**Ripple and Immunefi Launch $200,000 Attackathon to Secure Upcoming XRPL Lending Protocol**

Ripple has partnered with Immunefi to announce a $200,000 bug bounty event called **Attackathon**, designed to test and secure the upcoming XRP Ledger (XRPL) Lending Protocol ahead of its official launch. The competition will run from **October 27 to November 29**, inviting ethical hackers and security researchers to identify vulnerabilities before the protocol goes live.

### White-Hat Hackers Invited to Test XRPL Lending Protocol

The XRPL Lending Protocol aims to offer fixed-term, uncollateralized loans on the XRP Ledger. Governed under the XLS-66 standard, the system assesses borrower risk off-chain and operates without relying on smart contracts or on-chain collateral, diverging from traditional DeFi models. Ripple intends this approach to encourage greater institutional adoption by combining off-chain credit evaluation with ledger-based settlement.

Ripple and Immunefi have opened the bug bounty competition to white-hat hackers, offering a reward pool of $200,000 for reproducible, valid exploits. Immunefi will manage the submission process, verify findings, and rank vulnerabilities based on their potential impact on protocol security—focusing particularly on areas such as vault logic, liquidation mechanisms, interest calculations, and access controls.

### Attackathon Academy: Technical Support and Learning Program

Before the bug-hunting phase begins on October 27, Ripple will run the **Attackathon Academy** from October 13 to October 27. This educational program is designed to help participants familiarize themselves with the XRPL Lending Protocol’s architecture. The Academy will provide extensive documentation, technical walkthroughs, and access to a Devnet testing environment to empower researchers in crafting high-quality submissions.

### Bounty Rewards and Criteria

The full $200,000 reward pool will be unlocked only if major exploitable vulnerabilities are found. If no critical bugs are identified, Ripple will still distribute $30,000 among contributors who submit meaningful security insights. To qualify for rewards, all submissions must include reproducible bugs accompanied by working proof-of-concepts.

Immunefi will oversee the transparency and security of the bounty process, ensuring that all activities are conducted fairly and efficiently.

### Protocol Integrates Multiple XRPL Standards

The new lending protocol incorporates several XRP Ledger standards to enable comprehensive functionality. These include:

– **XLS-65**: Vault management
– **XLS-33**: Token handling
– **XLS-70**: Credential management
– **XLS-80**: Domain permissions

All associated modules are within the scope of the security challenge. Participants are encouraged to test interactions across these layers to uncover any hidden risks that could impact the protocol’s safety and reliability.

### Ripple’s Commitment to Security

Ripple’s collaboration with Immunefi highlights its commitment to robust security practices ahead of the XRPL Lending Protocol’s launch. By proactively inviting the global security community to vet the protocol, Ripple aims to ensure a safe and trustworthy lending ecosystem that meets institutional standards.
