TL;DR:
- The security analysis was executed by the firm Halborn between mid-December 2025 and January 2026.
- The technical audit concluded with zero vulnerabilities classified in the critical or high severity ranges.
- Ripple’s technical team resolved all five specific findings detailed in the technical report.
The security re-audit of the XRP lending protocol was successfully completed for Ripple. This step represents a major technical milestone for the deployment of decentralized finance (DeFi) capabilities within the XRP Ledger (XRPL) network.
The codebase review was conducted by the Web3 security firm Halborn. The firm’s official report reveals that Ripple’s engineers resolved or strategically managed all observations identified in previous assessments.

Technical details and resolution of vulnerabilities
Between December 2025 and January 2026, a review was conducted consisting of a diff-based audit. The analysis focused explicitly on the source code modifications introduced after the initial audit conducted the previous summer.
The procedure aimed to validate the security of the implementation against the XLS-0066d technical specification. Engineers examined transaction validation logic, network state consistency, parameter checks, and system access controls.
Halborn employed a layered structured analytical approach. Thanks to this methodology, they were able to conduct specification reviews, code diff analysis, manual inspection, and automated static analysis to evaluate XRPL’s three-stage transaction processing model.
The auditing firm’s final report recorded no high or critical severity vulnerabilities. The document detailed a total of five minor findings, which were transparently resolved or accepted by the developers.
One of the corrected points corresponded to a missing validation that allowed a vault’s total assets to exceed the maximum configured limit through the accumulation of loan interest. Ripple confirmed that this bug was fixed internally before the formal audit process began.
Likewise, the auditors detected that users theoretically possessed the ability to create a LoanBroker on a frozen vault, which would have caused the unnecessary expenditure of reserve funds on an inoperative configuration. The Ripple team corrected this scenario by adding a freeze check in the transaction’s pre-claim (preclaim) stage.
With the definitive closure of these technical reports, the development of the decentralized lending environment clears its primary computer infrastructure barrier. The next scheduled milestone within the network’s roadmap consists of the amendment vote by validators to enable the code on the main network.
