What changed
Web3 security firm Halborn completed a diff-based re-audit of the XRPL Lending Protocol between mid-December 2025 and January 2026, focusing on changes since the prior audit. The review assessed transaction validation, state consistency, parameter checks, and access controls, and confirmed the updated codebase aligns with XLS-0066d. Source. The re-audit concluded with zero critical or high-severity vulnerabilities remaining. The five findings identified were addressed or accepted by RippleX engineers before deployment.
The audit and fixes underscore a formal, multi-party security process around XRPL’s native lending primitives, reinforcing the standard-set approach for on-ledger financial primitives. The collaboration involved engineering review and verification of the code changes against the XLS-0066d specification.
What the episode exposed
The episode underscores a disciplined security cadence for DeFi primitives on XRPL: a diff-based re-audit followed by targeted fixes before mainnet deployment. Among the five findings, a critical issue was resolved by adding a missing validation check that could have allowed a vault’s total assets to exceed its configured maximum through interest accumulation, and a freeze-check was added to the LoanBroker preclaim stage to prevent creating a LoanBroker on a frozen Single Asset Vault, protecting reserve requirements. This progress is accompanied by public indications of Halborn’s work and RippleX’s engineering response. The broader takeaway is that such audits, bug-bounty activity, and formal re-audits form a safety backbone for native DeFi on XRPL, even as the codebase continues to evolve. The ongoing vigilance implied by five findings being addressed highlights that security is an evolving discipline rather than a one-off box-ticking exercise.
