Ripple announced that Halborn has completed a comprehensive re‑audit of the XRPL Lending Protocol, confirming that all previously reported findings have been resolved or mitigated by the core engineering team.
Re‑audit Scope and Methodology
The security firm conducted a diff‑based review from mid‑December 2025 through January 2026, targeting code changes introduced after the protocol’s summer audit. Halborn’s analysis covered transaction validation, state consistency, parameter checks, and access‑control mechanisms, applying specification reviews, manual inspection, and automated static analysis.
By focusing on the three‑stage transaction processing model of the $XRP Ledger, the auditors ensured alignment with the XLS‑0066d standard that governs the Lending Protocol’s fixed‑term, uncollateralized loan functionality.
Findings and Security Posture
The final report identified five issues, all of which were classified below high severity and have been transparently addressed. No critical or high‑severity vulnerabilities were detected, indicating a robust security posture for the DeFi primitive.
Investors and developers can now rely on a hardened implementation, which bolsters confidence in XRP’s blockchain infrastructure and supports the broader crypto market’s DeFi ambitions.
Implications for XRP and the Market
With the re‑audit cleared, the XRPL Lending Protocol is positioned to advance decentralized finance on the XRP Ledger, potentially influencing XRP price movements as new use cases emerge. The milestone signals to investors that Ripple continues to prioritize security while expanding DeFi capabilities.
