Key Takeaways:
The XRP Ledger Lending Protocol passed a Halborn re-audit with zero critical or high-severity vulnerabilities in the reviewed codebase.
"We are proud to share that we have completed our XRP Ledger Lending Protocol Re-Audit for Ripple," Halborn said in its report, which covered code changes made between Dec. 16, 2025, and Jan. 12, 2026.
The re-audit identified five issues — zero critical, zero high-risk, one medium, two low and two informational — with all findings addressed by Ripple's engineering team. The medium issue, involving a vault assets maximum bypass through loan interest, was marked as solved. The scope covered transaction validation, vault limits, access controls and core functions tied to the XLS-0066d lending standard.
The protocol is designed around fixed-term, uncollateralized loans backed by off-chain underwriting and pooled liquidity held in Single Asset Vaults — a structure that differs from overcollateralized models common in DeFi on Ethereum. The feature is tied to an amendment currently under validator voting on XRPL, meaning the audit result strengthens the case for mainnet deployment but does not guarantee approval.
Ripple executive Reece Merrick confirmed the development, triggering excitement across the XRP community. SOIL, a protocol offering institutional lending services with USDC, RLUSD and XRP, has announced plans to become the first application to use the XRPL Lending Protocol and Single Asset Vaults.
The lending system targets institutional participants who want on-chain settlement without the capital inefficiency of overcollateralized models. Loan brokers would create lending terms, manage vaults and handle borrower relationships under defined ledger rules. If the XLS-65 and XLS-66 amendments pass validator voting, native vaults and fixed-rate lending would become part of the XRP Ledger's base layer.
For XRPL's DeFi infrastructure, the addition of native lending would expand the network beyond its established role in payments and cross-border transfers. Developers building on XRPL could integrate lending directly into wallets and liquidity tools without relying on third-party bridges or wrapped assets. The network already has tokenization and decentralized exchange infrastructure in place; lending would add a third pillar.
The clean audit result removes one of the most legitimate objections a skeptical validator might raise. The deeper question now is whether enough of the validator community sees the protocol as ready — and valuable enough — to bring on-chain.
