Technical FAQ

Attackathons are education-based bug hunting competitions where security researchers compete over a reward pool by submitting impactful bugs in the project's code. Here's how they work:

**Before the Attackathon**<br/> Immunefi works with the project to host a security-focused education period, providing top tier education and support to security researchers.

**During the Attackathon**<br/> Security researchers experience optimal hunting conditions, with direct project support, responsiveness, and duplicate rewards.

**After the Attackathon**<br/> Immunefi spotlights the security accomplishments with a custom leaderboard, Attackathon Summary Report, Bugfix Reviews, and Individual Achievement Cards.

Ultimately, Attackathons serve to secure projects, develop their security ecosystem, and create new opportunities for security researchers.

What's an Attackathon?

The XRP Ledger (XRPL) is a decentralized layer 1 blockchain renowned for its decade-long reliability and stability in tokenizing and exchanging crypto-native and real-world assets.

The XLS-66 specification introduces the XRP Ledger-native Lending Protocol, which facilitates straightforward, on-chain, uncollateralised fixed-term loans with pre-set interest terms. Loan liquidity is sourced from pooled funds, while the design relies on off-chain underwriting and risk management to assess borrowers’ creditworthiness.
