending Protocol

RippleX has partnered with blockchain security firm Immunefi to launch a $200,000 Attackathon to secure the XRPL Lending Protocol. The initiative features an Academy phase from October 13–27 offering C++ tutorials, Devnet guides and direct engineer support. The bug-hunting phase runs from October 27 to November 29, 2025. Participants will probe over 35,000 lines of C++ code across core components including XLS-66 (Lending), XLS-65 (Vaults) and XLS-33 (Tokens). A full bounty is paid for critical flaws; otherwise a $30,000 fallback reward is shared among valid submissions. Rewards are paid in RLUSD, Ripple’s dollar-pegged stablecoin. By leveraging Immunefi’s network of 60,000 security experts—whose audits have secured $180 billion in funds—RippleX aims to reinforce DeFi security on the XRP Ledger before the protocol undergoes a validator vote later this year. This proactive bug bounty program is designed to identify vulnerabilities, strengthen the native XRPL Lending Protocol and boost trader confidence. At press time, XRP traded at $2.46.
